Abstract:

The major male sterile genes in a new photo/thermo-sensitive genic male sterile (PTGMS) line B06S of rice were analyzed by the manipulation of mixture distribution theory. The results indicated that a pair of major male sterile nuclear genes with large effects were responsible for controlling the male sterility of B06S.

Key words: rice, photo/thermo-sensitive genic male sterile line, male sterile gene, inheritance, mixture distribution, Expectation and Maximization (EM) algorithm
