晋春13号春小麦新品种的选育

Breeding of a New Spring Wheat Variety, Jinchun N0. 13

晋春13号是利用太谷核不育小麦与小偃麦亚远缘杂交选育而成的第一个春小麦品种，其遗传基础丰富，具有高产、优质、抗病、适应性广等优点。3年省区试产量居首位，多点示范产量5250-6000kg／hm，比晋春9号增产20％－22％。1997年北方区试，平均产量5374．5kg／hm2，最高产量8250kg／hm2.蛋白质含量16．6％，容重790g，高抗黄矮病、锈病。

There are two kinds of valuable germplasm resources in our country,one is the Taigu genicmale sterility, the other is little quack grass(Tritelytrigia). Jinchum N0. 13 is the first spring wheatvariety selected through sub-distant cross breeding by using the It. posses rich genetic matrial, andso high-yield, good-quality, desease-resistane, as well as wider adaptability, and so on. Theoutput of Jinchum No. 13 occupied first place during be successive years province-level regional test.Furthermore, it has been cultivated in many areas and the output of it got to 5 250kg/ha that increased20%~22% more than Jinchun N0. 9(control). In nouthem regional test of 1997, 12 of 13 areasoccupied first place, the average yield was 5 374. 5kg/hm2, Jinchun N0. 13 contains 16. 6% protein,and it's natural weight is of 790g. It is also powerful resistant to wheat yellow dwarf virus and wheatrust.
