Description |
A field experiment was conducted during kharif 2005 at Department of Horticulture, Main Agricultural Research Station, University of Agricultural Sciences Dharwad, to study the genetic variability, correlation and path analysis of capsicum. The experiment consisting 19 genotypes of capsicum was laid out in randomized block design with 3 replication. The analysis of variance revealed the experience of wide range of variation among the genotypes. The average fruit weight, pericarp weight, seed weight, number of fruits per plant, yield per plant, number of secondary branches and plant spread were having higher magnitude of genotypic and phenotypic coefficients of variation indicating these genotypes varied more widely for these characters, revealing great scope for selection. The characters like number of secondary branches per plant, pericarp weight, average weight of the fruit and number of fruits per plant had higher heritability (bs) coupled with high genetic advance which shows that characters could be compared through simile section procedures. Fruit yield per plant was highly and positively correlated with average fruit weight and pericarp weight and plant spread at the genotypic level. The genotypic path analysis revealed that the seed weight per fruit had the maximum positive direct effect followed by number of fruits per plant, plant height, number of secondary branches and average fruit weight suggesting direct selection through these traits will be effective in improving the yield of capsicum. Among the 19 genotypes, evaluated genotypes were high yielding compared to check (California Wonder) viz., 3bspc, 1cpsc, 4spc, BGM-1 and 3cspc showed significantly higher fruit yield over the check. These superior genotypes were high yielding but on par with the check for the characters like pericarp weight and average fruit weight. |
