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
Abstract:A study was undertaken to evaluate the genetic parameters and correlation between the root and shoot traits in 50 upland rice genotypes of Manipur along with 3 checks for drought tolerance. The highest GCV and PCV values were recorded in Root fresh weight with 42% and 41.9% in controlled and 34% and 33.7% in stressed conditions. This was followed by Root dry weight (35.29% & 34.79% and 25.2% & 23.97%) in controlled and stressed conditions, respectively. The estimates of heritability were observed to be high in… Show more
