培育和推广低芥酸和低硫代葡萄糖苷油菜新品种.是我国“七五”农业重大科技攻关项目之一;也是现阶段提高我国菜油的食用营养价值的主要途径。这对满足国内外市场的需要,促进油菜商品化生产的发展,具有重要意义。我省油菜常年面积和总产量均居全国第二位,油菜籽的商品率高,发展低芥酸油菜有着巨大的潜力。“六五”以来,我省各育种单位培育出了一些低芥酸油菜新品种(系),为了解这些品种(系)在各试点产量间的差异显著性,在不同试点所表现的差异显著性和适宜种植范围,以及品种(系)对不同年份的环境因素影响的适应性,本文对此进行分析,为品种审定和应用提供理论依据。
Cultivation and promotion of low erucic acid and low glucosinolate rapeseed new varieties is one of China’s “Seventh Five-Year” major agricultural science and technology projects; is also the main way to improve the edible nutritional value of our country vegetable oil. This is of great significance to meeting the needs of domestic and foreign markets and promoting the commercialization of rapeseed production. Rapeseed perennial area and total output rank second in the country, rapeseed high commodity rate, the development of low erucic rape has great potential. Since the Sixth Five-Year Plan, some breeding units of low erucic acid rape have been bred in various breeding units in our province. In order to understand the significant difference among the pilot cultivars of these varieties (lines), the differences among the different experimental plots are significant Sexual and appropriate planting range, as well as the adaptability of varieties (lines) to different environmental factors in different years. This article analyzes this and provides a theoretical basis for the validation and application of varieties.
