Compatibility studies in Cola nitida genotypes

Cross and self-pollination compatibility studies were carried out using 10 Cola nitida genotypes from the Cocoa Research Institute of Nigeria, Ibadan. The few genotypes that were self-pollinated tended to show low pod production; whereas, crosses between the genotypes showed higher pod production. These data would suggest that multiple genotypes should be included in plantations to achieve higher levels of...
