Abstract
The invention discloses a polymerization breeding method for rice. The polymerization breeding method for the rice comprises the following steps: selecting and determining a backbone variety of rice, taking four mutant varieties of the backbone variety of the rice as breeding materials, wherein different mutant varieties at least have one different excellent agronomic trait; grouping the four mutant varieties into two groups, mutually hybridizing the two mutant varieties in the first pair to obtain first double-cross F1<++> plants, and mutually hybridizing the two mutant varieties in the second pair to obtain second double-cross F1<++> plants; mutually hybridizing the first double-cross F1<++> plants and the second double-cross F1<++> plants to obtain four-way-cross F1<++++> plants; carrying out selfing on the four-way-cross F1<++++> plants, selecting four mutant varieties in four-way-cross F2<++++> plants and polymerizing to obtain a single polymerization plant with excellent agronomic trait; and systemically breeding the posterities of the single polymerization plant. The high-speed polymerization breeding method for the rice is simple, convenient and efficient, and is short in breeding period.
Description
Technical field
The invention belongs to breeding technical field, particularly relate to a kind of paddy rice pyramiding breeding method.
Background technology
For improving the general performance power of paddy disease-resistant, pest-resistant, quality and yield, carrying out multiple characters pyramiding breeding is important technological means.Concrete breeding method is diverse for the genetic background with different merit kind and the good kind of a Comprehensive Traits, respectively hybridization and back cross breeding.
Publication number is the selection that the Chinese patent literature of CN102754591A discloses a kind of multi-resistance rice germplasm, comprises the following steps: carry the parent P1 of Bacterial blight resistance gene Xa21 and Xa23 simultaneously and carry blast resistant gene Pi-K simultaneously
hwith the parent P2 phase mutual cross of Pi-1, obtain hybridization F1; Plantation F1, maturing stage sowing obtains F2 seed; Plantation F2, by going out the individual plant of the disease-resistant marker genetype of heterozygosis with the closely linked molecular marker screening of disease-resistant gene; The individual plant of plantation screening, results selfing F3 seed; Plantation selfing F3, selected the individual plant carrying the disease-resistant marker genetype that isozygotys by Molecular Marker Assisted Selection Technology, heading stage and recurrent parent P3 are hybridized; The hybridization F1 that plantation obtains, heading stage and recurrent parent P3 backcross, and obtain BC1F1 seed; Plantation BC1F1 seed, therefrom selects that strain Leaf pattern is close with recurrent parent P3 and individual plant that the is disease-resistant marker genetype of heterozygosis continues and recurrent parent P3 continuous backcross 3 generation, acquisition BC3F2 seed; Plantation BC3F2 seed, therefrom selects strain Leaf pattern and the individual plant selfing of heterozygosis disease-resistant marker genetype close with recurrent parent P3, acquisition BC3F3 strain, is tested and appraised, screens and obtain multi-resistant rice.
The parent P1 simultaneously carrying Bacterial blight resistance gene Xa21 and Xa23 and the parent P2 simultaneously carrying blast resistant gene Pi-Kh and Pi-1 are parent's raw material by above-mentioned patent, by convergent cross and Molecular Marker Assisted Selection Technology, Pi1, PiKh, Xa21 and the Xa23 be dispersed in different anti-source is imported in same rice germplasm, but breeding cycle is long, need the hybridization in many generations, backcross process.
Breeding cycle length is ubiquitous problem in current multiple characters paddy rice pyramiding breeding, due to the otherness of breeding material genetic background, proterties stable needs the hybridization grown to backcross the time very much, in addition, due to the greatest differences of breeding material genetic background, characters of progenies separate complex, the selection of breeding is difficult to control, and what cause breeding final goal is difficult to expection.When the merit be polymerized is more, the problems referred to above are also more outstanding, and often cause the failure of breeding.
With paddy rice key variety for object, the mutant of mutagenic and breeding series of different, has established good basis to parsing Main Agronomic Characters Forming Mechanism and breeding utilization.But the comprehensive utilization with different merit mutant is polymerized with proterties and not yet effectively carries out.
Summary of the invention
The present invention proposes a kind of paddy rice rapid polymerization breeding technique, and simple and effective, breeding cycle are short.
A kind of paddy rice pyramiding breeding method, comprising:
(1) select to determine paddy rice key variety, select four mutant lines deriving from this paddy rice key variety as breeding material, there is between different mutant lines the excellent economical character that at least one is different;
(2) it is two right to be divided into by described four mutant lines, and two mutant lines phases mutual cross of the first centering, obtains the first double cross F
1 ++for plant, two mutant lines phases mutual cross of the second centering, obtains the second double cross F
1 ++for plant;
(3) first double cross F
1 ++for plant and the second double cross F
1 ++for the mutual cross of plant phase, obtain four and hand over F
1 ++++for plant;
(4) four hand over F
1 ++++for plant selfing, obtain four and hand over F
2 ++++for plant, hand over F four
2 ++++the polymerization individual plant of selective polymerization four excellent economical characters of mutant lines in plant;
(5) systematic breeding is carried out to the offspring of described polymerization individual plant, obtain the rice varieties of multiple characters polymerization.
Described excellent economical character be tall and big strong stalk, disease-resistant, pest-resistant, tiller more, long grain, high-resistance starch or ripe late.
In step (5), the algebraically of described systematic breeding was 2 ~ 4 generations.By systematic breeding, carry out excellent in select excellent, can obtain the rice varieties of the multiple merit of stable polymerization (four kinds of mutant), generally, the algebraically of systematic breeding can shorten to for 2 generations.
As wherein a kind of selectable embodiment, described paddy rice key variety is " raising rice No. 6 ", and four described mutant lines are " the close rice in Zhejiang No. 1 ", " Zhejiang rice No. 1 ", " the anti-rice in Zhejiang No. 1 " and " Zhejiang many fringes rice ".Point pair time, preferably, described " the close rice in Zhejiang No. 1 " and " Zhejiang rice No. 1 " is a pair, and described " the anti-rice in Zhejiang No. 1 " and " Zhejiang many fringes rice " is a pair.
Alternatively, described paddy rice key variety is " Zhejiang extensive 7954 ", and four described mutant lines are " Zhejiang spoke 111 ", " the extensive 7954-LG2 in Zhejiang ", " the extensive 7954-BG3 in Zhejiang " and " LR7954 ".Point pair time, preferably, described " Zhejiang spoke 111 " and " the extensive 7954-LG2 in Zhejiang " is a pair, and described " the extensive 7954-BG3 in Zhejiang " and " LR7954 " is a pair.
Compared with prior art, beneficial effect of the present invention is:
(1) the present invention selects the mutant deriving from same paddy rice key variety as breeding material, due in rice breeding, the seed selection of rice mutant is carried out for specific economical character target, and other economical character and paddy rice key variety are similar to, so all mutant are except specific economical character is (as disease-resistant, pest-resistant, quality etc.) outward, remaining economical character is more consistent, that is the genetic background difference between all companion planting rice varieties is little, there is the uniformity of height, other proterties homogeneous of such breeding progeny is very easy to fast and stable and is convenient to select, compared with the huge kind pyramiding breeding of different genetic background difference, breeding selection facilitates feasible, breeding objective it is expected to.
(2) compared with the existing multiple characters pyramiding breeding that other is originated, breeding cycle of the present invention shorter (about general five generations), breeding process is more simple efficient.
