Embodiment 1

[0024] The technical solution of the present invention is a method for cultivating a new variety of fragrant rice, comprising the following steps:

[0025] S1: Select fragrant rice as the female parent, select non-aromatic high-yield rice in the existing varieties as the male parent, and cross the female parent with the male parent to obtain a hybrid F1;

[0026] S2: Plant the F1 generation, select a single plant with a seed setting rate of ≥70%, a plant height of 97cm, and a grain length of more than 6mm for fragrance detection, and the lines with fragrance are tested for appearance quality, and the chalk rate is less than 35%. Transparent strains are used as F2 generation;

[0027] S3: Cross the F2 generation with the female parent of S1 medium-aromatic rice, select a single plant with a seed setting rate of ≥80%, a plant height of 102 cm, and a grain length of more than 7 mm for aroma detection, and obtain the F3 generation. Quality inspection, select the line with chalk r...

Embodiment 2

[0039] The technical solution of the present invention is a method for cultivating a new variety of fragrant rice, comprising the following steps:

[0040] S1: Select fragrant rice as the female parent, select non-aromatic high-yield rice in the existing varieties as the male parent, and cross the female parent with the male parent to obtain a hybrid F1;

[0041] S2: Plant F1 generation, select a single plant with a seed setting rate of ≥70%, a plant height of 95cm, and a grain length of more than 6mm for fragrance testing, and the fragrance-bearing lines for appearance quality testing, select chalk rate less than 35%, grains Transparent strains are used as F2 generation;

[0042] S3: Cross the F2 generation with the S1 medium-aromatic rice female parent, and select a single plant with a seed setting rate of ≥80%, a plant height of 100 cm, and a grain length of more than 7 mm for fragrance detection, and obtain the F3 generation. Quality inspection, select the line with chalk...

Embodiment 3

[0054] The technical scheme of the present invention is a method for cultivating a new variety of fragrant rice, comprising the following steps:

[0055] S1: Select fragrant rice as the female parent, select non-aromatic high-yield rice in the existing varieties as the male parent, and cross the female parent with the male parent to obtain a hybrid F1;

[0056] S2: Plant F1 generation, select a single plant with a seed setting rate of ≥70%, a plant height of 100cm, and a grain length of more than 6mm for fragrance testing, and the fragrance-bearing lines for appearance quality testing, select chalk rate less than 35%, grains Transparent strains are used as F2 generation;

[0057] S3: Cross the F2 generation with the S1 medium-aromatic rice female parent, select a single plant with a seed setting rate of ≥80%, a plant height of 105cm, and a grain length of more than 7mm for aroma detection, and obtain the F3 generation. Quality inspection, select the line with chalk rate less ...

Abstract

The invention discloses a method for cultivating a new variety of aromatic rice, which comprises the following steps: selecting aromatic rice as a female parent, selecting non-aromatic high-yield rice in the existing variety as a male parent, and hybridizing the female parent and the male parent to obtain a hybrid F1; after four generations of breeding, shaping rice of a plant line with the yield higher than 400 Kg / mu, the thousand seed weight larger than 30 g, transparency and the grain length larger than 7 mm is obtained. According to the method disclosed by the invention, the aromatic female parent and the non-aromatic parent are hybridized as parents, and then the hybrid offspring is bred, so that the cultivated rice has high yield while having aromatic flavor. In the cultivation process, factors such as fragrance, yield, thousand seed weight, transparency, grain length and the like are used as screening standards, and the stable fragrant rice variety is finally obtained through four generations of breeding.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, and more particularly, to a method for cultivating new varieties of fragrant rice. Background technique [0002] Rice is one of the most important food crops in the world, providing approximately 25% of the energy for more than 3 billion people worldwide. For the residents of Southeast Asia, rice provides more than 35% of their energy. About 65% of people in China eat rice as their staple food. With the continuous improvement of rice production and the continuous improvement of people's living standards, people have put forward higher requirements for the eating quality of rice. As one of the types of rice cultivated, fragrant rice not only has a fragrant aroma and fragrant rice, but also has high nutritional value. According to the "Compendium of Materia Medica", fragrant rice can "moisten the heart and lungs, harmonize all medicines, and prolong life" when taken for a long time. Kno...
