高产稳产抗病冬小麦新品种豫麦39号的选育

The Breeding of a New Winter Wheat Variety “Yumai 39”Characterized by High and Stable Yield and Disease Resistance

利用早熟大穗品种偃师４号与抗病、灌浆快的大粒品种陕农７８５９杂交，通过协调穗粒数与千粒重的矛盾，保持适中的成穗数，确定合理的株型模式，选育成高产、稳产、抗病、落黄好、灌浆快且具有广泛适应性的多穗大粒型冬小麦新品种豫麦３９号。

Using the varieties of “Yanshi 4” characterized by early ripening and big spikes and “shaannong 7859”characterized by disease resistance,fast kernel filling and big kernels as the crossing parents,through coordinating the contridiction between number of kernels per spike and weight of 1000 kernels,maintaining adequate number of spikes,establishing a reasonable plant morphological model,we have successfully developed a new multi spike and big kernel type winter wheat variety“Yumai 39”which has the characteristics of high and stable yield,disease resistance,good yellowing,fast kernel filling and extensive adapation.
