Abstract
The invention relates to a breeding method of a rice sterile line. A high-yield disease-resistant sterile line, namely Lu 18S, is taken as a female parent and high-quality and strong-genetic prematurity Guangzhan 63-4S is taken as a male parent for hybridization so as to breed the two-line sterile line which gathers excellent properties of the parents, and has high quality, high yield and strong genetic prematurity. By matching with a plurality of high-yield and high-quality restorer lines, hybrid varieties which are configured have the advantages of high yield, high quality and prematurity.
Description
Technical field:
The present invention relates to a kind of selection of rice sterile line.
Background technology:
A seed can change the world, and whether good kind is most important to the increases in grain production good harvest.The precocious rice varieties of breeding high-yield high-quality is many breeder's unremitting pursue.But on rice breeding, there are two principal contradictions to need to solve, the first, the contradiction of high yield and high-quality, often rice matter is poor for the high-yield rice kind, and the variety yield that rice matter is good is not high again.The second, high yield and precocious contradiction, the high-yield rice kind often the ripe phase slow, variety yield early of ripe phase is not high again.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and the selection of the rice sterile line of a kind of precocity, high yield, high-quality is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
The seed selection thinking:
A kind of selection of rice sterile line, take high-yield disease resisting male sterile line land 18S as maternal, take high-quality and have hereditary precocious power extensively to account for by force 63-4S as paternal hybrid, selects and assemble parents good characteristic, good quality and high output and the strong two-line sterile line of hereditary precocious power.
According to the selection of above-mentioned a kind of rice sterile line, First Year Hainan in February, take high-yield disease resisting male sterile line land 18S as maternal, take high-quality and have hereditary precocious power extensively to account for by force 63-4S as paternal hybrid, 40 of sowing;
First Year to the second year winter in year Hainan F1 adds and withholds kind of 3000 left and right;
The positive season F2 of Second Year separates plantation 2000 strains, selects 6 of of short stem, leaf inward-curl, the good individual plants of the leaf state of leaf color depth strain, cuts batch regeneration cold water and irrigates and receive an a small amount of seed;
3 years Hainan F3 of Second Year to the add generation, and the middle chalk that selects lacks 5 of individual plants in vain;
The 3rd year positive season plantation F4, eliminate susceptible individual plant, in conjunction with 3 of the low individual plants of breeding temperature in microscopy pollen, cuts batch regeneration cold water and irrigate;
Within the 3rd year to the 4th year, winter Hainan adds for F5, and roguing is short, 2 of leaf inward-curls, of fine quality, the resistance individual plant of rice, with 9311, hybridizes the survey advantages;
The 4th year positive season plantation F6, be 2 individual plants that seed is identified the fertility temperature, chooses the low two-line sterile line standard that reaches of one of them individual plant fertility temperature, and identify that by 9311 combos hybrid vigour is also stronger;
The 4th year to the 5th year Hainan plantation F7, the proterties stable and consistent, expand numerous core seeds.
The present invention by with a plurality of high yield and high quality restorer combos, the Hybrid configured all shows as high yield (kind of output and current establishing in large scale than volume increase more than 8%), high-quality (kind of the current establishing in large scale of meter Zhi Yu is than improving a class), precocious (kind of ripe phase and current establishing in large scale is than ripen in advance 5-7 days).
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
Seed selection thinking: take high-yield disease resisting male sterile line land 18S as maternal, take high-quality and have hereditary precocious power extensively to account for by force 63-4S as paternal hybrid, select and assemble parents' good characteristic---good quality and high output and the strong two-line sterile line of hereditary precocious power.Breeding Process is as follows:
In February, 2006, Hainan, take high-yield disease resisting male sterile line land 18S as maternal, take high-quality and have hereditary precocious power extensively to account for by force 63-4S as paternal hybrid, 40 of sowing; 2006-2007 winter Hainan F1 adds and withholds kind of 3000 left and right; Within 2007, positive season F2 separates plantation 2000 strains, selects 6 of of short stem, leaf inward-curl, the good individual plants of the leaf state of leaf color depth strain, cuts batch regeneration cold water and irrigates and receive an a small amount of seed; 2007-2008 Hainan F3 adds generation, and the middle chalk that selects lacks 5 of individual plants in vain; Positive season plantation F4 in 2008, eliminate susceptible individual plant, in conjunction with 3 of the low individual plants of breeding temperature in microscopy pollen, cuts batch regeneration cold water and irrigate; 2008-2009 winter Hainan adds for F5, and roguing is short, 2 of leaf inward-curls, of fine quality, the resistance individual plant of rice, with 9311, hybridizes the survey advantages.Positive season plantation F6 in 2009, be 2 individual plants that seed send Hua Zhong Agriculture University to identify the fertility temperature, wherein numbers the low two-line sterile line standard that reaches of S70-18 individual plant fertility temperature, and identify that by 9311 combos hybrid vigour is also stronger; 2009-2010 Hainan plantation F7, the proterties stable and consistent, expand numerous core seeds.2010-2012 participates in this department varietal yield test with different restorer test crosses in continuous 3 years, institute's combo close all show output high, rice of fine quality, the ripe phase short, output is high.To number the S70-18 male sterile line names: K18S.
Then, with a plurality of high yield and high quality restorers as WT26,9311 etc. with the K18S combo, the Hybrid configured all shows as high yield (kind of output and current establishing in large scale than volume increase more than 8%), high-quality (kind of the current establishing in large scale of meter Zhi Yu is than improving a class), precocious (kind of ripe phase and current establishing in large scale is than ripen in advance 5-7 days).
Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
