Sorghum is one of the prospective food crops to be developed in Indonesia. High yielding sorghum variety development is carried out through a series of breeding processes, including agronomic character selection among sorghum plants. The research's objective was to examine the stepwise regression model in selecting agronomic parameters that affect the yield of sorghum grain yield. Evaluation and modeling of the relationship between agronomic parameters and sorghum yield was carried out with two varieties of sorghum, namely Super 1 and Super 2, by using an experimental engineering approach. The estimation model based on information on the phenotypic character of sorghum was implemented using stepwise regression analysis. The results indicated that agronomic parameters affect the yield of sorghum was estimated in three stages, and the final yield equation is Y = -3.413 + 0.033 x2 + 0.561 x3 + 0.006 x5. The variables included in the model are x3 (panicle width), x5 (plant height at harvest), and x2 (panicle length). Correlation and determination coefficient values up to this stage were 0.82 and 0.68, respectively. This indicates that sorghum production can be optimized by the three significant variables: viz, panicle width, plant height at harvest, and panicle length. These results can then be used as a basis for selecting varieties to obtain high yield potential varieties.

The experiment was conducted at the Agronomy Field Bangladesh Agricultural University, Bangladesh to investigate the effect of planting dates on the performance of high yield potential varies of rice in Boro season. The experiment consisted of five dates of transplanting viz. 10 and 25 December 2015, 10 and 25 January and 10 February 2016: four high yield potential varieties viz. hybrid rice Sonar Bangla-1, Jagoran, BRRI Dhan-29 and BINA Dhan-6. Results indicated that there was a significant effect of date of transplanting on yield of potential varieties of rice in Boro season. It was observed that plant height, panicle length, grain yield, straw yield, number of tillers per hill-1 gradually increased up to 10 January. After 10 January transplanting yield reduced. The highest grain yield 6.41 t ha-1 was observed in hybrid rice Sonar Bangla-1. The result revealed that Sonar Bangla-1 emerged as the best variety in Boro season regarding grain and straw yields among the varieties studied and it should preferably be transplanted between 25 December to 10 January to obtain appreciable better yield.

Traditional rice cultivars in Sri Lanka have diverse characteristics that prove the excellent potential for utilizing them for varietal improvement. Seventy-one Sri Lankan traditional rice cultivars obtained from Plant Genetic Resources Center, Gannoruwa, Sri Lanka were used for diversity analysis. Data were collected in the middle-row-plants of each replicate and altogether 80 plants were evaluated in four replicates of each cultivar. Data were collected on 11 parameters in two consecutive Maha seasons in 2012-2014. According to the standard evaluation system of international rice research institute, 67% rice cultivars were tall, and 66% were low tillering. There was no any rice cultivar with high and good reproductive tillers/plant. Around 55% rice cultivars were partially sterile and 43% were fertile. The shortest days to maturity was recorded in Gonabaru (62 days) and the longest days to maturity was recorded in Vellainellu (105 days). The variation of agro-morphological characteristics was broad in studied rice cultivars: The recorded highest yield was 22.74 g/plant while the lowest was 1.55 g/plant. The hundred-grain-weight ranged from 3.49-1.27 g and the plant height ranged from 95-192 cm. The recorded highest number of total tillers per plant was 10 and the lowest was 3. Panicle length and panicle weight were ranged from 13-32 cm and 0.36-4.69 g consecutively. The smallest grains were in Herath and the largest grains were in Mudaliwi. The heaviest above ground biomass was achieved by Kallurundoivellai and its harvest index was the least (0.09). The highest filled grain percentage (91.48%) was recorded by Galpa Wee. The correlation analysis revealed that the yield per plant was significantly correlated with panicle weight, the total number of spikelets/panicle and number of fertile spikelets/panicle. There was no correlation between panicle length and the final yield of rice though panicle length was correlated with plant height and panicle weight. Total number of spikelets/panicle, the number of fertile spikelets/panicle, and plant height were significantly correlated with panicle weight. None of the parameters were correlated with hundred grain weight. Total biomass was correlated with plant height, the total number of spikelets, and fertile spikelets per panicle. There was no significant correlation between the biomass of rice with the final yield, however, a number of fertile tillers were correlated with a number of total tillers. Eleven parameters were sorted into four principal components that explained 87.44% of total variance and cluster analysis categorized the rice cultivars into six clusters at rescaled cluster distance 10 in Ward's linkage analysis.

