Barley Genotypes

The present research revealed the study of genetic divergence and genotype (G) main effect and genotype by the environment (GE) interaction (G × GE) bi-plot analysis for multi-environmental trial data using yield data of three years. Since, genotypes were planted in 2017 in two dates like early and lates own condition hence, there was very slight differences in their yield so both the environments come together as compared to third environment (2018) which for from the two locations of year 2017. The objective of this study was to determine the effects of genotype, environment and their interaction on grain yield and to identify stable barley genotypes. The field experiment comprising of 69 barley genotypes laid out in a Randomized Block Design with three replications during Rabi 2016-2017. The extent of genetic variability, association between yield and yield components, frequency distribution of 25 top best genotypes in response to yield in three different environments, yield stability analysis and genetic diversity was studied. For stability analysis yield data of current year for one location and yield data of two locations/environments of previous year have been used. Field observations were recorded on six important characters days to 50% flowering, days to maturity, effective tillers per plant, plant height with awn, plant height without awn and 1000 grain weight (g). The result of bi-plot analysis using yield data of three years revealed that AXIS1 explained 57.6 per cent variation while AXIS2 was explained 31.07 per cent variation. Since, genotypes were planted in 2017 in two dates like early and late sown condition hence, there was very slight differences in their yield so both the environments come together (Figure1) as compared to third environment (2018) which for from the two locations of year 2017. Our result indicate that line G69 recommended as most stable genotype for yield potential and stability whereas lines G9, G55, G67 and G68 were consider as superior genotypes.

The experiment was conducted in the Dekarhaor of Noagaon village under South Sunamganj Upazila of Sunamganj district during November 2017 to February 2018 to observe the effect of nutrients management on growth and yield of cauliflower hybrids. Two Hybrids namely ShiraGiku (V1) and Rupali (V2), and four combinations of nutrients, viz. (i) recommended rate of N-P-K-S-Zn-B @ 180-80-180-28-4.5-2.1 kg ha-1(F1), (ii) F1 + 25% N-P-K- S-Zn-B of F1 (F2), (iii) F1 – 25% N-P-K-S-Zn-B of F1 (F3), and (iv)  cow dung @ 10 t ha-1 (F4)  was conducted in a factorial randomized complete block design (RCBD) and replicated thrice. Plant height (cm), numbers of leaves plant-1, leaf length (cm) and leaf breadth (cm), and spreading diameter (cm) were collected at 15 days intervals, while the yield data were recorded at harvest. The parameters were significantly varied due to hybrids and fertilizers packages. Higher gross yield (42.52tha-1) was found in Shira Giku and lower (42.12 t ha-1) from Rupali. Higher curd yield of 25.17 t ha-1 was obtained in Shira Giku than Rupali (9.61 t ha-1). The highest gross yield of 44.45 t ha-1 was obtained when the crop was treated with cowdung @ 10 t ha-1 followed by recommended fertilizer rate (F1). The curd yield of 18.19 t ha-1 was obtained with 25% less than recommended fertilizer rate of application (F3). The highest gross yield of 52.93 t ha-1 was obtained in V1F1 combination and the lowest of 30.10t ha-1in V2 F1. Results revealed that the Hybrid ShiraGiku with recommended dose of fertilizer (180-80-180-28-4.5-2.1 kg ha-1N-P-K-S-Zn-B) performed the best in comparison to other treatment combinations.

Hitherto, there is scarcity of information on the usefulness of neglected small corms and cormels of cocoyam in the South West Nigeria. A 9 (nine) months trial was conducted to compare the growth and yield performance of different types of cocoyam planting materials with treatment consisting of T1; sprouted small cocoyam cormels, T2, trimmed out lower parts of harvested cocoyam corm and T3; moderate sized corm of 50-100g (control) arranged in a Randomised Complete Block Design (RCBD) with three replicates. Data on the number of leaves and plant height was taking at 4 week interval for 24 weeks while data on number and weight of harvested cormels was taking at 9 months after planting (MAP). The data collected were subjected to a univariate General Linear Model (GLM) two ways Analysis of Variance (ANOVA) using IBM SPSS software statistical package 21. Significance mean differences were separated using Duncan Multiple Range Test (DMRT) at 0.05 level of significance. The result showed that the highest mean number of leaves and plant height was obtained from treatment T1 (10.22) and T2 (92.83) respectively at 24 weeks after planting (WAP). While both treatment T1 and T3 collectively had the highest number of consumable cormels (54.0) in which treatment T3 weighed the highest (3.202 kg). There was no significant difference (P>0.05) in both the number of leaves produced and plant height among the different cocoyam planting materials utilised at 24 (WAP). Similarly, there was no significant difference (P>0.05) in the number and weight of cormels produced by the different treatments at 9 months after planting (MAP). The study therefore concluded that both sprouted small cocoyam cormels, trimmed out corms during planting compared favourably with moderate sized corm of weight 50-100g commonly used as planting material in term of yield potential and therefore recommended to be schedule for demonstration to cocoyam farmers in the study area for adoption.

