Salt-resistant Qixiang rice and breeding method thereof

Abstract

The invention discloses a salt-resistant Qixiang rice breeding method. The breeding method comprises the following steps that seed buds of scented rice species are subjected to homogenate processing,and slurry is obtained; the slurry is injected into rhizome nodes of marine plant spartina anglica, and rice seedlings are obtained; transplanting and fruit bearing are conducted, and primary aromaticrice seeds are obtained; the primary aromatic rice seeds are planted, rice seedlings of the primary aromatic rice seeds are obtained, and after fruit bearing, second generation aromatic rice seeds are obtained; the second generation aromatic rice seeds are planted in a seawater environment, and rice seedlings of the second generation aromatic rice seeds are obtained; spartina anglica homogenate culturing asexual embryo seedlings is continuously injected into rhizome nodes of the rice seedling of the second generation aromatic rice seeds, and after the third generation, salt-resistant Qixiangrice is obtained. The invention further provides the salt-resistant Qixiang rice. The method has the following advantages that the breeding cycle is shortened, the effect is good, the cost is low, thesalt-resistant capacity of the salt-resistant Qixiang rice obtained through breeding can reach 1% or above, the planting performance in the seawater environment is good, and the produced rice is goodin rice quality and rich in fragrance.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural breeding, in particular to a salt-resistant exotic fragrant rice and a breeding method thereof. 【Background technique】 [0002] The hybridization of rice and sorghum belongs to distant hybridization, and its success rate is low. Usually, rice is used as the female parent and sorghum is used as the male parent. It takes 20-40 years for such distant hybridization to form a variety. At present, the results in this area are relatively good. The sorghum rice Amethyst jointly bred by farmer breeders Tao Hongfa and Rao Shuijia has a greater impact, with good yield and rice quality. It is purple rice. The backcross method of rice-sorghum hybridization, that is, the breeding method with rice as the male parent and sorghum as the female parent, has not been reported in the academic circles. [0003] In the related technology, Huaihua Symbiosis Agricultural Systems Engineering Research Institute used...
