Summary of hybrid fruitbody development phenotypes analyzed by QTL mapping.

The N. crassa QTL mapping strains were crossed reciprocally to N. intermedia tester strains from India and Africa. Hybrid fruitbody development was measured in each of these four types of crosses. 1The N. crassa mapping strains are derived from an inter-clade NcA-Louisiana × NcC-India f1 cross. 2Crosses to Indian tester strains, which are sympatric to the NcC-India parent of the mapping population, are designated sympatric. African tester strains are allopatric to both parents.
