Assessment of genetic parameters and correlation studies in root and shoot traits among upland rice (Oryza sativa L.) of Manipur in relation to drought tolerance

A study was undertaken to evaluate the genetic parameters and correlation between root shoot traits in 50 upland rice genotypes of Manipur along with 3 checks for drought tolerance. The highest GCV PCV values were recorded Root fresh weight 42% 41.9% controlled 34% 33.7% stressed conditions. This followed by dry (35.29% & 34.79% 25.2% 23.97%) conditions, respectively. estimates heritability observed be high magnitude all characters. Heritability ranged from 80.32 per cent (number tillers) 99.7 (root weight) 92.36 99.36 (shoot length) Correlation reveals highly positive significant association at 0.01% both large variation found this population can exploited further develop a few forward breeding high-yielding lines better tolerance ability used as donors programs.
