Embodiment

[0019] Such as figure 1 Shown, present embodiment provides a kind of production method of rice seed, comprises the steps:

[0020] S1: hybridization of A rice variety and B rice variety or multi-variety compound hybridization or biological, physical, chemical and other methods to produce trait hybrids, and collect F1 generation rice hybrid seeds;

[0021] S2: Sowing and cultivating F1 generation rice hybrid seeds, and collecting F2 generation rice seeds;

[0022] S3: Sowing and cultivating the F2 generation rice seeds, and collecting the F3 generation rice seeds;

[0023] S4: Sow and cultivate the F3 generation rice seeds, plant the cultivated rice piles under the isolation conditions of Hainan Island for annual planting, divide the plants continuously until the regenerated seedlings reach the required number of seedlings, then self-cross, and collect the F4 generation rice seeds;

[0024] S5-1: Sow and cultivate the F4 generation rice seeds, then carry out population stabi...

Abstract

The invention relates to a paddy rice seed production method and an application thereof. The production method comprises the following steps: S1: rice variety A and rice variety B are subjected to hybridization or multi-variety composite hybridization, or biological, physical, and chemical methods to generate a property heterozygote, and F1-generation paddy rice hybrid seeds are collected; S2: theF1-generation paddy rice hybrid seeds are sown and cultured, and the F2-generation paddy rice seeds are collected; S3: the F2-generation paddy rice seeds are sown and cultured, and the F3-generationpaddy rice seeds are collected; S4: the F3-generation paddy rice seeds are sown and cultured, and then are subjected to self-hybridization, and the F4-generation paddy rice seeds are collected; and S5-1: the F4-generation paddy rice seeds are sown and cultured, colony stability identification is carried out, the F3-generation rice stubble corresponding to the stable and standard F4-generation colony is subjected to regeneration breeding; a material after regeneration breeding is continuously cultivated, and after self-hybridization, the seeds are collected to obtain the required seeds.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for producing rice seeds and an application thereof. Background technique [0002] Rice is an annual grass plant, about 1.2 meters high, with long and flat leaves, and panicles composed of many spikelets. The fruit is rice, which is called rice or rice after shelling. Rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Paddy rice is called rice or rice after shelling the rice grains. In addition to being edible, rice can also be used as a raw material for brewing wine and sugar industry. Rice husk and rice straw also have many uses. Rice belongs to the Poaceae Oryza genus and is an extremely ancient crop. According to archaeological findings, rice has been planted in my country for at least 7,000 years. The cultivated rice in the world includes Asian cultivated rice and African cul...
