广西第十周期夏大豆区试品种评价

通过试验,鉴定各供试种的区域适应性、经济性状、抗性反应、增产潜力等表现,评选出比对照种“桂夏1号”高产、优质、抗逆性强、适应性广的夏大豆品种。为评审和推广应用提供科学依据。2009—2011年连续三年,每年一季,其中两年区域试验,一年生产试验。区域试验：每个区试点统一采用随机区组排列方法,三次重复,小区面积6．67m^2,所得产量采用“T”法测定显著性,并采用中国农业大学“区试99”统计软件对各参试种产量进行联合方差分析;生产试验：试验采用小区顺序排列,不设重复,小区面积133．34m^2,成熟时全区收获计产。2009—2011年,广西第十周期夏大豆区试结果表明,桂345、华夏6号和桂319三个品种的产量及综合性状较优。通过广西大豆区试。可供广西各地引种试种。

Evaluation on summer soybean varieties tested in the 10th regional experiment of Guangxi

By means of experiments, to identify the regional adaptability, economic characters, resistance reaction and yield-increase potential etc., and to select better summer soybean varieties than the CK （Guixia No.1 ） from the tested varieties, which will provide scientific basis for evaluation and extension, three years＂ experiments 2009-2011, one season for each year, among them, two years＂ reginal experiments, one year production experiment. Regional experiment： randomized block arrangement method would be used with three repeats, 6.67m^2 for each plot, the yields would be tested for identify significance by ＂T＂ method, and complex variance analysis would be applied on yields by statistical software ＂regional experiment 99＂. Production experiment： plot seriation method would be used without repeats, plot area of 133.34m^2 , total plots yield-measuring when harvesting at mature. the results of the 10 th period summer soybean regional experiment show that Gui 345, Huaxia No.6, Gui 319 have the better integrated characters than CK , and can be cultured experimentally in all regions of Guangxi.
