Report on genotyping for identification of reproductive behaviour in Pm21 using marker assisted selection

Continuing with the implementation of the guinea-grass breeding scheme (M. maximus), a half-sibs population was formed through a factorial cross design. Using standardized protocols, the identification of the reproduction mode was carried out in the population of hybrids obtained (called Pm21) using...

description Continuing with the implementation of the guinea-grass breeding scheme (M. maximus), a half-sibs population was formed through a factorial cross design. Using standardized protocols, the identification of the reproduction mode was carried out in the population of hybrids obtained (called Pm21) using the molecular marker p779 / p780. A total of 3,156 (44%) hybrids, from 6,820, showed the apomictic marker, exhibiting apomixis: sexual ratio of 1: 1. However, among each of the 198 families formed, the apomixis and sexual ratio varied widely.
