本文分析了1984—1986年度种植于长江下游地区7个地点的10个小麦品种的产量资料,研究选育和鉴定广泛适应性小麦品种的合适地点.结果表明,在小麦新品种选育过程中出现了不同程度的特殊适应性.扬州点是选育兼具高产、适应性广的小麦品种的合适场所.没有任何单个地点或二地点组合符合选择理想测试点的4个指标,长江下游地区小麦品种区域试验至少应在3个地点进行.
In this paper, the yield data of 10 wheat cultivars planted in 7 locations in the lower reaches of the Yangtze River from 1984 to 1986 were analyzed, and the suitable sites for breeding and identifying a wide range of adaptive wheat cultivars were studied.The results showed that during the breeding of new wheat varieties, Yangzhou point is a suitable place to breed wheat varieties with high yield and wide adaptability.No any single place or combination of two places can meet the four indexes to choose the ideal test point.The wheat varieties in the lower reaches of the Yangtze River Regional trials should be conducted at a minimum of 3 locations.
