近年来,国内一些单位采用孤雌生殖育种技术已经培育出油菜、小麦及水稻等作物新品种,并在生产上示范推广。但因化学诱导孤雌生殖未经典型的精卵结合,早期单性膨大的子房往往中途停止发育,最终结实种子甚少。1982年以来,我们以“四优30”等7个釉型杂交水稻F_1为材料,研究化学诱导水稻孤雌生殖子房的离体培养。目前已获得“四优30”、 In recent years, some domestic units have adopted parthenogenetic breeding techniques to breed new crop varieties such as rapeseed, wheat and rice and have demonstrated and promoted their production. However, due to chemical-induced parthenogenetic non-classical sperm-egg combination, the early ovarian sessile ovary often stop development, the final seed is very small. Since 1982, we studied the chemical-induced in vitro culture of parthenogenetic ovary in seven glaze hybrid rice F_1, such as “Siyou 30”. Has been “Siyou 30”,
