Heterosis (vigor híbrido) y consanguinidad

Megal The estimated inbreeding depression from F 1 to next F 2 generation ranged from Based on these results, it was possible to highlight two hybrids of F 2 populations with high yield potential, high average heterosis and F 2 populations with potential for extraction of inbred lines. Introduction to quantitative genetics. Heterosis and inbreeding depression are complementary phenomena, both important to the establishment of breeding strategies, such as conventional heteosis and population breeding.
