Breeding method of five-color rice carmine rice

Abstract

The invention provides a breeding method of five-color rice carmine rice. The breeding method comprises the following steps: carrying out sexual hybridization by taking a Xiangjing variety, namely Suijing No.4, as a male parent and a japonica rice variety, namely Heijing No.10, as a female parent, breeding by a pedigree method after hybridization, and carrying out pedigree method selection and character identification technologies to realize polymerization of excellent characters so as to obtain a high quality fragrant type new variety with a code carmine rice which is good yielding ability, cultivated with medium fertility in a growth period, and proper in plant height. The rice is elliptical, large in length-width ratio, good in cooking characteristic and palatability, high in gel consistency, high in amylose content, disease resistant, lodging resistant, cold damage resistant, moderately strong in tillering and excellent in quality, and the variety is 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 for multicolored rice carmine. Background technique [0002] About 60% of the population in my country takes rice as the staple food, so increasing rice production is a major issue for the sustainable development of agriculture and ensuring food security in my country. As the process of industrialization and urbanization is engulfing rice fields, it is necessary to meet the challenges of population growth for food demand.
