Stability analysis in black gram (Vigna mungo L.) genotypes
Abstract
The present study was carried out to investigate the extent of genetic diversity and identify promising genotypes for future utilization. The experiment comprising of thirty five genotypes of urd bean was laid out with three replications in four environments in a randomized complete block design at Ganjbasoda, district Vidisha (Madhya Pradesh). The observations were recorded for days to 50% flowering, number of branches per plant, number of pods per plant, yellow vein mosaic incidence, days to maturity, plant height, biological yield per plant, 100 seed weight, harvest Index and seed yield per plant.
Stability analysis revealed that JU 8-6 appeared as promising genotype stable for seed yield per plant. It could be recommended for general cultivation to stabilize the urd bean production in Madhya Pradesh. BARC Urd -1 a high yielding genotype can be recommended for stress conditions. Other high yielding genotypes i.e. T-9, TU 92-3 and IU 83-4 were found suitable for favourable condition of crop growth.
