“…The low estimates of phenotypic and genotypic coefficient of variation were observed for the parameters 100 seed weight (g) (8.5 and 0.02), days to 50% flowering (8.0 and 7.4) and days to maturity (7.1 and 0.30), indicating the major role of genetic factors changing the expression of these traits. The above findings were accordance with the findings of Punia et al, (2013), Panigrahi et al, (2014), Deepshika et al, (2014), Babu et al, (2016), Singh et al, (2016), Priyanka et al, (2016) and Hemalatha et al, (2017), Chaithanya et. al., (2019.…”

Background: The present investigation was undertaken to examine the genetic variability and association between morphological traits among the 22 advanced lines including 3 checks of urdbean diverse collections. Genetic variability and association studies play an important role in developing a new genotype. The urdbean productivity remains low in India because of the low genetic base for yield improvement, limited amount of variability for yield traits, poor ideotype of urdbean plant, inadequate management of the crop, weed infestation and susceptibility to abiotic and biotic stresses. Genetic variability is the most important factor in the success of any crop improvement programme. Methods: An experiment was laid out in a completely randomized block design with three replications at Regional Agricultural Research Station, Sagar, Madhya Pradesh in high productive black cotton soils during Kharif 2014 on 22 advance lines including 3 checks. Each plot comprised 6 rows of 4 meter length with 30 cm distance between rows and 10 cm between plants. Result: The study found that the mean amounts of squares due to the genotype were very significant for all morphological characteristics except 100 seed weight. High estimates of heritability and genetic advance were recorded for seed yield, days to maturity and plant height indicating the role of additive gene effects with little environmental influence in determining these traits and simple phenotypic selection can be effective. The results also indicated improvement through direct selection for these traits can increase directly the grain yield in Urdbean.

“…The highest genetic gain was reported for seed yield per plant followed by plant height, 100-seed weight, harvest index and the number of pods per cluster representing that these traits are controlled by additive genetic variance to a large extent and improvement of these traits through selection would be rewarding.These findings are in agreement with the results of Aftab et al (2018) and Chaithanya et al (2019) for seed yield per plant. Moderate genetic gain was observed for the number of branches per plant, pod length, the number of cluster per plant, the number of pods per plant, the number of seeds per pod and biological yield per plant.…”

“…Estimates of high heritability were reported for 100seed weight followed by plant height, pod length, the number of clusters per plant, the number of branches per plant and the number of pods per cluster indicating a low environmental influence and high ability of these traits for transmission to next generations. Results are in harmony with some previous findings of Konda et al (2009), Kuralarasan et al (2017), Aftab et al (2018) and Chaithanya et al (2019) for the number of clusters per plant, plant height and the number of branches per plant. The traits viz., days to 75 per cent maturity, seed yield per plant, biological yield per plant and seed protein content expressed moderate heritability.…”

“…The highest GCV was found for seed yield per plant followed by harvest index, plant height and 100-seed weight which suggested the possibility of improvement through selection in these traits since they had abundant genetic variation among genotypes. Similar results were also obtained by Panigrahi et al (2014), Babu et al (2016), Aftab et al (2018), Panwar et al (2019) and Chaithanya et al (2019) for seed yield per plant, plant height and harvest index. The traits viz., the number of pods per cluster, the number of branches per plant, biological yield per plant and the number of clusters per plant were exhibited a moderate GCV.…”

“…This indicates that the expression of these traits considerably influenced by the environment. Aftab et al (2018) and Chaithanya et al (2019) were also found similar results for seed yield per plant and harvest index. Moderate PCV estimates were observed for plant height, the number of branches per plant, the number of pods per cluster, biological yield per plant and 100-seed weight.…”

An investigation was carried out during kharif, 2018 in Randomized Block Design to estimate the variability parameters in blackgram using thirty five genotypes including two checks viz., Pratap Urd-1 and Pant Urd-31. The results of ANOVA showed that the genotypes varied significantly for all the traits. The high GCV and PCV estimates were recorded for seed yield per plant, plant height, harvest index and 100-seed weight. High magnitude of heritability combined with the high genetic gain was found fortraits viz., plant height, the number of pods per cluster and 100-seed weight. Therefore, direct selection for the traits like, plant height, harvest index, 100-seed weight and the number of pods per cluster would be useful for increasing seed yield in blackgram.

Black Gram (Vigna mungo L. Hepper) is most prevalent types out of pluses crops 80 genotypes of Black gram collected from Bastar Region (Dantewad, Sukma, Bijapur, Kondagoan, Narayanpur, Kanker districts). The experiment was conducted in Randomized Complete Block Design (RCBD) with two replications comprising two check varieties viz. Indira Urd Pratham and T.U. 94-2.Crop growing spacing 30×10cm during Kharif 2019 in Research cum Instructional Farm of SGCARS Kumhrawand, Jagdalpur, Bastar (C.G.). Analysis of variances indicated presences of significant genetic variability for thirteen biometrical traits in Black Gram genotypes. Highest GCV and PCV estimated for seed yield per plant, plant height (cm), number of primary branches per plant and test weight of thousand seeds. High heritability and genetic advances indicated least influenced of environment on the expression of character and characters governed by additive genes respectively. High heritability accompanied with high Genetic Advance as percent of mean observed for the traits plant height (cm), Test weight of thousand seeds, seed yield per plant (g), harvest index (%) and petiole length (cm) due to additive gene effect abundant sources provided for improving the traits though section.
