Description Hundred genotypes of green gram were evaluated to assess genetic divergence
using agro morphological traits and to study character association among seed yield and
yield contributing traits and also to assess the G E interaction for different traits in
summer, early kharif and rabi of 2015. Genotypes were screened to identify resistance
sources for powdery mildew in rabi. Based on ‘K means’ clustering approach, 100
accessions were grouped into six clusters. Cluster VI was the largest with 28 genotypes
and cluster IV had the smallest with eight genotypes and inter cluster distance indicated
considerable diversity among accessions. Morphological characterization clearly
indicated that, majority of the genotypes were towards dark purple stem and
hypocotyledon; green with purple spot petiole and erect growth habit; deltate leaf shape;
pendent, sparsely pubescent and light green pods; drum shape and light green seeds. At
both genotypic and phenotypic level, highly significant and positive association was
found between seed yield and yield components viz., clusters per plant, pods per cluster,
plant height, primary branches and seed mass. Path coefficient analysis revealed that
clusters per plant, pods per cluster and seed mass showed positive direct effect on seed
yield. Out of 100 genotypes, 22 genotypes showed stable performance for seed yield
across the seasons and 16 high yielding genotypes showed resistance to powdery mildew
disease. Genotypes viz., TM-965, LGG-587, LGG-573 and GMBL-1 were found to be
stable high yielding with resistance to powdery mildew disease.
