GENOTYPE ENVIRONMENT INTERACTION IN RAGI (Eleusine coracana GAERTN)

Abstract

Fourteen genotypes of ragi wore investigated in terms of yield and its associated characters. The general association of yield with drymatter production was brought out Genotypes CO 7, IDS 1 and Indaf 5 doviated indicating their susceptibility to environment. The yield and 1000-seed weight relationship presented a wide scatter. The seed weight before sowing and seed weight after harvest differed widely in certaion genotypes. HPB 7 6 and PES 172 improved their 1000-seed weight largely whereas Indal 5 presented a decline. Only HR 222 showed resistance to environment interaction without any change in 1000-seed weight. Thus Genotype x Environment interaction is evident in the dry matter production and 1000 seed weight.
