Abstract:In order to screen pea varieties which are suitable for planting in upland red soil in Jiangxi, 8 pea varieties were used as materials in this study to analyze the growth indexes such as fresh pod weight and plant height, and the nutritional indexes of erusic-acid, glucosinolate, protein, moisture and oleic acid, then combined with the method of membership function values, the adaptability of different pea varieties were evaluated. The results showed that in terms of growth indexes, Ningwan variety had highest fresh pod yield (7 299.94 kg/hm2), followed by the varieties of Zitiancui, Zhongwan 6 and Zhongwan 11 (6 336.50-6 929.39 kg/hm2). Taiwan-Qizhen 76 variety had the highest plant height (1.48 m), while Ningwan pea and Zhongwan 6 varieties had the moderate ones (1.15 and 1.13 m, respectively). In terms of nutritional indexes, Zitiansui variety had the highest protein content (26.60%), Hanyi 402 variety had the highest moisture content (11.17%), Biyu variety had the lowest glucosinolate content(25.49%), Ningwan variety had the lowest erusic-acid content (0.39%), Taiwan-Qizhen 76 variety had the highest oleic acid content (34.02%). Correlation analysis showed that fresh pod yield was significantly negatively correlated with erucic-acid and moisture (P<0.05), but had no correlation with other nutritional indexes. Further analysis of membership function showed that the comprehensive performance of Taiwan-Qizhen 76 variety was the best, followed by Zhongwan 6 and Hanyi 402 varieties, which are suitable for planting in Jinagxi upland red soil.
