Assessing Breeding Potential of Three-Way Cross and Double-Cross Hybrids in Chilli (Capsicum annuum)
Assessing breeding potential of multi-parent crosses is essential in order to isolate inbreds with broad genetic base. Five parental lines of chilli were used to produce ten single-cross hybrids in diallel design. These ten single crosses were in turn used to produce 15 double-cross hybrids and 30 three-way cross hybrids. The breeding potential of these three-way cross and double-cross hybrids was assessed for fruit yield per plant in terms of quantitative traits means, variances and their ability to produce transgressive segregants. Rank sums were also calculated based on individual means and variance. The hybrids which showed better values for all these parameters were compared and inferred that (Byadagikaddi × Gouribidanur) × (CCA 9907-9611 × Tiwari) and (CCA 9907-9611 × Tiwari) × PBC 483 have highest breeding potential and hence can be utilized for further improvement.
