“…Analysis of variance revealed significant differences for all the 30 traits under study (Table 1), suggesting exiatance of considerable genetic variation for yield, physiological and quality traits in studies super-early pigeonpea lines. These findings were in conformity with Ranjani et al (2018) andpushavalli et al (2018). Variability split into phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) sum ups the magnitude of variability.…”

Higher GAM was reported byRanjani et al (2018) (plant height; number of pods per plant; seed yield per plant; number of branches per plant), pushpavalli et al (2017) (days to 50% flowering; plant height) and Verma et al (2018) (number of primary branches). Moderate GAM was testified by Pandey et al (2015) (number of primary branches; seeds per pod), Kesh et al (2017) (number of pods per plant) and Vanishree et al (2013) (seed yield per plant) and low GAM was documented for 100 seed weight bySharma et al (2012) andMallesh et al (2017).…”

“…The association of pods per plant, secondary branches per plant, plant height and 100-seed weight with seed yield per plant was positive due to positive direct effects. Similar outcomes were also reported by Kothimbire et al (2016), Ram et al (2016), Kumar et al (2017), Ranjani et al (2018) and Singh et al (2019). Above results indicated that indirect selection for higher seed yield can be achieved through secondary branches per plant.…”

Background: Study of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) reveals the extent of phenotypic and genotypic variability in given population, respectively. Correlation and path analysis helps in identifying suitable selection criteria for improving the crop yield.Methods: Plant material comprised of 68 genotypes belongs to early maturity group of pigeonpea and experiment conducted during Kharif 2015-16 in randomized complete block design with two replications. Result: Traits, seed yield per plant (GCV=51.56%, h2=97.13%, GAM=104.67%) and number of pods per plant (GCV= 49.01%, h2=99.07%, GAM=100.49%) had high values of genotypic coefficient of variation (GCV), heritability (h2) and genetic advance as % of the mean (GAM) which indicated their additive genetic control. Plant height and number of seeds per pod recorded moderate to low heritability coupled with low GAM, indicating non-additive genetic control for these characters. Correlation analysis has revealed significant and positive association of seed yield per plant with number of pods per plant, plant height, secondary branches per plant, 100-seed weight and primary branches per plant. Path coefficient analysis identified number of pods per plant, secondary branches per plant and 100-seed weight as major traits affecting seed yield per plant directly and indirectly. The number of pods per plant and 100-seed weight should be given greater emphasis for improvement of seed yield in pigeonpea.

“…In F 3:4 generation, pods per plant (0.818) exhibited the highest direct effect on seed yield per plant followed by 100-seed weight (0.285) and seeds per pod (0.195), While fruiting branches per plant (0.783), plant height (0.204), seeds per pod (0.186), days to 50 per cent flowering (0.131) and days to maturity (0.120) exerted indirect positive effect on grain yield per plant via pods per plant. Similar findings were reported by Thanki and Sawargaonkar (2010), Devi et al (2012), Chaithanya et al (2014), Vijayalakshmi et al (2013), Chandana et al (2014), Kothimbire et al (2016), Ram et al (2016), Kumar (2017) and Ranjani et al (2018) in pigeonpea. Hence, in both generations direct selection for the pods per plant and fruiting branches per plant could be effective in developing high yielding genotypes in pigeonpea.…”

Segregating populations (BC 1 F 3 and F 3:4 ) from an interspecific cross (C. scarabaeoides × C. cajan) were evaluated for variability and association studies for yield and its component traits. In both the generations, high values of PCV and GCV were obtained for pods per plant, seed yield per plant and fruiting branches per plant. High estimates of heritability as well as genetic advance were observed for fruiting branches per plant followed by pods per plant and seed yield per plant. High heritability coupled with high genetic advance revealed the presence of less environmental influence and prevalence of additive gene action. Seed yield per plant had highly significant and positive association with pods per plant, fruiting branches and 100-seed weight. Path coefficient analysis revealed that pods per plant, fruiting branches and 100-seed weight contributing maximum towards seed yield per plant. The study revealed that fruiting branches and pods per plant could be used as selection criteria for improving yield.
