利用携有红米色素且抗寒基因的中间材料天红、掺粳恢复基因Ｒ４８１和广亲和基因“０２４２８”等不同类型材料为亲本复合杂交，经分步聚合逐层重组，多代跟踪测配，定向培育出具恢复力强（恢复度均在８０％以上）、亲和性好、抗寒性强的粳型红米恢复系——红零。经与不同胞质类型的籼型不育系测配鉴定，表现出较强的以穗粒优势为主的亚种间杂种优势。本文就恢复系的选育路线及对贵州有色稻米亚种间杂种优势利用的实用价值与应用前景作了探讨
Using different materials, such as Tianhong, Japonica restorer gene R481 and broad-compatibility gene “02428”, which are the intermediates of red rice pigment and cold-tolerant genes, were used as parents to compound hybridization. After stepwise polymerization, With the orientation, cultivate a restorer (recovery of more than 80%), good affinity, cold hardy japonica red rice restorer - red zero. The results showed that the interspecific heterosis, which is dominated by the grain-per-grain, was superior to that of indica-type CMS lines with different cytoplasm types. In this paper, the breeding line of restorer lines and Guizhou non-ferrous rice heterosis utilization of practical value and application prospects are discussed
