无融合生殖水稻8415品种是中国农科院作物所陈建三副研究员等经十多年时间,用种间杂交的方法选育出来的远缘杂种。该品种最大特点是母性遗传,F_2以后性状不发生分离,杂种优势能被固定下来。这种无融合生殖是母本的雌配子与父本的雄性配子没有融合的生殖,是一种非孟德尔遗传现象。它把具有无融合生殖特性的野生稻和籼稻。同栽培稻进行有性杂交,从后代中选育出具有无融合基因的杂种F_1,称作无融合生殖 Apomixis 8415 is a distant hybrid bred by interspecific hybridization after more than ten years of research by Chen Jian-san, a researcher of Chinese Academy of Agricultural Sciences. The most prominent feature of the breed is maternal inheritance, the trait does not segregate after F_2, and the heterosis can be fixed. This apomictic reproduction is a non-Mendelian genetic phenomenon in which female gametes of the female parent are not fused with male gametes of the male parent. It combines wild and indica rice with apomixis. Sexual crosses were made with cultivated rice, and the hybrid F1 with an apomixis gene was bred from the offspring, called apomixis
