Studies on Character Association and Genetic Divergence in White Jute (Corchorus capsularis L.)

Background: In white jute, very limited success has been reported by researchers to break yield plateau due to the narrow genetic base of the genetic material available with the breeders. Evaluation of agronomic traits and information about genetic variance in the breeding population is essential for selection and in planning crosses to enhance the productivity and diversity in cultivars. Yield character components are inherited and each one accounts for variations in yield, hence interrelated with each other. The current investigation was done to measure the genetic variability and genetic diversity of white jute genotypes for characters and interrelationship that contribute to yield and fibre quality.Methods: In the present study, fifty-two white jute (C. capsularis L.) genotypes were assessed during the Pre-Kharif season of 2017 at the Teaching Farm of Bidhan Chandra Krishi Viswavidyalaya, Mandouri, Nadia, West Bengal. Plants were raised in randomized block design with three replications. Statistical analysis was done for the estimation of ANOVA variability, correlation and path analysis and genetic divergence.Result: Plant height and bark thickness with high heritability and high genetic advance were identified as important selection parameters. Plant height, bark thickness and green weight per plant had a significantly high positive correlation with dry fibre weight per plant both at genotypic and phenotypic levels. Plant height had the highest contribution toward the dry fibre weight followed by bark thickness. Genotypes were grouped into 13 clusters and cluster I had the highest number of 23 genotypes. The inter-cluster distance was found maximum between cluster I and cluster VI. Cluster XI recorded the highest mean for the plant height. Ten genotypes identified from different clusters in this study can be incorporated as donors in hybridization to combine both yield and improved fibre quality.

Stress events or leaf damage can alter the redistribution of photoassimilates and modify the morphological traits directly related to grain yield. This study aimed to evaluate the influence of agronomic traits on grain yield in soybean crop in function of leaf defoliation. The experiment consisted of a randomized block design with three replications, arranged in a 6 x 3 + 1 factorial scheme. The factors were composed by six reprodutive stages (R1, R2, R3, R4, R5, and R6) and three defoliation levels (33%, 66%, and 99%), and one additional treatment without defoliation (control). The following traits were evaluated: plant height, number of pods per plant, number of grains per pod, thousand grain weight, and grain yield. The magnitudes of the correlations between the same traits showed high oscillation according to the defoliation level. Results revealed the potential for the indirect selection for grain yield by the traits plant height and number of grains per pods under 0% of defoliation and by the trait number of pods per plant under 33% of defoliation.

ABSTRACT The staple diet of most of the world population is provided by cereal, which present levels of iron (Fe) and zinc (Zn) below the nutritional demand of humans. Other factors that may substantially interfere for the low intake of Fe and Zn are the anti- nutritional factors present in the edible parts of plants, such as heavy metals and phytate. Hence, the objective of this study was to evaluate the genotypic variation in terms of yield (kg ha-1), plant height, insertion height of first pod, as well as concentrations of Fe, Zn, phosphorus (P) and the anti-nutrient phytate in grains of 24 soybean cultivars and to identify cultivars with potential for biofortification. The field experiment was conducted in Rio Verde, state of Goiás by the technological center of COMIGO. The experimental design used in the study was a randomized block design with 24 treatments and three replications. The results showed that there is genotypic variation for grain yield (kg ha-1), plant height, and insertion height of first pod, as well as for the concentrations of Zn, Fe, P and concentration of anti-nutient phytate in grains among the soybean cultivars. Non-significant or low correlations were found among the evaluated parameters except for the relationship between P and phytate (r=0.733). The diversity found among soybean cultivars offers genotypes such as 8197RR, M 7908RR and BRS 262 with potential to develop cultivars with better ability to accumulate nutrients in grains.

