摘要:

研究旨在筛选耐湿性较强的甘蓝型油菜品种,为四川及其他稻-油轮作模式地区推广优质、耐湿油菜品种提供依据。试验以川、渝、云主推的甘蓝型油菜品种‘川油36’、‘川油46’、‘川油83’、‘川早油1号’、‘渝油35’和‘春喜1402’为试验材料,通过室内淹水培养3、5、7 d分别模拟不同湿害程度下的田间环境,研究苗期各油菜品种对不同湿害环境的响应。结果表明,综合湿害指数与发芽率和苗鲜重呈显著正相关,与主根长和株高相关性不显著;甘蓝型油菜苗期耐湿性表现为‘川油83’>‘渝油35’>‘春喜1402’>‘川油36’>‘川早油1号’>‘川油46’。综上,甘蓝型油菜苗期的耐湿性可通过发芽率和苗鲜重判定;甘蓝型油菜苗期综合湿害指数可直接用于评价其抵御湿害胁迫的能力;本试验筛选出苗期耐湿性较强的甘蓝型油菜品种为‘川油83’。

Abstract:

The paper aims to screen out the varieties of Brassica napus with waterlogging tolerance, to provide a basis for high-quality and moisture-resistant rapeseed varieties in Sichuan and other rice-oil rotation mode areas. In this experiment, the B. napus varieties ‘Chuanyou 36’, ‘Chuanyou 46’, ‘Chuanyou 83’, ‘Chuanzaoyou 1’, ‘Yuyou 35’and ‘Chunxi 1402’, which were mainly promoted in Sichuan, Chongqing and Yunnan, were used as experimental materials. Indoor water flooding culture was carried out for 3, 5 and 7 days to simulate the field environment under different degrees of waterlogging stress, to study the response of B. napus varieties to different wet damage environments at seedling stage. It was found that the comprehensive wet-damage index was positively correlated with germination rate and fresh weight of seedlings, but not with the length of main roots and plant height. The waterlogging tolerance of various B. napus varieties at seedling stage was ‘Chuanyou 83’> ‘Yuyou 35’> ‘Chunxi 1402’> ‘Chuanyou 36’>‘Chuanzaoyou 1’> ‘Chuanyou 46’. To sum up, the B. napus with waterlogging tolerance at seedling stage can be determined by germination rate and fresh weight of seedlings, and the comprehensive wet-damage index can be directly used to evaluate its waterlogging tolerance. ‘Chuanyou 83’, a B. napus variety with strong waterlogging tolerance, was selected at seedling stage in this experiment.
