Breeding of Male Sterile Lines by Hybridizing Millet Varieties
摘要
Abstract
The hybrid combinations of millets were bred by Anyang Academy of Agricultural Sciences from 2001 to 2008 and some sterile lines were produced in their sterile offspring. The pollination trait of these lines and fertility recoverability of F1 hybrids were determined. The results showed that sterile plants were 21.7％ probability in the progenies,and the sterile combinations of good heritance accounted for 25.8％ of the total sterile combinations. Pollination tests showed that all of the sterile lines could be fertilized by foreign pollen and seed, which were applicable in the preparation of conventional breeding combinations. The fertility recoverability tests of F1 hybrids showed that they all recovered fertility, but with different degree of recovery. The hybrids with a higher degree of recovery could be applied to millet hybrid breeding. Selection of male sterile lines by hybridizing millet varieties for conventional breeding crosses was a feasible means to solve the problem of difficult artificial hybridization of millet, and to accumulate male sterile materials for millet hybridizing breeding.关键词
