재래종과 Orient종 연초 $F_2$세대의 양적 형질에 대한 유전분석

GENETIC ANALYSIS OF QUANTITATIVE CHARACTERS IN $F_2$ POPULATIONS OF KOREA LOCAL AND ORIENTAL TOBACCO VARIETIES (N. TABACUM L.)

In order to obtain the basic information for the successful breeding of aromatic tobacco (N. tabacum L.), the combining ability and the mode of inheritance in 28 $F_2$ hybrids by diallel crosses between Korea local and oriental varieties were investigated. Estimates of general combining ability were significant for all characters investigated, and the specific combining ability was significant for stalk height, leaves per plant, leaf length, leaf width and days to flower. The partial dominance was exhibited by all characters investigated as well as additive effects were larger than dominance effects for all characters.
