春秋两用型结球甘蓝新品种YR绿金刚的选育

Breeding of a new cabbage cultivar YR Lüjingang for growing in spring and autumn

摘要

YR绿金刚是以细胞质雄性不育系CMS02C34为母本、自交系10C313为父本配制而成的春秋两用型结球甘蓝杂交1代品种。该品种适宜北京、河北等地区春秋季露地种植，中熟，从定植到始收55~60 d；株型半直立，株高约32.7 cm, 开展度约53.1 cm；叶球圆球形，球色绿，横径约18.3 cm, 纵径约17.9 cm, 中心柱短、叶色黄绿、结球紧实、蜡粉中多，单球质量约1.5 kg。该品种商品性好，耐裂球，耐先期抽薹，抗枯萎病和黑腐病，脚高、耐雨水，667 m²产量约5 858.17 kg。2022年9月通过农业农村部非主要农作物品种登记。

Abstract

YR Lüjingang is a spring and autumn cabbage F1 hybrid developed by using the male sterile line CMS02C34 as the female parent and the inbred line 10C313 as the male parent. It is suitable for open-field cultivation in spring and autumn in Beijing, Hebei and other regions. This cultivar is medium maturing, taking 55-60 d from planting to harvest. The plant type is semi-erect, the plant height is about 32.7 cm, the spreading degree is about 53.1 cm, the transverse diameter is about 18.3 cm, the longitudinal diameter is about 17.9 cm, the central column is short, the leaf color is yellow and green, the ball is firm, round and spherical, the ball color is green, the single ball mass is about 1.5 kg. This cultivar has good marketability, exhibiting resistance to cracking, early bolting, as well as resistance to wilt and black rot diseases. It has a high stalk position, making it resistant to rainwater. The yield is approximately 5 858.17 kg per 667 m².
