Augmented Partial Diallel Cross Based on Circulant Sample

Abstract

At present, the parents are included in the experimental material for judging the performance of crosses over parents and for calculation of heterosis but they are ignored for combining ability analysis of Partial Diallel Crosses due to the non-availability of the method of analysis for such designs. To satisfy the practical need of the breeders on one hand and to remove the statistical objections on the other hand, a method of analysis of Partial Diallel Crosses based on circulant sample including parents has been presented in this paper. A numerical example is given for llustration of technique.

Blocking in Partial Diallel Crosses

“…, but are ignored for combining ability analysis, -a practice which is not free from objection. So to remove these objections on the one hand and to meet the requirement of breeders on the other hand Kaushik and Puri (1985), for the first time, gave the analysis ofPDC by including the parents in the sampled crosses. Singh and Hinkelmann (1995) have shown how the same Partially Balanced Incomplete Block Design (PBIB) can be used both for constructing the mating design (the PDC ) and the environmental design to evaluate the crosses of the PDC.…”
