Effect of low light intensity on key traits and genotypes of hilly rice (Oryza sativa) germplasm
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Low light intensity stress is a critical abiotic stress that reduces rice yield and quality. Present study has been carried out with a set of hill rice germplasm under ambient light and low light condition. Results related to principal components analysis (PCA) revealed that grain yield, plant height and pollen viability are the most informative components accounted for 63.95 % variance among the genotypes studied under low light condition. The three main traits contributing to PCA was. IRCTN 91-84, IRCTN 91-94 and RCPL 1-9C were found to be the most tolerant genotype to low light intensity under this study.
