FLOWERING, YIELD AND SEED QUALITY IN POTATO GENOTYPES

In Chapingo, Mexico, two evaluations of potato genotypes were carried out in different years with the purpose of knowing the behavior of flowering and sexual seed production, and to determine the physiological quality of recently harvested seed. Number of flowers per plant, pollen viability, fruit set, and number of mature berries per plant varied widely among genotypes. Only between 10 and 31 % of genotypes, en each year of testing, had seed yields from 9 to 139 kg·ha-1, where cv. Tollocan was outstanding in seed number per berry and weight of 100 seeds were 242 and 32 mg, respectively. Due to dormancy, recently harvested seed only reached 79 and 72 % germination, respectively. Best seed physiological quality was shown by genotypes ‘San Jose’, ‘Greta’, ‘Tollocan’, ‘C-171836’, and ‘C-575049’.
