Analysis of morphological characters inter-relationships in the germplasm of mungbean [Vigna radiate (L.) Wilezek] in the hot arid climate
The 38 indigenous and exotic accessions of mungbean were evaluated in a randomized complete block design with three replicates during summer and kharif seasons of fragile climate of Rajasthan to estimate the presence of genetic variability, inter-characters associations, to identify a suitable short duration accession for cultivation during summer and to compare the relative performance of the genotypes in two seasons. The high degree of genetic variability was estimated during both seasons for seed yield per plant (g), 100-seed weight (g.), number of seeds per pod, number of pods per plant, number of pods per cluster, number of branches per plant, number of clusters per plant, plant height (cm.), number of days to 50% flowering and number of days to maturity. The moderate to high heritabilities coupled with moderate to high expected genetic advance were observed for all studied traits. Number of seeds per pod, number of pods per plant, number of pods per cluster, number of clusters per plant, days to 50% flowering and days to maturity had positive and significant correlations with seed yield per plant. The accession IC 39289-P4 had been identified to be of short duration of 50 days. The accessions PLG 62, EC 520035, IC 305291, IC 39383, IC 39333, IC 39403 during summer season and EC 511379, PLM-14, IC 324021, EC 511371, IC 370497 during kharif seasonexhibited superiority in terms of seed yield over best check.
