After eight cycles of selection for many-eared plants, the average yield and prolificity of Harinoso Mosquera I Sin. 2 [Floury Mosquera I Syn. 2] were 35% and 39% higher respectively than in the original population. Selection for single-eared plants did not affect yield but caused a decrease of 10% in number of ears per plant. Prolific plants were physiologically more efficient in accumulating photosynthetic products in the ears than nonprolific plants.
