二面交雜에 依한 고추果重의 構成要素에 對한 遺傳分析 = Diallel Analysis of Anatomical Components of the Fruit in Red Pepper

다국어 초록 (Multilingual Abstract)

This study was performed to obtain the basic informations for red dry pepper fruit with more pericarp weight(or in percentage) with a complete diallel cross(excluding reciprocals) using eight cultivars. Heterosis, combining ability and inheritance of the dry red fruit weight and its components(stem, placenta, seed, and pericarp) were evaluated. The results obtained were summarized as follows :
Dry weight / fruit and its four antomical components were heavier in the earlier harvest fruit than in that of the later fruit. They showed 1% significance among parents and F_(1)s, and those of F_(1) were significantly heavier than in parent. All characters in earlier fruit of parent, however, were higher than in later fruit of F_(1).
Dry weight percentage of pericarp to dry weight / fruit was highest followed by seed. Percentage of pericarp in the later fruit was increased while the seed decreased and percentages of stem and placenta were not differed between the earlier and later fruit.
F_(1) hybrids above the higher parent were observed in all characters. Mean heterosis (%) was positive in all characters while mean heterobeltiosis (%) was negative excepting seed and dry weight / fruit.
GCA and SCA variances were highly significant, and GCA vaiances were greater than SCA in all characters.
The directions of dominance were positive. Partial dominance was shown in stem, complete dominance in placenta, pericarp and dry weight / fruti, and over dominance in seed.
The effective genes were estimated as one for stem and placenta, and two for seed, pericarp and dry weight / fruit. Heritabilities in narrow and broad sense were higher.
