Embodiment 1

[0027] 1. Breeding materials:

[0028] 1) Longke 638S was used as the female parent. Longke 638S is a two-line male sterile line bred by Hunan Yahua Seed Industry Science Research Institute. This variety has been applied for and authorized by the Plant Variety Protection Office of the Ministry of Agriculture. The variety right number: CNA20090950.7 can be purchased from Hunan Yahua Seed Industry Science Research Institute. This variety is a two-line sterile line that has been widely used in my country in recent years. The hybrid rice prepared has the advantages of high yield, high quality and wide adaptability.

[0029] 2) Kangyangdao No. 6 (Yangdao No. 6 × Gumei No. 4, BC 3 f 5 ) as the male parent. Among them, Yangdao No. 6 was bred by the Agricultural Science Research Institute of Lixiahe District, Jiangsu Province. This variety has been applied for and authorized by the Plant New Variety Protection Office of the Ministry of Agriculture. The variety right number: CAN20...

Abstract

The invention relates to a breeding method for a rice-blast-resistant good-quality high-yield two-line hybrid hsien rice combination, and belongs to the technical field of the crop genetic breeding. The method is capable of, through a molecular marker-assisted selection technology (MAS), combining principal agronomic character selection, importing a broad-spectrum and lasting rice-blast-resistantgene Pigm to a two-line sterile line, breeding a new rice-blast-resistant two-line sterile line, and using the bred rice-blast-resistant two-line sterile line to be matched with a good-quality restoring line with strong heterosis, breeding the rice-blast-resistant good-quality high-yield two-line hybrid hsien rice combination, thereby improving rice blast resistance of the first generation of hybrid, and enabling the combination to meet current requirements of rice production.

Description

technical field [0001] The invention provides a method for selecting a high-quality and high-yield two-line hybrid indica rice combination resistant to rice blast, and belongs to the technical field of crop genetics and breeding. Background technique [0002] Rice is one of the main food crops in my country and even in the world. High yield, high quality and disease resistance are important breeding goals of rice. As an effective way to improve rice yield and quality, two-line hybrid rice has been widely used and promoted, and has made a great contribution to food safety production. Applications. Therefore, there is an urgent need to improve the blast resistance of two-line hybrid rice to meet the needs of rice production. Rice blast caused by Magnaporthe oryzae is one of the most important fungal diseases threatening the safety of rice production in the world. Rice blast caused by rice blast reduces rice production by 10%-30% every year in the world. In the past 40 years...
