广西第十一周期夏大豆区试概况及参试品种评价

General situation of regional trials and evaluation of testing varieties for the 11th period summer soybean cultivation in Guangxi

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。设7个试点,三年试验,时间从2012-2014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6.67m2;生产试验:试验采用小区顺序排列,不设重复,小区面积133.34m2。鉴定桂103、桂166、桂252、桂11-1、桂11-2、桂11-3、桂11-4、粤夏2011-3、粤夏2011-4、粤夏2011-5和华严0926等品系(种)的小区产量,生育期,株高等性状,辅以软件分析,确定它们的丰产性、稳定性、适应性等。广西第十一周期(2012-2014)夏大豆区域试验结果表明,11个参试种中,粤夏2011-4,桂11-4,桂166,粤夏2011-3和桂252五个品种的综合性状均优于对照种"桂夏1号",通过广西夏大豆区试。可供广西各地引种、试种示范和推广。

The regional trial selected the varieties with characteristics of higher yield, better quality, stronger resistence and wider adaptability than＂Guixia 1＂, according to the agronomic traits of different trial areas.ar-range trails in 7 test points for one cycle of three years （2012-2014）, including two years regional test and one year production test. Regional test：applying randomized block arrangement with three repeats, each residen-tial area is 6.67m2; Production test： applying the residential order, one repeat, every residential area is 133.34m2. Tested Gui 103, Gui 166, Gui 252, Gui 11-1, Gui 11-2, Gui 11-3, Gui 11-4,Yuexia 2011-3, Yuexia 2011-4 and Yuexia 2011-5, Huayan 0926 evaluation their potential yield, economic characters, re-sistance reaction, regional adaptive performance, selected the varieties with higher yield, better quality, stronger resistence and wider adaptability than ＂Guixia 1＂, Among the eleven tested varieties, Yuexia 2011-4, Gui 11-4, Gui 166, Yuexia 2011-3,and Gui 252 were outstanding compared with the CK in agro-nomic traits. Therefore, they are applicable to be extended and demonstrated in all regions of Guangxi.
