GENETIC DIVERGENCE IN EARLY RICE UNDER TWO SITUATIONS

Published on

Genetic divergence was studied for yield and its eleven component traits in 28 early rice
varieties (Oryza sativa L.) under direct seeded and transplanted conditions. The strains
were grouped into five and six clusters in direct seeded and transplanted conditions,
respectively. There is no relationship between geographical distribution and genetic
divergence. Stable genotype like RP 1670-6-36-14 having wider genetic distance with cluster
II and RAU 4045-2A are desirable to use as donor parents in hybridization programme for
improvement of both direct seeded and transplanted conditions.
 

Keywords: Genetic divergence, early rice, direct seeding, transplanting.
