Method for breeding horticulture type clustered floret rice material

Abstract

The invention discloses a method for breeding a horticulture type clustered floret rice material. The method comprises the following steps: selecting donor parents; introducing total DNA of barnyard grass into a formed rice material; planting an introduced DNA progeny material and performing single plant harvesting to obtain D1 seed rice; planting 5-10 rows of single plants of the D1 in a single plant row area and respectively performing mixed harvesting on the single plants to obtain D2 seed rice; planting 10-15 rows of single plants of the D2 and performing single plant harvesting on variant plants of the floret cluster characteristic and character partial donor barnyard grass to obtain seed rice D3; planting floret clustered single plants of the D3, screening and obtaining single plants with excellent performance to obtain D4 seed rice; selecting a floret clustered D4 generation with a good comprehensive property to perform adding-generation reproduction and obtaining the clustered floret rice material; selecting the floret clustered D4 generation with the good comprehensive property to hybridize with a formed parent material, creating a new clustered floret rice material. The method disclosed by the invention effectively solves the problem of shortage of the horticulture type rice material.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a method for selecting and breeding horticultural-type clustered floret rice materials. Background technique [0002] For a long time, food security and supply guarantee have been the main functions of rice. With the development of society and the improvement of people's living standards, the functions of rice have gradually been given more food, health care, and appreciation from the single food security and supply guarantee. Many functions. Health-care and horticultural rice such as red rice and black rice, purple leaf and flower leaf have been more and more recognized by people. [0003] Therefore, it is of great practical significance to provide a breeding method for horticultural rice materials for the development of new functions of rice under new forms and to solve the shortage of horticultural rice materials.
