Embodiment Construction

[0020] The present invention is further described below:

[0021] The present invention provides embodiment:

[0022] A breeding method for green-grained sandy rice, using rouge rice, long-grain Hanxiang, black sticky incense, and black japonica as parents, pairing the parents participating in the hybridization in pairs to form single-cross hybrids, and then performing two single-crosses Hybrids are crossed, and the offspring are selected according to the pedigree method;

[0023] The breeding target of the green-grained sandy rice is: plant height 90-95 cm, average grain number per panicle 100 grains, thousand-grain weight 25 grams, tight panicle type, effective accumulated temperature of 2400°C, 132-135 days of growth days, organic fertility cultivation, Disease resistance, lodging resistance, cold damage resistance, medium tillering, high quality, green rice after husking, suitable for planting in the second and third accumulative temperate zones;

Abstract

The invention provides a breeding method of green-grain sand rice. The method comprises the following steps: by taking carmine rice, long-grain dry fragrant rice, black sticky fragrant rice and black japonica rice as parents, matching the parents participating in hybridization in pairs to form single-cross hybrids, then hybridizing the two single-cross hybrids, and breeding the progeny according to a pedigree method to obtain the green-grain sand rice. The dry rice produced by the method is stable in main agronomic character and short in growth period, meets the requirements of production and markets, has the same planting cost as that of conventional rice, and is higher in yield compared with other rice, resistant to disease, lodging and cold damage, moderate in tillering, excellent in quality, green when hulled, and suitable for planting in second and third accumulated temperature zones.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable breeding, and in particular relates to a breeding method of green-grain sandy rice. Background technique [0002] Agriculture is the foundation of the national economy. Improved crop varieties contribute more than 30% of the increase in agricultural productivity. The selection and promotion of crop varieties has achieved many important results and contributed to solving the problem of food and clothing for the Chinese population. The selection and promotion of improved varieties is an investment with little investment. , low energy consumption, and high-efficiency measures to increase production greatly improve agricultural productivity. [0003] Because the existing products have a long growth period, they cannot meet the needs of production and market. [0004] Therefore, it is very important to design a breeding method for green-grained sandy rice. Contents of the invention [...
