新麦9813在黄淮冬麦区的高产稳产性与广适性评价OA

To comprehensively evaluate the yield potential of the new wheat variety Xinmai 9813,this study systematically analyzed its yield performance,high-stability coefficient,coefficient of variation and adaptability based on data from the regional trials of the irrigated group in the southern part of the Huang-Huai winter wheat region under the national joint test program for winter wheat varieties during 2020-2022,as well as the production trial data collected in 2022-2023.The results showed that Xinmai 9813 achieved significant(p<0.05)yield increases compared with the control variety Zhoumai 36(secondary control:Zhoumai 18).The average yield of Xinmai 9813 in the two-year regional trials reached 9 054.0 kg·hm-2,representing a 6.54%yield increase over Zhoumai 18 and a 4.82%increase over Zhoumai 36.In the production trial,its average yield was 8 638.5 kg·hm-2,6.97%higher than Zhoumai 36,with a 100%yield-increasing test site rate.Moreover,this variety possessed excellent agronomic traits,strong lodging resistance,medium-gluten grain quality,and wide adaptability.It is concluded that Xinmai 9813 is an elite wheat variety suitable for popularization in the southern part of the Huang-Huai winter wheat region.
