报道了296B做为一种新的无融合生殖材料在固定杂种优势中的作用,并对其杂交不孕性的遗传规律进行了研究,发现296B作母本的不亲和性与R473相似,其杂交不孕性由细胞质控制。296B与R473具极高的亲和力,二者杂交产生的类杂种后代不同于双亲,可能为一种接近专性的无融合生殖新类型。
Reported 296B as a new apomictic material in the role of fixed heterosis, and its genetic rules of hybrid infertility were studied and found that 296B as a mother of incompatibility with R473 similar Infertility is controlled by the cytoplasm. 296B and R473 have very high affinity. The hybrid progeny produced by the two hybrids are different from their parents and may be a new type of apomixis.
