Study of variability for yield components in some popcorn (Zea mays, var. Everfa) genotypes
Keywords:
popcorn, ear traitsAbstract
The objective of this study was to evaluate genetic variability based on the ear traits of 5 genotype popcorn (Zea mays var. everta) to be used in breeding programs. The genotype with the largest ear diameter was Pc3 (34.07mm), and the smallest ear diameter was recorded at Pc4 (31.37mm). The genotype with the highest number of grains per ear was Pc4 (326.52). The weight of the ear was 75.54 (g) and three of the genotypes exceeded the average weight for this character (Pc1, Pc2, Pc4). The genotypes with the highest percentage of grains per cob were Pc4 and Pc5. Based on ear traits, genotypes Pc4 and Pc5 showed 90% similarity and were located in the same cluster as genotype Pc1, which showed 80% similarity with them.
