영문 초록

This study was performed to obtain basic informations for breeding early maturing varieties in red pepper. Eight parent varieties and twenty eight diallel crosses between them were used as materials. Heterosis and heterobeltiosis for main stem length, branch length, plant height and main stem diameter, corelations between 4 plant height characters and corelations between plant height characters and days to first flower were investigated. From the analysis of variance, the 1% level significances were observed among parents and F₁s in main stem length, branch length, plant height and main stem diameter. The means of F₁s were significantly longer than those of parents in all plant height characters. Degree and direction of heterosis and heterobeltiosis varied greatly with different crosses and most of F₁ hybrids showed positive partial dominace or over dominance in all plant height characters. Average degree of dominance for main stem length and branch length were partial dominant and those for plant height and main stem diameter were almost complete dominant. In F₁ hybrids, positively significant corelations between main stem length, branch length, plant height, main stem diameter and days to first flower were observed except between main stem length and branch length and between branch length and days to first flower. Highly significant corelations between mid - parents and F₁ hybrids were observed in all plant height characters.
