- 摘要:
- 抗根肿病中晚熟大白菜‘辽白23’是由抗根肿病高代自交不亲和系S5-1和78S6-2配制而成的一代杂种。生育期约79 d,植株直立,株高47.5 cm,开展度61.9 cm,外叶绿,叶柄绿色,内叶黄色,叶球筒形叠抱,球高35.7 cm,球粗16.9 cm。单球净菜质量约3.5 kg,每667 m2净菜产量约7 900 kg。分子标记鉴定抗病性表明‘辽白23’含有CRa、CRb 2个根肿病抗性基因,抗根肿病、病毒病、霜霉病、软腐病。适宜在辽宁、山东、吉林、黑龙江等地种植。
- Abstract:
- ‘Liaobai 23’ is a new mid-late maturing Chinese cabbage F1 hybrid with resistance to clubroot disease developed by crossing self-incompatible line S5-1 with 78S6-2 with resistance to clubroot disease.It takes 79 days from sowing to harvest.Its plant type is erect,the plant is about 47.5 cm in height and 61.9 cm in width with green outer-leaves and green petiole.The head center leaves are yellow in color.Its leaf balls are of cylinder-shaped and overlapping type with about 35.7 cm in height and 16.9 cm in diameter.The average head weight is about 3.5 kg,and the yield is about 7 900 kg per 667 m2.Molecular marker analysis showed that ‘Liaobai 23’ contained CRa and CRb two resistant genes to clubroot.It′s resistant to clubroot disease,TuMV,downy mildew and soft rot.It is suitable to be cultivated in Liaoning,Shandong,Jilin and Heilongjiang.
