Embodiment 1

[0045] Example 1 Screening of High Combining Ability Hybrid Parent Resources

[0046] The flow chart of the fragrant glutinous purple rice variety that the present invention carries out plant purple with conventional breeding is as figure 1 As shown, the mark "can be the parents of each other" in the place of "purple purple glutinous rice variety I × fragrant glutinous rice variety II" means that the purple glutinous rice variety I with purple plants can be used as the female parent, and the fragrant glutinous rice variety II can be used as the female parent. The male parent can also be crossed with the fragrant glutinous rice variety II as the female parent and the purple glutinous rice variety I with purple plants as the male parent.

[0047] If the plant purple fragrant glutinous purple rice variety breeding of the present invention is carried out in combination with biotechnology, then it is: Utilize conventional biotechnological means to introduce the gene of controlling ...

Embodiment 2

[0052] Embodiment 2 hybrid combination preparation and new strain pedigree selection

[0053] In April 2007, in the network room of Wenshan Academy of Agricultural Sciences, according to the sowing date of Wenzi 6 and Wendao 4, Wenzi 6 and Wendao 4 were sowed respectively. By July 2007, we used Wenzi No. 6 as the female parent and Wendao No. 4 as the male parent (you can also use Wendao No. 4 as the female parent and Wenzi No. 6 as the male parent). In Wenzi No. 6, the purple and purple rice genes of the controlled plants are introduced into Wendao No. 4, and the plant purple and purple rice trait genes of Wenzi No. 6 and the aroma trait genes of Wendao No. 4 are integrated, such as the excellent genes in the present invention Polymer Hybrid Generation III. Specifically, the female Wenzi No. 6 was artificially clipped and emasculated to prevent self-pollination, and the pollen of Wendao No. 4 was artificially pollinated on the stigma of Wenzi No. 6 for artificial pollination ...

Embodiment 3

[0055] Embodiment 3 Strain comparison selection and multi-point product comparison test

[0056] The selected 24 strains not only have plant purple, purple rice and fragrance, but also other economic traits such as growth period, plant type, leaf type, tillering ability, plant height, ear type, grain type, number of grains per ear, and seed setting rate. , especially yield is often inconsistent, therefore, need to use fine variety, parent as control, carry out strain comparison experiment, select excellent strain therefrom, especially select the strain that yield is higher than contrast, parent, just can have popularization value. In April 2010, 24 strains were planted at the Wenshan Base of the Wenshan Academy of Agricultural Sciences. Taking Wenzi No. 6, Wendao No. 4 and Wennuo No. 1 as controls, 480 single seedlings were planted in each plot, with 12 strains per row. A total of 40 rows were planted. For each plot, 10 plants in the middle of the second row from the side row...

Abstract

The invention discloses a method for breeding a purple-plant purple fragrant glutinous rice variety. The method specifically comprises the following steps: collecting a purple-plant purple glutinous rice variety and a fragrant type glutinous rice variety respectively, performing combining ability determination, and selecting a purple-plant purple glutinous rice variety I with strong combining ability and a fragrant type glutinous rice variety II with strong combining ability respectively; introducing genes for controlling purple rice and purple plants in the purple-plant purple glutinous rice variety I into the fragrant type glutinous rice variety II to obtain a hybrid first generation III with a target gene for polymerization control of purple rice, purple plants, fragrance and glutinous rice; performing continuous selfing breeding to obtain a stable purple-plant purple fragrant glutinous rice strain IV; and performing variety comparison test and multipoint test to obtain a purple-plant purple fragrant glutinous rice variety V. The purple-plant purple fragrant glutinous rice variety V bred by the method disclosed by the invention is high in yield and also is rich in plant and rice fragrance, and the rice has purple husks, is glutinous, and has effects of being used as a medicine and a food; and in the seedling stage of the rice plants, the whole rice plants are purple except roots, and after grain grouting, the color gradually turns into green.

Description

technical field [0001] The invention relates to rice breeding technology, in particular to a method for breeding fragrant glutinous purple rice varieties with purple plants. Background technique [0002] Purple black rice, also known as purple rice or black rice, is called purple rice in the present invention, which means that anthocyanin pigments accumulate in rice peels and seed coats in large quantities, so that brown rice appears purple red, purple black, jet black and other colors. It is named after black and purple, and it is a kind of precious rice with both medicine and food and many health benefits. Therefore, it is also called medicinal rice, blood-enriching rice, moon rice, longevity rice, tribute rice and pearl rice. There are two types of rice quality: waxy and sticky, but most of them are waxy. [0003] Traditional Chinese medicine believes that purple glutinous rice can nourish the kidneys, improve the functions of the heart, liver, spleen, and stomach, stren...
