PHENOTYPIC STABILITY FOR GRAIN YIELD AND ITS COMPONENTS IN RAINFED AUTUMN RICE (ORYZA SATIVA)

Published on

Thirteen autumn rice genotypes were evaluated in three environments under rainfed and
direct seeded conditions. Both linear and nonlinear components of G x E interaction were
significant for productive tillers/m2 and grains per panicle, while only linear component
was significant for grain yield. Under medium yielding environment suitable genotypes
were China, Tulashi, Annada and Culture 1 for grain yield; lET 10898, lET 10895, Tulashi,
Annada and CR 635-49 for productive tillers/m2, and China and Annada for grains per
panicle. Rangadoria, a local genotype, was suitable for grain yield under low yielding
environment.
