Heterosis for Yield, Yield Attributes and Water use Efficiency related Traits in Mungbean

Abstract

Among the constraints for low yield of mungbean, drought stress and heat stress are prominent. Water deficits and high temperature occur together in many environments and both stresses can interact to reduce yields. Improving the tolerance of crops to drought requires a broader

Genetic Analysis in Grain Legumes [Vigna radiata (L.) Wilczek] for Yield Improvement and Identifying Heterotic Hybrids

“…Thus, the significant assessments of both GCA and SCA variances indicated that both the additives and nonadditive nature of gene actions were engaged in controlling these characters in studied mungbean genotypes. These outcomes affirmed those discoveries by Reddy et al [33] Nath et al [44], Viraj et al [34], and Sopan et al [13]. The assessments of differences may be because of higher general combining ability than the specific combining ability for all the characteristics except plant height and seeds per pod brought up to be the dominance of non-additive gene effects in the outflow of these characters.…”

“…All traits showed variations between parents and cross-combinations because of heterosis, which were corroborative to the findings of mungbean [29,33]. Considerable positive heterosis compared with better-parent estimates would be enthusiasm for pods per plant, pod length, seeds per pod, and yield per plant, whereas it is helpful to have significant negative heterosis compared with better-parent esteems for days to flowering, days to maturity, and plant height.…”

“…Combining ability is an influential tool for identifying the best combiner, application of suitable crosses to assemble required genes, or accomplishing heterotic segregates [30][31][32]. The research of combining ability in diallel patterns is beneficial since it elucidates the nature and magnitude of different types of gene activities [33]. The majority of diallel investigations on gene activity and combining ability in mungbeans have shown a high prevalence of variability due to their general combining ability (GCA) [34].…”

Evaluation of Different Varieties of Sponge Gourd under Prayagraj Agro Climatic Conditions

“…Varieties that are genetically predisposed to respond more favourably to the prevailing environmental conditions, or those that have been selectively bred for early flowering, may show superior performance in terms of early initiation of flowering and thus maturing too. The findings were reported similarly earlier by Quamruzzaman et al, [4] in bottle gourd and Phan et al, [9]; Reddy et al, [10] in sponge gourd; Ramya et al, [6] in Bitter gourd.…”

Performance of Different Varieties of Sponge Gourd (Luffa cylindrica L.) in Terms of Growth, Yield and Quality under Prayagraj Agro Climatic Condition

“…AVT-2/2020/SPGVAR-5 showed the highest average fruit weight of 51.45 g among the various types, whereas AVT-2/2020/SPGVAR-3 showed the lowest average fruit weight of 38.38 g. Genetic and environmental factors can be related to a variety's superior performance over another in terms of enhanced fruit length, diameter, and weight [5][6][7][8][9]. Larger and longer fruits can be produced by cultivating fruit varieties with genetic features that encourage greater cell division and elongation.…”
