Abstract

A male sterile germplasm of Chinese jujube (Ziziphus jujuba Mill.), named ‘male sterile No.1’ (JMS1), was firstly identified from a natural population through studies of pollen amount and vitality and its anatomy. Its microspores got massed and then disaggregated after the tetrad stage during pollen development. Then its anthers became empty, or only pollen vestiges remained in the yellow buds. The pollen became abortive after the tetrad stage. Hypertrophy and hyperplasia of tapetum at the tetrad stage were related to pollen abortion. In view of its moderate embryo fertility, big fruit-size and early maturing, ‘JMS1’ could be used as a worthwhile female parent in the cross breeding of Chinese jujube.

Key words： Chinese jujube; male sterility; new germplasm; male sterile No.1
