| Abstract: |
| The protein and fat contents of 22 main cultivars of walnut in Yunnan were determined, and the fatty acid compositions of the extracted oils were determined by gas chromatography. The results showed that the average protein content of the 22 main cultivars of walnut in Yunnan was 14.25%,overall meeting the national Ⅲ level standard. The protein content of ‘Huaning white shell’ was the highest, reaching 21.21%, and the protein content of ‘Shengyong’ was the lowest, reaching 10.93%. The fat content of the 22 main cultivars of walnut in Yunnan was 59.40%-69.86%,and the coefficient of variation was 3.87%. Principal component analysis of fatty acid showed that the comprehensive score of ‘Yangza 1’ was the highest,while the ‘Niangqing’ was the lowest.Through cluster analysis,cultivars with high protein content included‘Wanlong’‘Honghe 2’‘Yuanboluo’ and ‘Huaning white shell’, and cultivars with high linolenic acid and linoleic acid contents included ‘Yangzaoxiang’‘Huaning white shell’‘Xixiang’‘Ningxiang’‘False tea’‘Yuanboluo’‘Yangza 1’and‘Jianfeng’. |
