杂交水稻新品种D优3138的丰产稳产及适应性

为D优3138杂交水稻新品种的推广应用提供参考,根据2011-2015年河南省豫南稻区区域试验、生产试验及高产栽培试验结果,利用DPS数据处理系统中品种区域试验统计方法对D优3138杂交水稻新品种的丰产性、稳产性及适应性进行分析。结果表明:D优3138在2011-2013年河南省豫南稻区区域试验和生产试验中的平均产量为8 620.0kg/hm~2,在2014-2015年高产栽培试验中的平均产量为10 210kg/hm~2,平均高稳系数(88.74%)和适应度(83.4%)均高于Ⅱ优838(CK)。在区域试验的8个试点中,2011年D优3138产量超过所有组合平均产量的试点有5个,CK为3个;2012年超过所有组合平均产量的试点有7个,CK仅1个;在2013年生产试验的8个试点中,D优3138在各试点的产量均超过所有组合的平均产量,而CK在各试点的产量均低于各组合的平均产量。因此,D优3138的种植区域及适应范围广、丰产稳产性好,可在豫南稻区大面积推广应用。

High-yield Stability and Adaptability of D You 3138, a New Hybrid Rice Cultivar

To provide references for the popularization and application of the new hybrid rice cultivar D You 3138, according to the results of regional tests, production tests and high-yield cultivation tests in southwestern Henan rice area during 2011-2015, the yielding ability, stability and adaptability of D You 3138 were analyzed by using DPS data processing system.Results: Yield of D you 3138 was 8 620.0 kg/hm2 in the regional test and production test in southwestern Henan during 2011-2013, the average yield of which was 10 210 kg/hm2 during 2014-2015.The average high-stable coefficient(88.74%)and fitness(83.4%) were all higher than ⅡYou 838(CK).In the eight test sites of regional test, the yields of D You 3138 in five test sites were higher than the mean yield of all combinations, and three for CK;In regional test in 2012, seven for D You 3138 and one for CK;In production test in 2013, eight for D You 3138 and zero for CK.Consequently, it can be concluded that D You 3138 is of a wide accommodation, good yielding ability and stability, which can be widely popularized and applied in southwestern Henan.
