油菜粕 飼料化를 위한 有害成分(glucosinolate) 改良育種에 관한 硏究 Ⅲ. 3-butenyl 및 4-pentenylisothiocyanate 含量의 遺傳

Breeding for improvement of glucosinolate content in feed utilizability of rapeseed meal Ⅲ. The Inheritance of 3-butenyl, 4-pentenylisothiocyanate Content in Rapeseed Meal

To obtain the basic information for improving the quality of rapeseed meals, the inheritance of 3-butenly-isothiocyanate and 4-pentenylisothiocyanate content was estimated in the study of reciprocal crosses among the low glucosinolate Korean variety Youngsan and 3 other high glucosinolate varieties. The segregation ratio of 3-butenylisothiocyanate content was fitted to the ratio of 63:1, and the low 3-butenylisothiocyanate content of seed meal was considered to be controlled by three pairs of recessive genes. The low 4-pentenylisothiocyanate content of seed meal would be controlled by four pairs of recessive genes. The inheritance of 3-butenyl and 4-pentenylisothiocyanate content were influenced by the cytoplasm. The cytoplasmic influence was also detected in the inheritance of 3 butenyl and 4-pentenylisothiocyanate content.
