Genetic divergence in redgram (Cajanus cajan L.) Mill sp.

摘要

Thirty seven redgram of medium duration (180 days) were raised in Randomized Block Design with two replications at National Pulses Research Centre, Vamban, Tamil Nadu during 1996-97. Each entry was sown in three rows of 4 m length adopting a spacing of 90 X 45 cm. Observations were recorded on 10 randomly selected plants for nine quantitative characters viz., 50 per cent flowering, plant height, primary branches, secondary branches, clusters/plant, pods/plant, pod length, seeds/pod and seed yield/plant. The data were analysed by Mahalonobi's D~2 statistics and genotypes were grouped into different clusters following the Tocher's method (Rao, 1952).
