摘  要:
Bo Ⅱ A, derived from the cross of Bo A∥Bo B/Ⅱ-32B, was improved from Bo A, a released CMS line with good grain quality. It was characteristic of stable male sterility, good flowering habit (anthesis time was mainly concentrated during 09:00~12:00), high stigma exsertion rate (82.18%), good pest resistance and good grain quality. The hybrids of it showed strong heterosis in grain yield. Among them, Boyou 968 (BoⅡA×08) was registered and released in Guangxi in 1999. The breeding procedure, major characteristics, performance of its hybrids and the main points of its multiplication and seed production techniques were introduced in this paper.
