Abstract

The mode of seed color inheritance in Capsicum was studied via an interspecific hybridization between C. pubescens Ruiz and Pav. (black seed color) and C. eximium Hunz. (yellow seed color). Black seed color was dominant over yellow seed color. The F(2) segregation pattern showed continuous variation. The generation means analysis indicated the presence of a significant effect of additive [d], dominance [h], and additive x additive [i] interaction for seed color inheritance. The estimate for a minimum number of effective factors (genes) involved in seed color inheritance was approximately 3.

摘要

通过毛辣椒（C. pubescens Ruiz and Pav.，种子颜色为黑色）和卓越辣椒（C. eximium Hunz.，种子颜色为黄色）之间的种间杂交，研究了辣椒种子颜色的遗传模式。黑色种子颜色对黄色种子颜色呈显性。F(2)分离模式表现出连续变异。世代均值分析表明，种子颜色遗传存在显著的加性效应[d]、显性效应[h]和加性×加性效应[i]。参与种子颜色遗传的有效因子（基因）的最小数量估计约为3个。
