Genetic Effects on Corn Seed Longevity

This study aimed to elucidate the maternal and paternal genetic effects of physiological quality hybrid seed corn over time, as well contribution heterosis for this trait. The seeds single hybrids, reciprocals parents were obtained by manual crosses in a complete diallel cross scheme. analyses germination accelerated aging performed data analyzed with Tukey test Griffing method. quadratic components general combining ability similar specific superior reciprocal, most evaluation periods, implying that on characters attributed genes additive effect non-additive effect. longevity was highly significant however its smaller than effects, but proved be important combinations lower estimate ability.
