ABSTRACT
Field experiment was conducted for evaluation and selection of rice genotypes under aerobic system of cultivation during Kharif 2015-16. In this experiment sufficient amount of variability was observed for grain yield per plant and its components among 125 genotypes evaluated under augmented randomized block design II in aerobic condition. The analysis of variance for grain yield and its attributing characters among blocks, treatments, checks and checks vs varieties revealed presence of significant variation in the genotypes studied. However, with respect to checks and checks vs varieties non-significant differences were recorded for panicle length and plant height. In these results indicated that, among the 125 rice genotypes only 50 rice genotypes expressed higher yield and its attributing characters with significant genotypic effect in comparison with five checks in aerobic system of cultivation. Among these 50, the genotypes viz., KMP-128, MTU-1075, NLR-3349, KNM-604, RNR-21245, CSR-27 and KMP-175 were the top ranking genotypes.
Key words: Aerobic rice, Sugmented block design II, Genotypic effect, Block effect