Abstract This study aimed to obtain the homogeny of M8 soybean lines in an effort to release new high yielding varieties. The research was conducted in Lamsidaya village, and the observation of yield components was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Universitas Syiah Kuala. This study did not use an experimental design, so that the quantitative characters were observed individually from each plant, then analyzed by estimating the heritability broad sense value and the progress of selection. The material used were var. Kipas Putih and var. Dega1 as control, eight of 7th generation Kipas Putih mutant lines (B4, B7, B10, B12, B13, B15, B18 and B22). All genotypes were planted in rectangular plot 10 m x 1 m, drainage 50 cm, and planting distance 50 cm x 30 cm. Plants were maintained in accordance with the recommendation for soybean cultivation from Balitkabi, and fertilizer NPK (16:16:16) was given 200 g/plot (200 kgha-1). Parameters observed included plant height, flowering time, harvest time, number of productive branches, total number of pods per plant, number of filled pods per plant, percentage of filled pods per plant, seed weight per plant, weight of 100 seeds, seed weight per plot, and yield potential. All quantitative characters indicated increase on selection except for the character of plant height, percentage of filled pods and weight of 100 seeds because the heritability value was low. The B18 line has the potential to become a new high yielding variety because it has a high yield potential (3.02 tons ha-1) with a large seed size compared to the other seven mutant lines and is also higher than the parent Kipas Putih and var Dega 1 varieties.

An appropriate combination of plant density with nitrogen (N) fertilization can optimize corn growth and increase grain yields. This study evaluated the effects of nitrogen topdressing rates and plant density levels on the agronomic performance of corn. The early hybrid DKB 240 YG, with high yield potential and stability, was evaluated in two summer crops in Mauá da Serra, Paraná (950 m asl), in a Cfb climate, on a Rhodic Eutrudox. The experiment was arranged in randomized complete blocks and subdivided plots with four replications. The plant densities (60,000; 75,000; 90,000 and 105,000 plants ha-1) were assessed in the plots and the nitrogen (ammonium nitrate 32% N) topdressing rates (0, 60, 120, 180 and 240 kg ha-1) in the subplots. The stem diameter, plant height, ear insertion height and grain yield were evaluated. The stem diameter, plant height, ear insertion height and grain yield were influenced by the interaction between plant density and nitrogen topdressing under the tested high-altitude edaphoclimatic conditions. The stem diameter of corn plants decreased due to the increase in plant density whereas nitrogen topdressing attenuated this reduction. Maximum plant height was observed at a density of 75,000 plants ha-1 associated with a topdressing of 169 kg ha-1 of N, and highest ear insertion at 60,000 plants ha-1 and 168 kg ha-1 of N. Corn yield was highest at a density of 105,000 plants ha-1 associated with a topdressing of 185 kg N ha-1 of N.

This study presents the results of the variety comparison trials conducted with the French bean variety candidate BU-16 on sandy soil, during two years at the Research Center of the University of Debrecen.The outstanding characteristics of this variety candidate are the early maturity, the showy pods (yellow, straight, cylindrical cross-section „pencil bean”) and the high yield potential.The experiments were conducted with a randomized design, with five varieties and four replications. The varieties (of which two are foreign and three are domestic) were as follows: BU-16 fj, Maxidor, Paridor, Hungold and Budai piaci. The individual plots were 2 m wide and 4 m long. The seeds were sown at a density of 30 germs per m2, with a row spacing of 50 cm.The following parameters were taken: time of flowering, time of green maturity, plant height, height of the lowest pod above ground level, number of pods per plant, distribution of the pods by the state of development (20 plants), usable pod length (1 kg of standard crop-yield), yield per hectare based on the number of plants per plot. The experiments were evaluated statistically with Excel and SPSS softwares.Results obtained with the variety candidate BU-16:– The time from the emergence to green maturity is 45 to 46 days, which is short as compared with the other cultivars studied.– Plant height is 38cm (two years average), which is among the highest ones, together with Paridor.– The pods are set high above the ground level similarly to Paridor, the height of the lowest pod is 19 cm.– The average number of pods per plant is 13 (two years average) similarly to Paridor and to Maxidor.– The distribution of pod size in 2007 is as follows: 68% of the pods of BU-16 is of the standars size, which is a good rate. The value of this trait for the other varieties is 60 to 63%, except for Paridor, the value of which is similar to that of BU-16.– The usable pod length (10 to 14 cm) is 63% in 2007 and 84% in 2006. Similar pod length rates were obtained for Maxidor, while the rate for Paridor is as high as 91%.– The total yield and the standard yield of BU-16 is among the highest ones.According to the results obtained and presented above, the variety candidate BU-16 is the earliest maturing among the varieties tested with high yield potential which, however, is not significantly different from that of the others. Significant differences can only be detected in plant height and the number of pods per plant. Considering the results, BU-16 is to be further tested.

Rice (Oryza sativa L.) is the most important crops commodity in Indonesia because it is the main staple for the people of Indonesia but currently,  in Indonesia, the production of rice is still not maximal so it can not meet the demand of Indonesian people for national food needs. Therefore, it is necessary for rice plants that have high production and tolerant to various stresses. Plant breeding  is one of the ways that can be done to increase the production of rice, one of which is the method of cross-recurring selection. Genetic diversity is a variation of characteristics that are inherited in the same species population. This study aims to obtain information about genetic diversity and agro-morphological characters of 50 genotypes rice derived from the recurrent selection. This research was conducted from August until December 2017 in Rawa Makmur Village, Bengkulu Province with the height of place from sea level ± 2 m. The study used a Completely Randomized Block Design (RAK) with 3 replications. The seeds used were 50 genotypes of rice from previous cross-selection results from Bugis/N-22 crossbreeds, Bugis/IR-7858-1, Sriwijaya/N-148, Sriwijaya/IR-7858-1. The results showed that the genetic diversity of rice is quite narrow to moderate, but there are some rice characters that have medium to high heritability value that was plant height, harvesting age, flowering age, the total number of tillers and panicle length, so that character can be used for the next generation rice selection. The genotypes produced by Bugis/IR-7858-1 crosses have panicle length, filled grain per panicle, and high grain weight/hill resulting in high yield potential.

