Embodiment

[0023] In the season of 2003, Wuyunjing 21, an early-maturing, high-yielding, mid-maturing mid-maturing japonica rice variety resistant to rice stripe leaf blight, was selected as the female parent in Jurong (Wuyunjing 21 is a rice variety produced by Jiangsu Wujin Rice Research Institute and is currently on the market. It is sold in large quantities on the Internet, or quoted from the rice germplasm resource bank of Jiangsu Academy of Agricultural Sciences), Wuxiangnuo 2402, a mid-maturing late japonica glutinous line with resistance to rice blast, high yield, and good ripeness (a mid-maturing late japonica glutinous line, available on the market Available for sale, or quoted from the Rice Germplasm Resource Bank of the Jiangsu Academy of Agricultural Sciences) to obtain 60 seeds from hybridization, that is, F 0 , 16 plants were planted in Hainan in the spring of 2004, and the individual plants with the same growth as the female parent were removed to obtain F1; after 6 genera...

Abstract

The invention discloses a method for breeding non-glutinous rice and / or glutinous rice varieties through non-glutinous rice and glutinous rice hybridization. According to the invention, Wuyunjing No.21 is selected as a female parent, and is hybridized with Wuxiangnuo 2402; and breeding is carried out, such that a required variety is obtained. Through six generations of selection and resistance identification, the bred variety has the advantages of compact plant type, delicate and pretty growth state, good yield, good lodging resistance, and good quality.

Description

technical field [0001] The invention relates to a plant breeding method, more specifically to a method for efficiently breeding japonica rice and / or glutinous rice varieties through japonica-waxy crossing. Background technique [0002] Rice is the largest crop in my country. There are mainly two subspecies of rice cultivated in China, namely the indica subspecies and the japonica subspecies. The japonica and glutinous rice varieties are indispensable for our daily life and industrial production. In recent years, with the improvement of people's living standards, the adjustment of planting structure and the pressure of international market competition, the improvement of rice resistance and quality has become more and more important. Most of the glutinous rice varieties currently planted in Jiangsu have low yields, are susceptible to rice stripe leaf blight, and have degraded resistance to rice blast. The comprehensive resistance and quality of japonica rice varieties are not...
