Abstract: This paper summarized that through the regulation of spectrum, light intensity, light duration, temperature, humidity and carbon dioxide concentration,the intelligent breeding plant of polyploid rice in the whole growth period had realized the rapid propagation of 3~4 generations a year;Secondly, in the establishment of polyploid rice germplasm and hybrid breeding, seasonal restrictions could be put aside for rice ploidy morphological identification and hybrid embryo rescue seedling propagation; In addition, while using anther culture for haploid rapid generation and stability, combined with gene chip gene detection and other high-tech breeding auxiliary means, it could eliminate the single plant with bad characters in the intelligent breeding factory, retain the single plant with good characters, transplant it to the field for propagation and identification, and finally select a new line to achieve the breeding goal.

Key words: polyploid rice, intelligent breeding plant, increasing generation and rapid propagation, assisted breeding
