Genetic variability, heritability, genetic advance and path analysis in mungbean [Vigna radiata(L.) Wilczek]

Evaluation of Genetic Variability and Identification of Micronutrients Rich Recombinant Inbred Lines in Mungbean [Vigna radiata (L.) Wilczek]

“…This conveys that these characters are genetically controlled by additive gene action and can be improved through selection. Arshad et al, (2009), Gadakh et al, (2013 and Raturi et al, (2015) found similar results while Dhananjay et al,…”

Estimation of genetic parameters in white seed cowpea (Vigna unguiculata (L) Walp)

“…The coefficients of phenotypic variation in lines, check varieties and general, were less than 10.0% for all the characteristics studied, except for yield per plant that ranged from 17.56 to 20.47% (Table 1), which indicates reliability in these records, high accuracy and valid conclusions (Correa et al, 2012), being comparable to those of Silva et al (2014) and Agyeman et al (2015) and lower than those reported by Raturi et al (2015) in cultivars of Vigna unguiculata and Vigna radiata.…”

“…According to Johnson et al (1955), genetic advance the percentage of the mean was high (≥20%), moderate (10-20%) and low (0-10%); In this sense, pods per plant, peduncle length, 100 seed weight and days to harvest, accounted for the highest genetic gain GAM (%), with values of 36.06; 47.65; 84.11 and 87.07%, respectively (Table 2). Adewale et al (2010) and Raturi et al (2015) have reported significant advances with these characters.…”

“…(Table 2) and is consistent with that reported by Mohammed et al (2010), which is due to the genetic differences between the genotypes studied, since each contributes with a different genetic identity as Andrade et al (2010) and this allows a better selection margin for the evaluated characters (Ali et al, 2016), especially for pod length and pods per peduncle for fresh consumption, pods per plant, peduncle length, 100 seed weight, which presented values of 82.23; 90.32, 95.48, 97.05 and 98.51%, respectively, and also the selection of plants with a shorter peduncle length, for the sake of assimilates, to revert to the seeds, since the yield is associated with the length of pods, number of pods by plant and weight of 100 seeds (Mohammed et al, 2010, Manggoel et al, 2012, Silva et al, 2014. The efficacy of selection depends on the existence and magnitude of genetic variability for yield and yield traits in the breeding material (Adewale et al, 2010;Andrade et al, 2010;Raturi et al, 2015). Considering that the genetic control of quantitative traits as yield and its components is due to additive, dominant and epistatic genetic effects (Singh et al, 2016), heritability in conjunction with genetic advance alone is much better than the inheritance itself in the prediction of the best genotypes (Johnson et al, 1955, Ali et al, 2016.…”

“…The development of new cultivars according to the demand of producers and the satisfaction of a growing population was proposed by Singh (2007), who highlights the new generation of improved cowpea cultivars must combine high grain yield, erect growth habit, determinate growth pattern, an early to medium maturity cycle and branches with pods located above the plant canopy. Studies of genetic parameters for different plant characters have been reported in several agricultural species (Kumar et al, 2013, Raturi et al, 2015, Ali et al, 2016. In Vigna unguiculata, estimates of the most important parameters such as genetic variability, heritability and genetic progress, by direct and indirect selection, have contributed to significant genetic progress in characters of interest for its use in the conservation and development of cultivars with greater adaptation , Production and productivity, according to the needs, conditions and requirements of the producers, processors and final consumers (Andrade et al, 2010, Manggoel et al, 2012, Ribeiro et al 2014, Silva et al, 2014, Agyeman et al, 2015and Rambabu et al, 2016.…”
