Genetic Variability and Heritability for Yield and Yield Attributes in Field Bean (Lablab purpureus L.) Genotypes

Study of genetic variability and heritability in Indian bean (Lablab purpureus L.)

“…Results of analysis of variance for green pod yield and its component traits indicated (Table 1) that mean squares due to genotypes were found to be significant for all the traits and indicated the presence of sufficient amount of variability among the genotype for green pod yield and its component characters in Indian bean. This result was in accordance with reports of several workers like Pan et al 2001;Hotti, 2010;Dewangan et al, 2017, Hadvani, 2018Sadak Peer, 2018. The value of the phenotypic coefficient of variation was higher than corresponding genotypic coefficient of variation (Table 2) (Hotti, 2010;Hadvani, 2018;Sadak Peer, 2018) indicating the influence of environmental factors. The number of primary branches per plant exhibited the maximum values for genotypic and phenotypic coefficients of variation (Maharnavar, 2013) followed by the number of pods per plant (Chattopadhyay andDutta, 2010 andHadvani, 2018), pod length (Inamdar, 2014), 10-green pod weight, green pod yield and length of twig (Inamdar, 2014;Hadvani, 2018).…”

“…In the present study, high heritability (> 60%) was observed for all the 12 characters studied. The maximum heritability estimates were observed for the number of primary branches per plant (Magalingam et al, 2013) followed by twig length, pod length (Hadvani, 2018), 10 green pod weight (Inamdar, 2014), days to 50% flowering (Dewangan et al, 2017), green pod yield per plant (Inamdar, 2014 andVerma et al, 2014), pod width (Sadak Peer et al,2018), the number of pods per plant (Verma et al, 2014 andHadvani, 2018), days to first flowering (Venkatesha et al, 2016 andSadak Peer et al,2018), the number of pickings, days to first picking (Chaitanya et al, 2014) and days to last picking (Hadvani, 2018). Genetic advance expressed as per cent of mean was the highest for the number of primary branches per plant (Chaitanya et al, 2014) followed by the number of pods per plant (Chattopadhyay and Dutta, 2010), pod length (Sadak Peer et al ( 2018)), 10 green pod weight (Patel, 2014), twig length…”

Breeding for evolution of photo-insensitive pole type vegetable dolichos (Lablab purpureus L.) varieties to suit year round cultivation

“…Similar trend was reported in case of pod width wherein IIHR 15-23 followed by IIHR 15-5 recorded the highest pod width of 3.3 cm and 3.0 cm respectively and the lowest was recorded by check PEP with 1.3 cm. The results obtained are in synchrony with the experimental findings of Magalingam et al (2013), Parmar et al (2013) and Peer et al (2018) who reported a significant and wide range of variability with respect to various morphological traits that are indirectly governing the yield in dolichos bean.…”

Genetic variability analysis for yield and yield attributes among determinate “Wal” type Indian bean [Lablab purpureus (L.) sweet] genotypes

“…The RPP (0.51 % and 21.48 %, respectively) showed lower GCV and higher PCV values. Similar results are also there in earlier studies for DFF and DM byAsaduzzaman et al (2015); SYPP byPeer et al (2018); PLChoudhary et al (2016); PWD byNoorjahan et al (2019); PW and SPP by…”

“…This shows significant mean square values for all the characters in F 5 progenies indicating enough variability present among the progenies for all the traits. Similar results were observed byHadavani et al (2018),Peer et al (2018) andGamit et al (2020).…”
