A kind of breeding method of rice variety with pink leaves

Abstract

The invention discloses a breeding method for a rice variety having pink leaves. The breeding method comprises: selecting rice having pink leaves as a parent strain A, selecting rice having golden yellow hull as a parent strain B, selecting a rice having black seed coat as a parent strain C, and respectively carrying out hybridization on the parent strain A and the parent strain and on the parent strain A and the parent strain C to obtain two single cross F1 generation seeds; carrying out hybridization on the two single cross F1 generation seeds to obtain a double cross F1 generation seed; planting the double cross F1 generation seed, and constructing a doubled haploid population by using anther culture; planting a DH1 generation, and selecting a strain having pink leaves, golden yellow hull and black seed coat; planting DH2-DH4 generations, and selecting an excellent strain, wherein the excellent strain is the partial japonica type, the yield per mu of the excellent strain is more than 350 kg, and the growth period of the excellent strain is 130-140 days; and planting a DH 5 generation, and breeding a shaped rice so as to obtain the horticultural rice, wherein the shaped rice has pink leaves, golden yellow hull and black seed coat, the yield per mu of the shaped rice is more than 350 kg, and the growth period of the shaped rice is 130-140 days. According to the present invention, with the breeding method, the new rice variety organically integrating the ornament and the use can be developed, such that the added value of the rice can be increased, and the new rice variety can be linked to the tourism industry.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a method for breeding rice varieties with pink leaves. Background technique [0002] With the innovation and development of agricultural technology and the rapid expansion of agricultural functions, the concept of creative agriculture has been formed in foreign countries, especially in developed countries, and has rapidly expanded globally. There are mainly: (1) Farmland art, which is to create artistic patterns on farmland, the most representative Prominent ones include British crop circles, Japanese rice field art, and American corn mazes; (2) flower field landscapes, which use flowers to create magnificent flower field landscapes, the most representative ones are the spring flower seas in the Netherlands and the lavender flower seas in France . [0003] In recent years, the combination of agricultural production and agricultural tourism in my country has become an organ...
