Clustering of Greengram (Vigna radiata (L.)Wilczek) Genotypes Based on Qualitative Characters

Clustering of Greengram (Vigna radiata (L.)Wilczek) Genotypes Based on Qualitative Characters>

Greengram is an important grain legume of the arid and semiarid regions. This crop has enough genetic diversity both for quantitative and qualitative characters. The qualitative traits using minimal descriptors was developed by NBPGR. Enough work had been done in characterising the greengram using quantitative characters. In this study, fifteen qualitative characters were chosen for phenotyping the 40 greengram germplasm. The fifteen characters Early plant vigour, Plant growth habit, Leaf colour, Terminal leaf length (cm), Leaflet shape, Plant surface, Branching pattern, Flower colour, Leafiness, Flowering tendency, Raceme position, Pod pubescence, Pod colour, Seed colour, Hypocotyl colour. The crop was raised in Randomised Block Design with three replications at AC & RI, Madurai during kharif 2012. The data was subjected to statistical analysis and the results revealed that 40 greengram genotypes were grouped into six clusters at 40 % level. The variety ADT 1 is the distinct one differing from the other genotypes studied. It could be inferred from the present study that the geographical origin of most of the greengram germplasm is from the southern states of India having enough genetic variability in germplasm..
