Abstract

On the basis of evaluation of 100 accession of pigeonpea (Arhar) from North-eastem region, it could be concluded that these were all tall, late maturing, indeterminate type and almost free from Heliothis infestation, whereas variable in other characters including seed coat colour. Plant height and seeds/pod contributed positively and directly, whereas contribution of 100 seed weight was negative to seed yield. While measuring their diversity, genotypes were grouped under three clusters. Cluster I was the biggest and cluster ncontained two germplasm which gave around 3500 kg/ha seed yield in around 270 days. Very high inter-and intra cluster distances suggested huge rage of variability among those germplasm belonging to North-eastem states.
