Problems solved by technology

Although these combinations have taken into account the contradiction between high yield and high quality to a certain extent, due to the relatively single parentage of the main planting combinations of the two lines and the narrow genetic basis, the ecological adaptability is fragile. Poor resistance to natural disasters, weak ecological adaptability, and poor production stability

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Such as figure 1 and 2 Shown, a kind of method for mutagenic sterile line breeding high-quality light-temperature-sensitive two-line sterile line comprises the following steps:

[0025] 1) Mutation of the sterile line "Green 102S": the dry seeds of the sterile line "Green 102S" were used as the basic material, treated with cobalt-60γ-ray radiation, the treatment dose was 300Gy, the dose rate was 10Gy / min, and the treatment time was 30min. "Green 102S" M0 generation seeds were obtained after the transformation treatment;

[0026] 2) Breeding of a new type of high-quality light-temperature-sensitive two-line male sterile line "Xi 06S": the seeds of the "Green 102S" M0 generation that have been treated with radiation mutagenesis were used, a...

Abstract

The invention discloses a method for breeding a high-quality photothermo-sensitive two-line sterile line by mutagenizing a sterile line. The "Green 102S" (sterile line) was successfully induced and bred into a new high-quality photothermo-sensitive two-line sterile line. The breeding line "Xi 06S", compared with "Green 102S", the obtained "Xi 06S" has the characteristics of longer flowering period, stable sterile line, longer sterile period and strong combining ability, etc. It is suitable for indica medium indica Mountain male sterile line is planted in the suitable growing area. It has good reproductive ability, high quality, lodging resistance and other characteristics. The starting temperature of its fertility conversion is below 26 degrees.

Description

technical field [0001] The invention relates to a method for breeding high-quality light-temperature-sensitive two-line sterile lines by mutagenic sterile lines, and belongs to the field of agricultural technology. Background technique [0002] At present, most of the sterile lines of the two-line varieties in rice production are derived from the two main sterile lines of "Peiai 64S" and "Guangzhan 63S" and their derivatives, and most of the restorer lines are derived from "9311" and its derivatives . Although these combinations have taken into account the contradiction between high yield and high quality to a certain extent, due to the relatively single parentage of the main planting combinations of the two lines and the narrow genetic basis, the ecological adaptability is fragile. The ability to resist natural disasters is poor, the ecological adaptability is weak, and the stability of production is poor. Therefore, we propose a method for breeding high-quality photother...
