Abstract
The present investigation entitled "Studies on genetic architecture for yield and its components in brinjal [(Solanum melongena (L.)] was undertaken to elicit information on heterosis, heritability,enetic advance, nature and magnitude of gene action for three qualitative and twelve agronomic/morphological traits in six generations of ten crosses of brinjal. The 10 crosses were selected on the basis of yield performance from a diallel crosses made earlier during 1999. Thus, the material comprising six generations (P1, P2, F1, F2, B1 and B2) of 10 crosses were planted during February, 2002, in randomized block design with three replication at Horticulture Farm, Rajasthan College of Agriculture, Udaipur, Rajasthan. Parents and F1's were planted in single row, back cross generations in 3 rows while F2 were grown in 4 rows in each replications. Spacing of 75 x 60 cm was maintained between rows and plants. Recommended agronomical practices and plant protection measures were followed to raise the healthy crop. Significant variability among genotypes was found for all the characters. Oblong and oval fruit shapes over round; dark purple over light purple and reddish purple colour; and calyx spininess over non-spiny fruit were dominant. Parents Pusa Uttam and IC-90984 were identified as the most productive on the basis of their higher mean values for fruit yield and its component traits. Among hybrids, Pusa Uttam x Pusa Bhairav, IC-90984 x Pusa Uttam and IC-90984 x Pusa Upkar were superior for fruit yield/plant and its component traits.
