| 摘 要： | 通过对“克字号”小麦不同育种阶段代表品种产量与产量因素遗传改良的分析,研究“克字号”小麦的遗传改良进程,及其优质高产的原因。结果表明:在现代栽培技术条件下,目前推广的品种比地方品种增产近50%(47.1%),收获指数和千粒重分别增加了62.9%和32.5%。90年代以前产量的提高主要来源于穗粒重的增加,90年代后产量的提高则主要来源于千粒重和收获指数的提高。

| Abstract: | Through "Ke Zi Hao" Wheat varieties,the analysis of difference breedings which are stage representative of yield and factor hereditary improvement was done,research on "Ke Zi Hao" about wheat varieties in genetic improvement of wheat process and its high quality high yield reason was further analyzed.The results showed: Under modern culture technical condition,the kind which popularizes now increases higher production than local kind by near 50%(47.1%),gains index and mass of 1000 kernel have increased by 62.9% and 32.5% respectively.The raising of the former yield of 90s is major,source is in the grain heavy increase of ear of grain,after 90s the raising of yield is major,source is in mass of 1000 kernel the raising with gains index. |