Sustainable production of food crops relies on germplasm improvement and genetic diversity that helps to identify appropriate parents, which is very important step in breeding of genotypes having high yield potential for future use. This study was conducted to investigate the extent of genetic diversity using multivariate technique on the basis of qualitative and quantitative traits. An experiment was comprised of 74 exotic genotypes and started at National Agriculture Research Center Islamabad, Pakistan during autumn 2017-2018 and 2018-2019. Data was recorded on qualitative and quantitative traits by following standard procedures and Biplot analysis was used to calculate the significance among the studied quantitative traits to exhibit the strength of relationship between traits. Results showed significant diversity in qualitative traits and quantitative traits. Red, yellowish, brown, light yellow, light brown color tubers were produced. Alike, genotypes produced yellow, cream and white flesh color tubers. Genotypes had oval, round, oblong, elliptic and reform with medium, small and large size tubers. Alike, brown, light brown, dark red and yellow eyes color was noted. In case of quantitative traits, genotypes had high variance regarding plant height, leaf area and number of tubers per lane. Genotypes had very high genetic variance for weight of tuber per plant and weight of tuber per lane while low variance was recorded for germination, number of stem per plant and number of eyes per tuber. Significant positive correlation was observed between number of tubers per plant (TPP) with number of eyes on tubers (r = 0.241) and number of tubers per lane (TPL) (r = 0.349). But negative correlation was noted between number of tubers per plant (TPP) with plant height (r = -246), leaf area (-0.529) and germination (r = -0.283). Plant height was found significantly positive correlated with leaf area (r= 0.456), germination percentage (r = 0.255) and weight of tubers per plant (r = 0.307). Leaf area (LA) showed positive significant correlation with number of tubers per plant (r = 0.466) and weight of tubers per plant (r = 0.263)., yield and harvest index (r = 0.798, 0.755, 0.255). Weight of tubers per lane (WTL) showed positive correlation with weight of tubers per plant (r = 0.387). Regarding the interrelation between the traits and genotypes, the first two principal component axes (PC1, 24.83% and PC2, 23.46%) accounted for about 48.29% of the total variability reflecting the complexity of the variation between the plotted traits of genotypes.

Heritability Analysis

In the plant breeding program, selection is one process which aimed to obtain some varieties with superior traits. Within this process, one of criteria that must be consider is the wide genetic diversity of the plant which was selected, and how these traits are inherited. The purpose of this research was to determine (1) the influence of cultivar differences and the colchicine concentration towards the growth and production of local corn cultivar from Kisar Island Maluku, (2) to determine the heritability of growth and production variables after induced with colchicine. Completely randomized block design  was used in this research with factorial design that consist of two factors i.e corn cultivar and colchicine concentration. The research procedure starts from field and seed preparation, immersion of seed into the colchicine solution, transplantation of seed into the field, plant maintenance, and  harvesting. The variable measured including growth and production variables of corn. The analysis of variance showed a significant effect of cultivar differences on all growth and production variables (p value > 0.05), while colchicine concentration only showed a significant effect toward the plant height and number of seed per ear.  The heritability analysis result showed that all variables observed were in high category. The different corn cultivars have a significant effect on all the growth and production, while the colchicine concentration only affect the plant height and number of seed per ear, and the heritability were in high category.  This research provides useful information to farmers how to use colchicine to trigger plant growth and production. It can be used as an information in selecting corn cultivars with high yield potential.

Abstract Sigupai is one of Aceh’s local rice that highly popular because of the distinctive scent. Sigupai is still widely grown by the farmers in the southern western region of Aceh. However, this local rice has inferior production, height plant architecture, deep age and the average of production about 4 tons ha-1. The improvement of Sigupai local rice from the agronomic character and the harvest age can be done through crosses with Yinzhan varieties that carry sd-1 genes. The study aims to analyze changes in agronomic character and fragrant gene inheritance in Sigupai/Yinzhan F2 derived. Analysis of agronomic character is carried out by observing harvest age, plant height, weight of 1000 grains, grain weight per clump and yield potential per hectare. The planting material used was F2 derivative of Sigupai/Yinzhan as many as 104 individuals planted in pots. PCR analysis was conducted to analyze the presence of fragrant genes in F2 progenies of Sg/Yz. The data was analyzed with Chi-Square analysis. The results showed 104 plant genotypes analyzed by PCR, 64.42% of F2 progenies Sigupai/Yinzhan inherited the fragrant gene. The results of analysis of agronomic character showed 62 genotypes there were 95.08% of ripening aged, 59.01% had a short stem architecture and 6 genotypes (9.83%) had a potential yield of 4,04,-5,33 tons ha-1.
