Abstract:
The present investigation entitled “Assessment of genetic variability and qualitative traits of Rice (Oryza sativa L.) germplasm for yield and yield attributing characters" was undertaken to evaluate 72 germplasm accessions along with three local checks in rice for yield and yield attributing characters in rice with row to row and plant to plant spacing 20×15 cm. The experiment was carried out to study the morphological characters, to access the genetic variability and to estimate the correlation coefficient among yield and ant its contributing traits in rice germplasm. The experiment was carried out at experimental area of rice in instructional farm, College of Agriculture, Rewa (M.P.) during kharif-2018. The experiment was laid out in Randomized Block Design with three replications.
The analysis of variance revealed that highly significant variations were recorded among all the germplasm accessions for all the traits under study. It indicated that adequate amount of genetic variability were present in all studied characters. High estimates of phenotypic coefficient of variations (PCV%), genotypic coefficient of variations (GCV%) and high heritability coupled with high genetic advance as percentage of mean was recorded for were recorded for number of tillers per plant, number of productive tillers per plant, number of grains per panicle, biological yield per plant and grain yield per plant. These characters showed additive gene action in their expression.
The grain yield per plant had significant positive correlation with biological yield per plant followed by harvest index, panicle length, number of tillers per plant, number of productive tillers per plant, seed index and number of grains per panicle. The grain yield also showed negative correlation with plant height, days to 50 percent flowering and days to maturity.
