Abstract

Abstract:

Three Brassica napus L. varieties, ‘Dadi 95’, ‘Jinghua 165’, and ‘Shanyou 2’, were used as materials to analyze the effects of different altitudes on agronomic and quality traits of rapeseed. The results showed that: with the increase of altitude, the whole growth period of rapeseed was prolonged, the plant height, branch height, number of branches, number of siliques per plant and number of seeds per silique decreased, so did the yield per plant and yield, while the thousand-grain weight increased; the protein content decreased and oil content increased, and the content of glucosinolate and erucic acid showed inconsistence among different varieties. Correlation analysis showed that the altitude was significantly and positively correlated with the growth period, and significantly and negatively correlated with the plant height and yield per plant, the correlation coefficient was 0.519, -0.548, and -0.528 respectively; the altitude was significantly and negatively correlated with the protein content, and positively correlated with the content of oil, glucosinolates and erucic acid, the correlation coefficient was -0.590, 0.262, 0.161, and 0.138, respectively.

Key words: altitude, Brassica napus L, agronomic traits, quality traits, correlation analysis
