摘　　要：采用常规高产稳产分析方法,结合高稳系数法,对2018年江苏省耐盐水稻联合体14个参试品种的高产稳产性能进行分析比较。结果表明,NYJ7012、扬农粳3284、连鉴7号3个参试品种在丰产性和稳产性方面表现都很优异,适宜在江苏省大部沿海滩涂地区种植推广;通海粳17-2、盐稻1640、盐稻178、盐稻1367、华丰16135、盐稻1382这6个参试品种在所有参试品种中产量靠前、稳产性参数排名一般,对种植环境敏感,在有利的条件下可获得高产,建议结合各试点具体情况,在适合的地区推广种植,以充分发挥其产量优势。The present study compared 14 salt-tolerant rice varieties of Jiangsu Salt-tolerant Rice Association with respect to their yielding ability and yield stability in field trials performed at six sites in Jiangsu Province in 2018.Their yielding capacities and yield stability were analyzed and compared by using the conventional high and stable yield analysis method and high stability coefficient method.The results showed that the three tested varieties NYJ7012(P1),Yangnongjing 3284(P9),and Lianjian 7(P5)had excellent performance in yielding ability and yield stability;therefore,they are suitable for cultivation and promotion in most tidal flat areas of Jiangsu Province.On the other hand,the six tested varieties Tonghaijing 17-2(P6),Yandao 1640(P10),Yandao 178(P12),Yandao1367(P8),Huafeng 16135(P7),and Yandao 1382(P11)had the highest yields among all tested varieties,while their parameters of yield stability were ranked at moderate levels,and they are sensitive to the planting environment.This suggests that the six varieties can achieve a high yield under favorable environmental conditions,so we recommend that they should be promoted and planted in areas with environmental conditions suitable for their growth,thus giving full play to their yield advantages.
