大豆新品系的鉴定试验、品种比较试验及区域试验是大豆育种的三个重要环节,也是向生产推荐良种的三个重要“窗口”。根据准确的鉴定试验能够将量比较大的高代稳定品系准确而果断地取舍,准确的品种比较试验能为区域试验提供可靠的优良品系(做品比试验当年要设异地鉴定试验),准确的区域试验能为生产试验提供量极少而可靠的优良品系,从而为品种的审定推广提供可靠的试验数据。 Identification of soybean new line of testing, varieties of comparative experiments and regional trials of soybean breeding is an important part of three, but also to recommend the production of three important “window ”. Accurate identification test can accurately and decisively choose high-yielding stable strains with relatively large quantities. Accurate variety comparison tests can provide reliable and excellent strains for regional experiments Regional testing can provide very small and reliable quality lines for production testing, thus providing reliable test data for the validation of varieties.
