摘要：

通过明确‘华双5R’和‘华油杂62R’2个抗根肿病油菜品种的田间抗性、农艺性状和产量情况，为油菜根肿病重发区筛选出优良的抗病品种。本研究在云南省西南地区的腾冲市、梁河县和临翔县3个油菜根肿病病区进行田间试验，采用本课题组研发品种和当地主推品种作为对照。田间试验结果显示，‘华双5R’和‘华油杂62R’在3个试验点均能正常成熟安全越冬，生育期176~199 d，各生育期表现整齐一致；‘华双5R’和‘华油杂62R’在腾冲和梁河点对油菜根肿病表现为高度抗病，在临翔点表现为抗病；‘华双5R’和‘华油杂62R’在3个试验点的农艺性状良好；‘华双5R’的产量在3个试验点与7个对照品种相比，比梁河点的‘云油杂12号’减产2.71%，与腾冲点的‘云油杂12号’和‘杂1256’、梁河点的‘云油杂15’和‘花油8号’、临翔点的‘云油杂12号’和‘德油1号’相比增产幅度为7.49%~56.83%；‘华油杂62R’的产量在3个试验点与7个对照品种相比，比梁河点的‘云油杂12号’减产5.76%，比临翔点的‘德油1号’减产4.61%，与腾冲点的‘云油杂12号’和‘杂1256’、梁河点的‘云油杂15’和‘花油8号’、临翔点的‘云油杂12号’相比增产幅度为4.12%~51.90%。‘华双5R’和‘华油杂62R’在3个试验点均能正常成熟，生育期176~199 d，对根肿病表现出较强抗性，同时农艺性状良好、产量较高，可在云南省西南地区油菜根肿病病区推广种植。

Abstract:

In this study, we clarified the field resistance, main agronomic traits and yield performance of ‘Huashuang 5R’ and ‘Huayouza 62R’, to screen out excellent disease-resistant varieties in the clubroot disease areas. Field experiments were carried out in three rape clubroot disease areas of Tengchong City, Lianghe County and Linxiang County in southwest Yunnan Province. And the varieties developed by our group and local main varieties were used as controls. The results of field experiments showed that the two clubroot-resistant varieties of ‘Huashuang 5R’ and ‘Huayouza 62R’ could mature normally and overwinter safely at the three test sites, with a growth period of 176-199 d, and the performance of each growth period was uniform. ‘Huashuang 5R’ and ‘Huayouza 62R’ showed high resistance to clubroot disease in Tengchong and Lianghe, and disease resistance in Linxiang. The agronomic traits of ‘Huashuang 5R’ and ‘Huayouza 62R’ were good in the three test sites. Compared with the seven control varieties in three test sites, the yield of ‘Huashuang 5R’ was reduced by 2.71% compared with ‘Yunyouza No.12’ in Lianghe; and the yield of ‘Huashuang 5R’ compared with ‘Yunyouza No.12’ and ‘Za 1256’ in Tengchong, ‘Yunyouza 15’ and ‘Huayou No.8’ in Lianghe, ‘Yunyouza No.12’ and ‘Deyou No.1’ in Linxiang was increased by 7.49% to 56.83%; the yield of ‘Huayouza 62R’ was 5.76% lower than that of ‘Yunyouza No.12’ in Lianghe, and was 4.61% lower than ‘Deyou No.1’ in Linxiang; and the yield of ‘Huayouza 62R’ compared with ‘Yunyouza No.12’ and ‘Za 1256’ in Tengchong, ‘Yunyouza 15’ and ‘Huayou No.8’ in Lianghe, ‘Yunyouza No.12’ in Linxiang was increased by 4.12% to 51.90%. ‘Huashuang 5R’ and ‘Huayouza 62R’ showed strong resistance to clubroot disease in the three test sites, with growth period of 176-199 d, and the agronomic traits and yields were normal compared to controls, and could be used as main cultivars in southwest Yunnan Province where clubroot disease was serious.
