Yield components - Opis:
- An exploratory research was conducted to know genetic parameters and agronomical performance of three bacterial blight resistance genes introgressed segregating population of CB 174 R × IRBB 60, CB 87 R × IRBB 60 and TNAU CMS 2B × IRBB 60 in rice. Higher range of genotypic and phenotypic coefficient of variation (GCV and PCV) was found in CB 87 R × IRBB 60 for the trait of number of grains and leads to develop/selection superior genotypes significantly. For single plant yield, CB 174 R × IRBB 60 cross showed high heritability (83.89%) and (27.45%) genetic advance (%) suggesting that traits were primarily controlled by additive gene action and thus, leads to easy selection. Whereas, estimate of moderate heritability (56.09%) with high genetic advance (24.66%) was found in the cross of CB 87 R × IRBB 60 indicating that postponement of selection and for the cross of TNAU CMS 2B × IRBB 60 showed higher heritability with moderate level of genetic advance (67.36% and 11.84%), revealed that single plant yield was preponderantly governed by both additive and non-additive gene effects and selection may be rewarded.
