Abstract

Abstract:

【Objective】To explore the ecological adaptability of breeding new varieties/lines with strong cold resistance and the feasibility of northward migration of Brassica napus (Brassica napus L.) at high altitude and high latitude, so as to realize the replacement of inferior and inefficient winter rape varieties, farmland ecological improvement and industrial promotion.【Method】Ten cold-resistant winter rape lines of Brassica napus were used as materials, and the original planting area and typical northward migration ecological region of winter rape of Brassica napus were selected as experiments to study the changes of growth period, yield, quality, plant type and other characters of cold-resistant winter rape varieties of Brassica napus in cold and cool areas at high latitude and high altitude.【Result】The results showed that Brassica napus-type winter rape could survive the winter safely in the original planting area (Tianshui), and the over-wintering rate of Brassica napus decreased obviously after moving northward. The control varieties（Ganza 1）could not survive the winter normally in the northward migration area (Baiyin and Dingxi); The 10 strong cold-resistant varieties could survive the winter safely in the Baiyin pilot, and the over-wintering rate was between 81% and 94%; The Dingxi pilot, the over-wintering rate was between 51% and 88%, of which 6 strong cold-resistant varieties could survive the winter safely in Dingxi (≥75%). The growth period of Brassica napus was prolonged by 52 days and 70 days after moving northward; The yield of cold-resistant lines move northward to Baiyin varied from-11.05% to 44.67%, and the highest yield was 5 170.80 kg·hm^-2 .The yield of all the tested lines in Baiyin decreased significantly, and the highest yield was 3 392.85 kg·hm^-2 .After planting northward, the plant height, branching position decreased, the secondary branch increased, the plant type became worse, the number of pods per plant decreased, the number of pods and 1000-grain weight increased, and the characters of pods became better. After moving northward, the contents of oil and glucosinolates in Brassica napus decreased, while the contents of erucic acid increased. One of the tested lines/species was a double-low, high-quality and strong cold-resistant strain (16NS20H1), and the other was a cold-resistant variety with low erucic acid (Ganza 1). Correlation analysis showed that overwintering rate, yield, plant height, branch position, main inflorescence length, oil content and glucosinolate content were significantly negatively correlated with altitude and latitude. It was positively correlated with annual average temperature, frost-free days and coldest monthly temperature, while the growth period, secondary branches changed to the contrary. In the northward moving area, the lodging resistance of Brassica napus type was significantly better than that of Brassica campestris L.. 【Conclusion】The cold resistance of the new cold-resistant winter rape strain of Brassica napus was obviously stronger than that of the control (Ganza 1), and it could survive the winter safely in the area of 36°12'N latitude and 2 248 m above sea level, and the winter rape lines with high yield, high quality and strong cold resistance could be selected and improve the yield level, quality and nutritional value of winter rape in the strong winter region of North China.
