Does biomass have impact on selecting Vigna mungo for organic farming under rain-fed conditions?

摘要

Under emerging challenges of climate change and enhanced demands for organic vegetable protein, black gram is a potential commodity that can successfully be grown with zero inputs due to favorable genes eco-friendly agricultural system. Seventy seven genotypes evaluated for three consecutive years indicated variability attributed genetic differences. The clustering patterns were affected by environmental effects that were further determined by principal components. Although performance for the germplasm was affected by the year effects, especially for maturity duration, however on the basis of average performance, 11 genotypes were identified and among these 45304, 45920 and 45921) were earlier than the check and produced considerably high grain yield. Selected genotypes are suggested for future testing under wide range of agro-ecological regions. It was obvious that the selected genotypes exhibited higher biomass that was partitioned to the economic yield, it should the selection criterion for suitable cultivars under rain-fed condition. Breeding program can utilize selected genotypes to improve black gram for organic farming.
