“…The variance analysis indicated, except for plant height, the existence of genetic variance in the traits primary branches, secondary branches, pod length, pod width, number of seed per pod, pods per plant, weight of 100 seed, and grain yield, in both environments; besides, it also showed genetic variance for days to flowering and days to maturity in environment II. Similar results have been reported by Pal et al (2018), Satapathy et al (2019), Gaur et al (2020), andPandey et al (2021). The precision of the experiments was evaluated by the coefficient of variation, which is considered low, medium and high, based on the evaluation criteria by Pimentel-Gomes ( 2009), who considers the values of coefficient of variation as low, when they are less than 10%, medium, when they are between 10 and 20%, and high, when they are between 20 and 30%.…”

“…The estimates of genetic parameters that make it possible to infer the feasibility of using selective practices, as well as their effectiveness, were determined for all traits (except for plant height and grain yield) exhibiting high heritability (above 75%), indicating an association between phenotypic and genotypic values in both environments (Table 2). Similar results were reported by Pandey et al (2021) and Sharma et al (2021), who observed high heritability for primary branches, secondary branches, days to flowering, days to maturity, pod length, pod width, number of seed per pod, pods per plant, and weight of 100 seed. Pal et al (2018) observed high heritability for days to flowering, days to maturity and weight of 100 seed.…”

The objective of this work was to evaluate the genetic variability and associations of yield traits of pigeon pea, for indication of this crop for the breeding program in Mozambique. Eleven pigeon pea traits were evaluated in a experimental design with three randomized complete blocks, in the environments of Namapa (I) and Montepuez (II), in 2017/2018. To evaluate the traits, analyses of variance, genetic parameters, correlations, correlation network, and path analysis were used. In both environments, there is a high genetic and phenotypic variability for primary branches, secondary branches, pods per plant, number of seed per pod, pod width, pod length, and yield, as well as a high heritability for all traits except for plant height. The primary and secondary branches have a high correlation with yield and a positive direct effect on it. However, plant height and pods per plant show a high phenotypic variability and a positive correlation with yield in environment I. Pods per plant, weight of 100 seed, and primary branches show high direct positive effects in environment I, and secondary branches and number of seed per pod, in environment II. The primary and secondary branches show high variability and associations with yield in both environments and are indicated for the pigeon pea breeding program in Mozambique.

Aims: To study morphological and genetic diversity among 100 Linseed (Linseed usitassimum L.) germplasm accessions. Study Design: Augmented RBD Design in five blocks with four checks. Place and Duration of Study: College of Agriculture, IGKV, Raipur, Chhattisgarh. During rabi 2020-2021 and rabi 2021-2022. Methodology: A total of 100 linseed germplasm accessions and four standard checks were studied by examining 10 quantitative traits which contribute to yield and its attributing traits. And observations recorded. Results: Outcome of the study revealed that analysis of variance for 10 quantitative characters showed differences for various characters. Results from genetic variability analysis state that the highest GCV/PCV was recorded for the traits 50% flowering, secondary branches plant-1, no. of capsules plant-1, and seed yield plant-1. Highest heritability was observed for all the traits under study. Highest heritability coupled with the highest genetic advance as percent was reported for 50% flowering, followed by secondary branches plant-1, no. of capsules plant-1, 1000 seed weight (g), and seed yield plant-1. Seven accessions such as LCK-9406, NL-126, Sumerpur Local, SJKO-8, L-103, EC-397752, R.S.-6 were recorded as having the highest oil content (%) greater than >42%. The highest seed yield plant-1 along with the highest oil content (%) was recorded in four accessions such as Sumerpur Local, EC-397752, LCK-9406, SJKO-8. Conclusion: The linseed accessions used in the current study showed significant variability for most of the characters. Observed accessions having the highest seed yield (g) and oil content (%) can be further utilized in the breeding programs based on breeder requirement.

Background: Pigeon pea is an economical source of protein cultivated in arid and semi arid tropical areas of the world. Genetic improvement mainly depends upon the amount of genetic variability available in the population. It is necessary for a breeder to understand the extent of genotypic and phenotypic variation among the germplasm to design an effective breeding programme. Methods: Eighty pigeon pea genotypes were evaluated for their variability with regard to yield and yield contributing traits. The experiment was carried out at Regional Research Station, Paiyur during 2021-2022 following randomized block design with two replications. Result: The traits viz., plant height, number of primary branches per plant, number of pods per plant and single plant yield can be improved following simple selection method as they exhibited high variability in combination with high heritability and genetic advance. Principal Component Analysis (PCA) revealed three significant principal components (PCs), which accounted for 81.24% of phenotypic variation among the studied genotypes. The traits days to 50% flowering, days to maturity, number of primary branches per plant, number of pods per plant and hundred seed weight had significantly positive association and positive direct effect with yield. Hence, these traits can be used as good selection criteria for yield improvement.
