Abstract

In an exploration undertaken In the hills zone of Assam, comprising Karbi Anglong and North Cachar Hills districts, a total of 76 hill rice genotypes were collected from 42 sampling sites. High variation was observed among the genotypes for all the traits studied. GCV and PCV were recorded high (> 50%) for yield per plant. Heritability estimates were recorded high for all the traits. A high estimates of genetic advance were recorded for grain yield per plant, grains per panicle, tillers per plant and spikelets per panicle. High heritability coupled with high genetic advance was observed in yield per plant, grains per panicle, tillers per plant and spikelets per panicle, which revealed predominance of additive gene action in inheritance of these traits. Three cultivars viz. Maibee Socket and Banglai were identified promising for grain yield per plant.
