Embodiment 1

[0025] The invention provides a breeding method for black rice, which is characterized in that, selecting Wuyoudao No. 4, Salsa Ni and Rouge rice as parents, and performing additive hybridization, and then breeding by pedigree method after additive hybridization, code-named black rice, Include the following steps:

[0026] 1) Select Wuyoudao No. 4, Sashani and Yanzhidao as parents, and firstly cross the two parents of Wuyoudao No. 4 and Sashani, and then cross the resulting hybrid with Yanzhidao to obtain hybrid F1 , eliminate false hybrids and individual significantly bad plants, perform single plant selection, and obtain F2;

[0027] 2) Under the second accumulated temperature zone, sow in mid-April and transplant in mid-to-late May. The size of transplanting is 30 cm x 13.3-18 cm. Insert 2-4 plants in each hole. When planting, the number of plants should not be less than 3,000; After maturity, the individual plants of the F2 generation select the individual plants with exc...

Abstract

The invention provides a breeding method of black rice. The breeding method comprises the following steps: selecting Wuyou rice No.4, Shashani and carmine rice as parents, carrying out additive hybridization, and breeding by a pedigree method after additive hybridization. The code is black rice, the main agronomic traits are stable, a high quality fragrant type variety with good yielding ability, medium fertility cultivation in the growth period, and appropriate plant height is obtained; the rice is black and slender with a length-width ratio of 3: 1, and good in cooking property and palatability; and the variety is disease-resistant, lodging-resistant, cold-damage-resistant, moderately strong in tillering, excellent in quality and suitable for being planted in mid-late maturity rice cropping areas such as Siping, Jilin, Changchun, Liaoyuan and Songyuan in Jilin province.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable breeding, and in particular relates to a black rice breeding method. Background technique [0002] Upland rice is also called upland rice. Its biological characteristics, external shape and internal anatomical structure are similar to those of rice. For example, upland rice also has split aerenchyma suitable for swamp growth. Oxygen is insufficient under water conditions. Therefore, it can be considered that upland rice is a type of rice that is evolved from rice and is suitable for dry farming. Compared with rice, the biggest difference between upland rice and rice is that upland rice is suitable for dry field conditions. Planted under cultivation, it can grow well as long as the soil contains a certain amount of moisture. At present, upland rice is cultivated in many countries in the world, especially Brazil, which is famous for its large cultivation area and high yield. my country...
