Abstract:
The present investigation consisting of fourteen genotypes of rice was carried out with in order to obtain information on genetic variability, heritability and genetic advance for important yield attributing and nutritional traits. The analysis of variance revealed significant differences among all the genotypes for all the characters studied. High range of observed values was discerned for total number of tillers, days to 50 % flowering, number of productive tillers, plant height, days to maturity, panicle length, shoot dry weight and grain yield per plant. The phenotypic variance was in general greater than the genotypic variance for all the characters. High heritability was recorded for all the characters studied. Moderate PCV as well as GCV were observed in days to 50 % flowering and plant height. Low PCV and GCV was observed in days to maturity. Less difference between PCV and GCV with high heritability and high GAM was found for number of tillers, number of productive tillers, days for 50 % flowering, days to maturity, and grain yield per plant for yield associated characters suggesting that selection among the elite accessions for micronutrients should be done for only the above mentioned traits, thus reducing the effort, time and labour for future work.
