Abstract:

The main factors affecting the development of apomictic embryogenesis in plants are summarized from five perspectives: genetic control, environmental impact, ploidy implications, hormone levels and mineral regulation, and the timing and location of the aposporous initiation cell. The purpose of this review is to develop a systematic understanding of the mechanism of apomixis in plants. In particular, research on apomixis in Poa pratensis is reviewed, factors limiting its occurrence are identified, theoretical advantages of its application are evaluated, and prospects for the use of apomixis in P. pratensis breeding and new germplasm creation are explored. This study provides a theoretical basis for the breeding and development of new varieties of P. pratensis.

Key words: apomixis, genetic control, polyploidy, aposporous initiation cell, Poa pratensis
