Crossability and evaluation of incompatibility barriers in crosses between Capsicum species
The objectives of this study were to estimate the crossability rate in combinations of and assess the occurrence of incompatibility barriers between Capsicum species. The species C. annuum, C. chinense, C. frutescens, C. baccatum var. pendulum, and C. baccatum var. baccatum were crossed and the numb...
