Hybridazation in the breeding programme of an autogamous species is usually decided on the basis of complementary qualitative characters. Whenever quantitative traits are involved a relatively high degree of randomness is involved in the observed results. Recently, however, a new methodology has been developed for predicting the breeding potential of a cross allowing a reliable preview of the outcome of a breeding programme still in its early days. It has been applied to a soybean breeding programme in Parana State, Brazil. The correlations between predicted and observd proportions of inbred lines outyielding the check cultivars (Parana and BR-5) and their average, for 17 biparental crosses among well adapted materials, were 0.74, 0.61 and 0.77, respectively. Selecting the best six crosses based on their predicted potential to generate inbred lines outyielding the mean of Parana and BR-5 resulted in picking those crosses that were 1st, 2nd, 3rd, 5th, 6th and 7th placed in actual breeding potential. It was concluded that the new methodology allowed the early selection ofpotent crosses. |
