| Abstract: | The genetic analysis of fertility restoration of “HL” type CMS was conducted by utilizing a CMS line Congguang 41A (A), a CMS maintainer Congguang 4lB (B), two CMS restorers Teqing and Zhenshan 97 (C) and their populations (A/C) F1, (A/C) F2, and (A∥B/C) BC1. The results indicated that fertility restoration of Teqing was controlled by a dominant gene, named Rf-5(t) tentatively; on the other hand, it appeared to be two kinds of genes in Congguang 41 and Zhanshan 97 to control fertility restoration of the “HL” type CMS. Allelism test of fertility restoration gene (s) of Teqing and Zhenshan 97 by a population Congguang 41A∥Teqing/Zhenshan 97 showed that there was a dominant gene allelic to Rf-5(t) in Zhenshan 97, and the other gene had not determined yet. |
