Combining Ability of Potato Genotypes for Cool and Warm Seasons in Brazil
Crop Breeding and Applied Biotechnology
This study was carried out to identify potato cultivars with high combining abilities for heat tolerance and to get information about the individual performance of clones originated from crosses between heattolerant and heat-sensitive parents. Twenty six clonal families and more than 600 clones were assessed in warm and cool seasons in Brazil. High temperatures decreased tuber number and weight , resulting in 46% reduction in tuber yield. Furthermore, there was an eight-fold increase in tuberdoi:10.13082/1984-7033.v01n02a06 fatcat:ma6ylblsube4xb72ili7nbgesy
