大豆新品种合丰47产量评价与分析

Yield Evaluation and Analysis of New Soybean rariety Hefeng47

利用AMMI模型对大豆新品种合丰47号参加黑龙江省大豆区域试验第二积温带三江平原西南温和半湿润区(5区)试验结果进行分析,结果表明:合丰47号产量在所有参试品种中列第1位;(Di)值在参试品种中列第2位,小于对照品种合丰35号的(Di)值,表明合丰47号的适应性好于对照品种合丰35号;从品种与试验点的交互作用可以看出,合丰47号适于在黑龙江省第二积温带三江平原西南温和半湿润区的汤原、桦南、富锦、友谊、笔架山、依兰等地区推广。采用逐步回归法获得合丰47号的产量回归方程为:Y=4056.6248-39.1945X1+14.4335X4+38.9511X6+37.42421X7。表明有效分枝对合丰47号的产量影响最大,其次是平方米株数和百粒重。

AMMI model was used to analyze the result of Hefeng47 that attended soybean regional trials in the second accumulated temperature belt of Heilongjiang province and southwest temperature Sanjiang Plain sub-humid zone （five zones）. The result indicated that the yield of Hefeng47 was the first among all the varieties used in trail, while Di value of Hefeng47 was the second and lower than the check. Hefeng 35 Therefore the adaptability of Hefeng47 was superior to Hefeng35. According to the interaction of variety and experiment places, Hefeng47 was suitable to promote to grow in the second accumulated temperature belt of Heilongjiang province and southwest temperature Sanjiang Plain sub-humid zone （five zones）, including Tangyuan, Huanan, Fujin, Youyi, Bijia mountain, Yilan and et al. Stepwise regression method was adopted to obtain the yield regression equation for Hefeng47 which was： Y=4056.6248-39.1945X1＋14.4335X4 ＋ 38.9511X6＋37.42421X7.It showed that effective branchy stem contributed most to the yield of Hefeng47, following by the number of plants per square, lastly the weight of one hundred seeds.
