摘要
为筛选高产、抗病,适合福建省夏秋季栽培的不结球白菜品种。以福建省不结球白菜主栽品种金品1夏、黑玫瑰、夏绿妃为对照,对福州市蔬菜科学研究所选育的3个不结球白菜组合(123、226、227)进行品种比较试验,考察不结球白菜新组合的农艺性状、产量和抗病性,并通过实验室进行苗期软腐病、黑腐病的抗性鉴定试验。结果表明:不结球白菜组合123、226、227折合每667 m^2产量分别为1 561、1 774、1 808 kg,产量较对照金品1夏、黑玫瑰、夏绿妃具有一定的优势或相当;综合性状表现较好,其叶片叶柄比分别比对照金品1夏、黑玫瑰、夏绿妃更接近黄金比例1∶1,叶片较宽且厚实,束腰性、抗病性强。在室内抗病性鉴定试验中,组合123、226、227软腐病病情指数分别为39.26、79.26、72.59,黑腐病病情指数分别为49.44、48.33、41.1,表现比对照金品1夏、黑玫瑰和夏绿妃更抗病。综上所述,不结球白菜新组合123、226、227商品性好、抗病、高产,可作为夏秋品种在福建省推广种植。
In order to screen out the high-yield and disease-resistant varieties of non-heading Chinese cabbage that were suitable for summer and autumn cultivation in Fujian Province,by taking the main cultivars of non-heading Chinese cabbage in Fujian,namely Jinpin 1 xia,Black rose and Xialvfei as the control,a variety comparative experiment was carried out on 3 combinations(123,226,227)of non-heading Chinese cabbage bred by Fuzhou Institute of Vegetable Science,in order to investigate the agronomic characters,yield and disease resistance of the new combinations of non-heading Chinese cabbage.And the resistance identification tests of soft rot and black rot at the seedling stage were also carried out in the laboratory.The results showed that the yield of the combinations(123,226,227)of non-heading Chinese cabbage was 1 561,1 774,1 808 kg per 667 m^2 respectively,which had certain advantages or was equivalent to that of the control group,namely Jinpin 1 xia,Black rose and Xialvfei.The comprehensive characters were better,and the ratio of leaf to petiole was closer to the golden ratio of 1∶1 than that of the control group,namely Jinpin 1 xia,Black rose and Xialvfei,with wide and thick leaves,and strong disease resistance.In the indoor disease resistance identification test,the disease index of soft rot in the combination of 123,226,227 was respectively 39.26,79.26 and 72.59,while the disease index of black rot was respectively 49.44,48.33 and 41.1,which showed better disease resistance than the control group,namely Jinpin 1 xia,Black rose and Xialvfei.In conclusion,the new combinations(123,226,227)of non-heading Chinese cabbage had good commercial characteistics,disease resistance and high yield,which could be promoted as the varieties for summer and autumn cultivation in Fujian Province.
