摘要: 应用普通小麦不同品种(品系)与苏玉4号杂交,喷洒100ppm的2,4—D一至二次,授粉后子房膨大,其膨大率因品种不同而异。在部分膨大子房中剥取到发育幼胚,经组织培养后,获得单倍体小麦植株,植株未结实。

Abstract: The various cultivars or lines of wheat (Triticum aestivum L. 2n=42) were used as the female parent in crosses with maize cultivar Suyn No. 4. (Zea mays L, 2n= 20) Wheat ovary swolled when sprayed with 100ppm 2,4-D post pollination. The rate of swollen ovary varied with the different rarieties. The infantile embryos obtained from the part of the swollen ovaries grew up to be a wheat haploid plants, by embryo culture. These plants are all sterile.
