Abstract:

Ten single cross hybrids of diverse origin of tomato were crossed in a 10 x 10 diallel mating design excluding reciprocals. The 45 double crosss hybrids along with their parents were evaluated in the field at COH, Mudigere following RCBD design with two replications. In the present study, significant and highest general combining ability effect for average fruit weight and number of fruits per plant was recorded in SCH-9(1.611 and 3.404 respectively), for yield per plant in SCH-9(0.152), number of locules per fruit lowest and desirable direction in SCH-10(-0.268), for pericarp thickness in SCH-5 (0.047) and for total soluble solids in SCH-1(0.694). Genetic components for GCA, SCA and GCA to SCA ratio were highest in number of fruits per plant and average fruit weight. Analysis of variance was highly significant for average fruit weight (gm), number of fruits per plant, fruit yield per plant (kg), number of locules per fruit, pericarp thickness (mm) and total soluble solids (TSS). Variance due to parents versus hybrids was highly significant for average fruit weight (gm), number of fruits per plant, fruit yield per plant (kg) and number of locules per fruit.
