Gene action governing the inheritance of drought tolerance and selected agronomic traits in Ugandan groundnut (Arachis hypogaea L.) lines under drought environment

Breeding drought tolerance in groundnuts cultivars would reduce yield losses due to drought stress in rain-fed growing areas. The mode of gene action governing the inheritance of drought tolerance and secondary traits was investigated by mating 30 lines according to North Carolina design II scheme. The parents and resulting 75 F2 progenies were grown in a split plot arrangement using an alpha lattice design, with two replications under drought...
