Identification of new microsatellite marker linked to the grain filling rate as indicator for heat tolerance genes in F2 wheat population

The objective of this study was to estimate inheritance of the grain filling rate as indicator for heat tolerant genes. The minimum number of genes for the trait in bread wheat was also assessed by combining quantitative genetic estimates and SSR marker analyses. Two cultivars, Debra (heat-tolerant) and Yecora Rojo (heat-sensitive) crossed and F1 and F2 populations generated. The parents, F1 and 162 F2 plants were planted in winter season 2009...
