| dc.description.abstract | The present investigations on the genotypic and phenotypic variability and correlation was carried out for nine characters in forty genotypes of Indian rape taken from different sources. Analysis of variance for nine characters revealed highly significant variations among the genotypes for all the characters. The range of variation observed in nine characters indicated a wide range of variation within characters. Highest range was observed in character, number of secondary branches per plant and lowest in days to maturity. The phenotypic coefficient of variation was highest for number of secondary branches per plant followed by number of siliquae per plant and number of primary branches per plant. Days to maturity had the lowest coefficient of variation followed by days to 50 % flowering. An may be seen from the table the phenotypic and genotypic variances of three characters viz; seed yield per plot, number of siliquae per plant and plant height were quite high. variation was found for number of secondary branches per piant. The character days to maturity had the phenotypic and genotypic coefficient of variation. lowest Highest heritability estimates was observed for days t 50% flowering (97.32) followed by plant height (84.13) number of secondary branches per plant (70.61) and days to maturity (70.20). The character number of seeds per silique had the lowest heritability. The expected genetic advance suggested relative differences among the different plant characters studied. The character, seed yield per plot showed highest genetic advance (52.36) followed by plant height (14.23) and number of siliquae per plant (12.15). The character 1000-seed weight showed lowest genetic advance. Genetic advance in percentage of mean was observed to be highest for character number of secondary branches per plant and lowest for the character days to maturity. Highest significant genotypic positive correlation of seed yield per plot was found with the character, number of seeds per siliqua followed by number of primary branches per plant. Positive significant phenotypic correlation of seed yield per plot was found with number of siliquae per plant. Findings of present investigation revealed that selection based on the characters, number of siliquse per plant, number of primary and secondary branches per plant will be more reliable. | |
