冬小麦新品种山农辐63是经Co~(60)γ射线处理“蚰包×欧柔”F_4干种子选育而成。经测产、品比、示范和大田生产试验,增产显著,适应性广,改进了抗病性,从而提高了丰产稳产特性,适合在中等肥力和上等肥力麦田种植,被列为山东省冬小麦推广品种。该品种和其它品种比较,它的主要特点是:千粒重高且较稳定;灌浆速度快;叶片的光合性能良好,“穗叶比值”大;栽培时用肥经济,经济系数高。辐射选育高产小麦品种应注意:(1)要选用综合性状较好,适应性能较强的丰产材料作为辐射育种的亲本。(2)对M_1代要进行选择,尤其是抗病性选择。(3)矮秆突变体应选70—85厘米的半矮秆型。
The new winter wheat cultivar Shannongjia 63 is bred by the Co ~ (60) γ-ray treatment “Xun Bao × Ou Rou” F_4 dry seeds. The test of production, product ratio, demonstration and field production test, significant yield, wide adaptability, improved disease resistance, thereby enhancing the characteristics of high yield and stability, suitable for medium fertility and superior fertility in wheat fields, was listed as winter wheat in Shandong Province Promotion of varieties. Compared with other varieties, the main features of this variety are: high and stable grain weight of one thousand grain; fast filling speed; good photosynthetic performance of leaves and large “ratio of ear and leaf”; economic use of fertilizer and high economic coefficient during cultivation. Radiation breeding high-yielding wheat varieties should pay attention to: (1) to choose a good comprehensive traits, adaptability strong yielding materials as the parent of radiation breeding. (2) Choose the M_1 generation, especially the disease resistance. (3) dwarf mutants should be selected 70-85 cm semi-dwarf type.
