This study was performed to obtain the basic informations on days to first flower in red pepper. Eight parent varieties and twenty eight F₁ hybrids from 8X8 half diallel cross were used as the materials, and heterosis, combining ability, the degree and direction of dominance, and heritability were evaluated.
The 1% significances in day to first flower were observed among parents and F₁s, and the mean of F₁s was not significantly longer than parents.
Positive and negative heterosis and heterobeltiosis were observed. Both average heterosis and heterobeltiosis were negative.
General combining ability (GCA) and specific combining ability (SCA) variances were highly significant, and GCA variances were greater than SCA variances.
Partial dominance was observed in days to first flower and the direction of dominance was negative excluding Chunan and Saegochu varieties.
The number of effective gene was estimated as one, and heritabilities in narrow and broad sense were fairly high.
