Abstract

Rice (Oryza sativa L.), often known as “Global Grain”, is the primary diet of half of the world's population. The experimental area i.e., Gajapati district of Odisha lies between 18°.6’ to 19°.39’ North Latitude and 83°.48’ to 84°.08’ East Longitude. Climatic condition of this district varies between 16oC to 40oC and the normal rainfall received is 1403.30 mm. Analysis of variance for seven quantitative traits revealed highly significant mean squares due to genotypes for all the characters studied indicating that genotypes differed among themselves and there existed considerable variability. The mean performance of grain yield per plant ranged from 27.50g to 8.88g for the genotype Samba Mahsuri Sub1 and Swarna Sub1, respectively. The genotype namely, Samba Mahsuri Sub1 (27.50g) and JGL 24423 (19.47g) were found to be significantly higher grain yielder than the check, MTU 1061. The genotype namely, Hasantha and Sugandha Samba were found to be at par with check while, remaining genotypes showed significantly lower grain yield than the check, MTU 1061.
