Abstract: Predicting the performance of multi-parent hybrids even before their synthesis may conserve time and resources incurred during hybridization and evaluation. Five diverse chilli parental lines were crossed in half diallel mating design to produce 10 single crosses. Three- way cross and double cross hybrids were generated from single cross hybrids and evaluated for 4 quantitative characters viz., fruits plant-1, fruit length, average green fruit weight and green fruit yield plant-1. Their per se performance in terms of yield components were validated by two models, proposed by Jenkins, viz., mean of non-parental single crosses and mean of all possible single crosses among the parents involved in that cross. There was a perfect agreement between the observed and expected values in both prediction methods as per theory for all the traits under consideration, except for green fruit yield plant-1 suggesting that epistatic interaction might be involved in inheritance of this trait.
