| 摘 要： | 本文在同步选育和相对一致的栽培条件下对辐射诱变在玉米群体改良进程中的影响作了初步的研究。结果表明,诱变使群体生育期缩短,但却引起光合面积减少。诱变对产量和单株生产能力以及果穗性状没有产生显著的或规律性的影响。辐射处理提高了群体的变异程度和范围。辐射群体某些性状的选择进展大于未辐射群体。

| Abstract: | Mass selection for lodging resistance and earlier (lowering and yield was conducted in Liaoju Synthetic of maize for three generations, Two sub-populations were subjected to ~(60)Cor-ray irradiation of seed at second generation. Irradiation resulted in decreasing in photosynthetic areas and earlier flowering. There was no evidence that irradiation had significant effects on traits related to grain yield as well as grain yield per seed Irradiation seemed to have effects on expanding coefficients and ranges of variations of some traits. In addition, the progress from selection for some traits was greater in irradiated populations than that in non-irradiated ones. |