To study the effects of nitrogen (N) rate and co-inoculation of nitrogen-fixing bacteria (Rhizobium phaseoli) on common bean, an experiment was performed in Rasht, Iran. Common bean genotype, Guilanian landrace, was planted in a factorial experiment based on a randomized complete block design with three replicates on April, 15th in 2014. The first and second factors were nitrogen rates (0, 30, 60, 90 and 120 kg.ha-1 as urea) and Rhizobium phaseoli (inoculation and un-inoculation), respectively. Nitrogen had significant effect on seed yield and plant height. The effect of Rhizobium phaseoli was significant on seed yield, plant height, pod length, pods per plant, seeds per pod and nitrogen content in leaf. Interaction effects of nitrogen and Rhizobium phaseoli were not significant on any of the traits. Application of 60 kg.ha-1 nitrogen significantly improved seed yield, plant height and number of pods per plant. Nitrogen supply beyond the 60 kg.ha-1 decreased plant height, pods per plant and seed yield. The greatest values of seed yield (1635 kg.ha-1), plant height (30.01 cm), pod length (13.19 cm), number of pods per plant (6.7), number of seeds per pod (4.34) and nitrogen content in leaf (4.12%) was observed in inoculation treatment. The results indicated the inoculation of common bean seeds by Rhizobium phaseoli improved the plant growth, productivity and quality. Therefore, the common bean inoculation with Rhizobium phaseoli is suitable to achieve the yield potential and reduce the adverse effects of environmental and may be recommended due to its advantages in terms of reduced application of nitrogen fertilizer.

<p class="abstrakinggris">Soybean breeding program in Indonesia has been actively involved in improving the genetic yield potential to meet the needs of farmers in different parts of the country. The study aimed to determine the presence of soybean production mega-environments and to evaluate the yield performance and stability of 12 soybean genotypes. Soybean yield performances were evaluated in eight production centers in Indonesia during 2013 growing season. The experiment in each location was arranged in a randomized complete block design with four replications. Parameters observed included grain yield and yield components. The yield data were analyzed using GGE biplot and the yield components data were analyzed using analysis of variance. The results showed that the yield performances of soybean genotypes were highly influenced by genotype-environment interaction (GEI) effects. The yield components were significantly affected by GEI except per plant branch number. The partitioning of the G + GE sum of squares showed that PC1 and PC2 were significant components which accounted for 57.41% and 18.55% of G + GE sum of squares, respectively. Based on the GGE visual assessment, agro-ecology for soybean production in Indonesia was divided into at least three mega-environments. Genotypes 8 and 2 were the best yielding genotypes in the most discriminating environment, but adapted to specific environment, thus highly recommended for that specific location. Genotypes 9 and 10 were stable and had relatively high yield performances across environments. Those genotypes would be recommended to be proposed as new soybean varieties.</p>

A field experiment aimed at determination of influence of season on the yield potential of some cowpeas lines was carried out at the Teaching and Research Farm of Federal University of Agriculture, Abeokuta, Nigeria located on Latitude 7012' N and longitude 3020' E during the late rain season (August- November 2013) and early rain season (April- July, 2014). The experiment was laid out in a randomized complete block design with three replicates. Qualitative and quantitative data such as stem petiole pigmentation, leaf colour, flower form and colour, dry pod colour, seed coat texture, plant height, number of days to flower and first ripe pod, pod length , total number of pods/plant , total number of seeds/plant, 100-seeds weight were taken. Combined analysis of variance to determine line x season interaction, while SASTM 9.1, (2000) version statistical package was used to separate the means, Pearson correlation analysis was used to determine the inter-character relationships among the traits. Major characters causing variation within the population was calculated using Principal component analysis (PCA). Most of the cowpea lines were non-pigmented and papillinaeous, except Rosa-1 and 2 that showed rosaceous flower form. Cowpea lines such as Rosa-2, IF-Br-Y-2 and IB-Cyt.Y had yellow foliage, while the flower colour ranged from solid purple and white to white petal with purple wings. Line x season interaction revealed a high level of significance for most of the traits studied. Means of the cowpea lines’ traits were significantly different from one another. Pod length was highly correlated with number of seed per pod, pod per plant and 100 seed weight (r = 0.63, 0.45 and 0.66) respectively, while plant height had a negative and highly significant correlation with days to flowering (r = -0.58) and days to fruiting (r = -0.60).

The knowledge of nature and the magnitude of divergence existing in the breeding materials are useful to identify suitable parents or populations to combine favorable genes. Thus, 28 barley genotypes were evaluated at Gitilo site in RCB design with three replications during the 2018/19 season. The aim of the study was to investigate the magnitude of genetic divergence among the existing breeding materials. The result revealed that the barley genotypes were grouped into four clusters. The inter-cluster distance was greater between clusters I and II, followed by cluster II and III and then between clusters II and IV, I and IV, III and IV, between I and III so that crossing among parents from distant clusters result in wide array populations with desirable alleles. Besides this, cluster mean analysis showed clusters IV and III contained desirable characters for high yield potential including net blotch and scald resistance indicating their suitability for direct variety development. The variation studied through principal component analysis revealed four principal components (PC1:32.7%, PC2:22.4%, PC3:16.7% and PC4:11.6%) accounting for about 83.4% of the total variation. Furthermore, the biplot graph identified barley genotypes or populations 21, 20, 24 and 12 as desirable parents mainly for grain yield, biomass yield per plant and thousand kernel weights.
