| Summary, etc. | The present investigation on evaluation of yield and resistance to shoot and fruit borer of brinjal genotypes was conducted at the Department of Plant Breeding and Genetics, College of Agriculture, Vellayani, during the period 2000 - 2001. Data for the study was collected from two field experiments. For the evaluation of yield and its component characters of the 25 brinjal genotypes, a field experiment was conducted in randomised block design with three replications. Analysis of variance revealed significant difference among the genotypes for all the characters studied. Grouping of genotypes revealed that the genotypes VI (Swetha), V2 (Surya) and V18 (Pusa Purple Cluster) were better as far as yield per plant, number of fruits per plant and number of harvests were concerned. Pus a Kranti (V 17) had better fruit length, girth and weight. High phenotypic coefficient of variation and genotypic coefficient of variation were observed for yield per plant, number of fruits per plant, number of harvests, number of leaves per plant and number of secondary branches per plant. High heritability coupled with high genetic advance was also observed for these characters. At genotypic level, yield per plant showed high positive correlation with number of harvests, number of fruits per plant and fruit weight. The path analysis showed that number of harvests, fruit weight and number of 2 fruits per plant were the characters having high direct effect on yield per plant. The genotypes VI8 (Pusa Purple Cluster) followed by VI7 (Pusa Kranti), V21 (Brinjal Suphal), VI (Swetha) and V16 (Venganoor local) were having the highest index values. For screening of brinjal genotypes for resistance to shoot and fruit borer, a field experiment was laid out in randomised block design with two replications. All the 25 genotypes were significantly different for all the damage parameters. The genotypes V3 (CO-2), V17 (Pusa Kranti), V19 (Ark a Kusumkar) and V24 (Manjarigota local) came under the less susceptible category for all the damage parameters viz., percentage of plants infested, percentage of shoots infested and percentage of damaged fruits. The correlation studies on damage parameters revealed high positive correlation of number of bore holes per fruit with percentage of plants infested and percentage of shoots infested, while these damage parameters did not show correlation with percentage of damaged fruits. Percentage of damaged fruits showed high correlation with number of larvae per fruit. Cluster analysis based on different damage parameters and the yield obtained from the yield evaluation experiment enabled to group the genotypes into five clusters. The clusters Il and III were having the less susceptible genotypes viz., V3 (CO-2), V 17 (Pusa Kranti), V19 (Arka Kusumkar) and V24 (Manjarigota local) would be useful as parents for 3 developing shoot and fruit borer resistant varieties. Cluster IV had the high yielding genotypes viz., VI (Swetha) and V 18 (Pusa Purple Cluster). So hybridization programmes using genotypes from these three clusters could lead to the production of high yielding varieties with high level of shoot and fruit borer resistance. Based on the superior yield performance and low level of susceptibility to shoot and fruit borer, the genotype VI7 (Pusa Kranti) was found to be suitable for cultivation in borer endemic areas. Genotypes which showed high yield and those showed less susceptibility to shoot and fruit borer attack could be used in developing better yielding varieties with resistance to shoot and fruit borer. |
