Researching method of dominant male genic male sterile material of hulless oat

Abstract

The invention relates to a researching method of a dominant male genic male sterile material of hulless oat. The researching method specifically comprises the following steps: (1), implementing a characteristic and feature researching method of the sterile material; (2), implementing the research on a hybridization method; (3), implementing a genetic analysis researching method of the sterile material, namely, 1, surveying the fertility of an F1-generation sterile material; 2, tracking and surveying a fertile line separated from the F1-generation sterile material; 3, surveying fertility conditions of the sterile material under different ecological conditions; (4), implementing a sterility surveying method of the sterile material; and (5), implementing application of a genic male sterile material on a hulless oat, namely, 1, hybridization; 2, seed selection; and 3, breeding. By adopting a breeding procedure of a genic male sterile single-cross single-gene progressive summating method, a genic male sterile double-cross double-gene progressive summating method and a dynamic gene pool hybridization breeding method, a research on a recurrent selection method is developed. According to the researching method, the breeding level and the selecting efficiency of the hulless oat are increased, the increase of producing varieties, the high speed of producing the varieties, and the good quality of produced varieties are facilitated, the social benefit is large, the hybridization efficiency is improved, the cost is lowered, and the economic benefit is good.

Description

technical field [0001] The invention relates to a research method for naked oat dominant male sterility material, which belongs to the field of biotechnology. Background technique [0002] Naked oats (A. nuda large grain naked oats) are the main food crops and feed in high latitude, high altitude, alpine and remote mountainous areas such as the three provinces of Hebei, Shanxi and Inner Mongolia in the north of North my country, the four provinces of Shaanxi, Gansu, Ningxia and Qinghai in the northwest, and the Liangshan and Liangshan mountains in southwest Yunnan, Guizhou, and Sichuan. The planting area of ​​forage crops in the alpine mountainous areas of Bashang and Baxia in Zhang and Cheng of our province accounts for 30-50% of the grain sowing area. In recent years, studies at home and abroad have confirmed that its seeds have the effect of lowering blood fat and blood sugar in the human body, and have been developed and utilized as a functional health food. Therefore, i...
