Studies on Genetic Variability, Correlation and Path Analysis for Yield and Yield Related Traits in Greengram [Vigna radiata (L.) Wilczek]

Studies on genetic variability and character association for yield and its attributes in greengram [Vigna radiata (L.) Wilczek]

“…In the present investigation, seed yield per plant recorded high significant and positive association with the number of pods per plant (r p = 0.810** and r g = 0.834**), followed by the number of clusters per plant (r p = 0.440** and r g = 0.534**), the number of seeds per pod (r p = 0.390** and r g = 0.530**), the number of primary branches per plant (r p = 0.396** and r g = 0.472**), plant height (r p = 0.392** and r g = 0.465**), days to maturity (r p = 0.320** and r g = 0.355**), pod length (r p = 0.212** and r g = 0.252**) and 100 seed weight (r p = 0.172** and r g = 0.224**). These results are in accordance with Ramakrishnan et al (2018) for the number of pods per plant; Sandhiya and Saravanan (2018) for the number of clusters per plant; Das and Barua (2015) for the number of seeds per pod; Ghimire et al (2017) for the number of primary branches showed a true relationship with seed yield per plant by plant establishing significant and positive direct effects both at the genotypic and phenotypic levels. Similar findings were obtained by Ramakrishnan et al (2018) for the number of pods per plant and plant height; Thippani et al (2013) for pod length and 100 seed weight; Kate et al (2017) for the number of primary branches per plant; Garg et al (2017) for harvest index and days to 50% flowering.…”

The residual effect was 0.460, indicating that along with the present characters there are some more characters like pods per cluster, biological yield per plant, pod yield per plant should be taken into consideration while formulating selection strategies for the yield improvement.…”

Genetic Parameters of Variation and Character Association for Seed Yield and its Attributes in Mungbean (Vigna radiata L. Wilczek)

“…The estimates of heritability and genetic advance as per cent of mean were high for the characters viz., plant height, clusters per plant, pods per cluster, pods per plant, seeds per pod, test weight and grain yield per plant indicating the probable operation of additive gene action in inheritance of these traits. Similar results for the above seven traits were earlier reported by Ahmad et al (2015), Muralidhara et al (2015), Anand et al (2016), Garg et al (2017), Shiv et al (2017), Mehandi et al (2018), Ramakrishnan et al (2018) and Sharma et al (2018).High heritability coupled with…”

Assessment of variability and association for seed yield and yield attributing traits among the interspecific derivatives of greengram x blackgram cross

“…Among the superior yielding progenies 3-2, 3-3, 3-12, 3-13 and 3-30, high heritability along with high genetic advance as per cent of mean was recorded by all the progenies for the traits plant height, number of clusters / plant, number of pods / plant and seed yield / plant. Similar results of high heritability and high genetic advance as percent of mean was recorded in the various populations of greengram was given by (Katiyar et al, 2015;Jeberson et al, 2017 andRamakrishnan et al, 2018) The progenies 3-2, 3-12 and 3-30 had high heritability and genetic advance as per cent of mean for the trait number of branches / plant. Among the superior yielding progenies 3-3 and 3-12 recorded high heritability along with genetic advance as per cent of mean for the trait number of pods / cluster.…”

“…The results emphasis that the progenies of the interspecific cross had high PCV and GCV values for all the traits studied. Similar reports of high PCV and GCV among the various populations of greengram for all the traits were given by (Suresh et al, 2010;Begum et al, 2013;Khaimichho et al, 2014 andRamakrishnan et al, 2018). High levels of variability were prevalent among the progenies which might be due to interspecific hybridization.…”