Rice is the staple food of Indonesian people and part of the world community. Indonesia, with a population growth rate of around 1.3-1.5% per year, requires additional rice production of about 1,8- 3 million tons of rice per year. This additional production can be achieved by using tidal swampland which is quite a large area in South Kalimantan. However, one of the obstacles in tidal swampland is the lack of nitrogen (N). N is a macronutrient that becomes the main limiting factor for plant growth as it is needed most among other nutrients. This study aimed to determine the agronomic traits of superior varieties at various N concentration. The experiment used a Split plot design with N concentration as the main plot and three rice varieties as sub-plots, while the environmental design used Randomized Block Design based on the direction of water flow. The agronomic characters observed were the number of leaves, number of tillers, plant height, the total number of panicles per plant, 1000 filled grains dry weight rice, and yield (t ha-1). The results showed that different varieties affected the plant height, number of leaves, number of tillers, the weight of 1000 grains of filled grain with IPB3S and IPB Batola 6R as the best variety, and the concentration treatment effect total of rice tillers, total of rice leaves and total number of per plant with 300 t N ha-1 as the best concentration.

The Impact

Exposure of bulbs to cold, a physiological phenomenon called vernalization, and bulb size are important factors in the production of lily bulbs and flowers. This study aimed to verify the influence of vernalization of bulbs on flowering cut lily plants, as well as the impact of size and shape of harvest on the production and quality of flowers and bulbs. In turn, the way the stems of the plants used for cut-flower production are cropped is of higher importance for the production of new flower bulbs. In this sense, the experiment was conducted in Viçosa, MG, in a greenhouse in a randomized block design, in split splot scheme with three replications, in which the vernalization periods (25, 35 and 45 days at 4 ± 1 C) constituted the plots; bulb sizes (diameters of 3.2-3.8 cm; 2.5-3.2 cm 1.9- and 2.5 cm), subplots and ways to harvest (full harvest of the stem at the required length for the commercial harvest of the flower, commercial stem harvest at the commercial length, maintaining 10cm of stem in the soil; removal of the floral buds as soon as their appearance is observed and harvest at the end of the season), the sub subplots. The bulbs were planted in beds, with 15 x 20 cm spacing. It was evaluated the number of plants that flowered and the number of flowers, the length and the diameter of the floral buds, fresh and dry weights, diameter and plant height as well as number, perimeter and amount of fresh and dry bulbs. There was a decrease in the plant height with the increase of the vernalization period and a reduction of the diameter of the planted bulbs, as well as of the number and the fresh and dry weights of the produced buds. The production of flowers and buds in number, size and weight was directly proportional to the size of the planted bulbs, while the form of harvest with removal of flower buds increased the number, the perimeter and the fresh and dry weights of the buds. Bulbs with diameter between 3.2 - 3.8 cm, stored for 25 days in cold chamber enable greater production of flowers and the highest stem height, factors that favor the increase in market value.

The characterization of maize landraces is extremely important in breeding programs for use of these genotypes as sources of genetic variability. The objective of this study was to quantitatively characterize 28 populations of maize landraces from the state of Paraná using the estimates of the effects of varieties and heterosis parents and the general combining ability, thereby assessing the main agronomic traits. In the crop of 2008/09, 56 inter-varietal hybrids, obtained through a topcross, 28 populations of maize landraces and three check varieties were evaluated for female flowering (FF), plant height (PH), ear height (EH) and grain mass (GY). The treatments were evaluated in a randomized block design, with two replications, at three Paraná State locations: the Experimental Center of the Agronomic Institute of Paraná in Londrina (IAPAR) and the experimental units of Pato Branco and Ponta Grossa. The data were submitted to an analysis of variance, considering a fixed model for genotypes and a random model for environments; the averages grouped by the Scott-Knott test, along with intersections of topcrosses, were analyzed according to a readapted model proposed by Oliveira et al. (1997). According to estimates of the parental effects, the GI 133 population showed the most promising estimates for all characteristics. The GI 088 and GI 173 populations stood out with promising estimates of the effects of heterosis. The conclusion is that the populations GI 133 and GI 173 may be indicated for recurrent selection programs or participation in obtaining composites.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

ABSTRACT The objective was to evaluate the effect of different spacings and mineral fertilizations on cactus pear growth and production in a randomized block design, with three replicates, in a 3 x 4 factorial scheme: three spacings, 1.00 x 0.50 m, 2.00 x 0.25 m and 3.00 x 1.00 x 0.25 m, and four fertilizations, 000-000-000, 000-150-000, 200-150-000 and 200-150-100 kg ha-1 of N, P2O5 and K2O, respectively. Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.
