Evaluation of combining ability
WebThe line P1 was used as the drought-tolerant donor and CML247 was used as the recurrent parent. CML247 is an elite tropical inbred line developed by CIMMYT, with outstanding combining ability and good yield per se under well-watered conditions. It is susceptible to drought, in part because its ASI is large under drought.
