Abstract
A kind of rice merges the method that rice seed is educated in distant hybridization with pseudo-ginseng root system, and method is：The root system of rice and pseudo-ginseng root system cell fusion and hybridization are educated into rice seed.Producing method for seed is：A. root system merges:Rice plant is planted in paddy field, by notoginseng planting at nonirrigated farmland, the line-spacing of rice and pseudo-ginseng is 30 50 centimeters, and the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, and root cell combines together when interlaced；B. choose seeds:By the rice paddy seed of rice plant color purpling, alternatively object is chosen seeds, and it is that rice merges hybrid rice kind with pseudo-ginseng root system that the rice plant color, which becomes empurpled rice paddy seed,.Advantage:The root system for the rice that this method is brought out merges the rice paddy seed of hybridization with pseudo-ginseng root system, and its characters of progenies is stable, does not separate, and its rice plant well developed root system and tillering ability are strong, and existing the sixth of the twelve Earthly Branches plants experimentally 2 years per mu yields up to 900 1000 kilograms.
Description
Technical field
Present invention relates to rice breeding method field.
Background technology
Existing rice breeding method is generally pollen and is cross-breeding for male parent, but distant hybridization is that pollen is male parent
Carry out hybridizing extremely difficult success.
The content of the invention
Existing rice breeding method is generally pollen and is cross-breeding for male parent, but distant hybridization is that pollen is male parent
The deficiency for hybridizing extremely difficult success is carried out, and kind of a rice is provided the method that rice seed is educated in distant hybridization is merged with pseudo-ginseng root system.
The present invention method be：
The root system of rice is merged into hybridization with pseudo-ginseng root system and educates rice seed.
Breeding method is：
A. root system merges:Rice plant is planted in paddy field, by notoginseng planting at nonirrigated farmland, the row of rice and pseudo-ginseng
Away from for 30-50 centimetres, the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, and root cell melts when interlaced
It is integrated；
B. choose seeds:Rice plant color is become into blue rice paddy seed, and alternatively object is chosen seeds, the rice plant
It is that rice merges hybrid rice kind with pseudo-ginseng root system that color, which becomes empurpled rice paddy seed,.
Specific method is：
To be maternal and rice breeding with rice breeding " 691 " --- " Anhui rice 64 " is to hybridize made of paternal hybrid
Seed, after planting for four to five generations, the unseparated seed of selection traits good stable is planted in paddy field, by notoginseng planting in drought
It is located in, the line-spacing of rice and pseudo-ginseng is 40 centimeters, and the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, mutually
Combined together when staggeredly.
Advantage:The root system for the rice that this method is brought out merges the rice paddy seed of hybridization, its characters of progenies with pseudo-ginseng root system
It is stable, do not separate, its rice plant well developed root system and tillering ability are strong (every can tiller 38-40 roots), and existing the sixth of the twelve Earthly Branches plants experimentally 2 years
Per mu yield is up to 900-1000 kilograms.
Embodiment
Play a plurality of equidistant ridge in paddy field, ridge top will expose the surface in nonirrigated farmland shape, and discharge water rice cultivation plant in ditch, ridge
Upper plantation pseudo-ginseng, rice is (so that rice breeding " 691 " is by female parent and rice breeding --- " Anhui rice 64 " is made up of paternal hybrid
Hybrid seed) and pseudo-ginseng line-spacing be 40 centimeters, the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, phase
Root cell combines together when mutually staggeredly；By the rice paddy seed of rice plant color purpling, alternatively object is chosen seeds,
It is rice and pseudo-ginseng root system cell fusion and hybridization rice seed that the rice plant color, which becomes empurpled rice paddy seed,.
Boiled water rice varieties, are shown in during " 691 " are slow《Hubei agricultural science》04 phase in 1973." the Anhui Province of Anhui rice 64 "
Academy of agricultural sciences's rice from 2277 × the third 814 offspring in through systematic breeding in the late round-grained rice kind being bred as in 1997.Sedum uizoon,
Claim：Gynura segetum, Gynura Root, XUESANQI, chrysanthemum leaf pseudo-ginseng, water pseudo-ginseng.Belong to Angiospermae, Rosales, Crassulaceae, Sedum.
Claims (2)
1. a kind of rice merges the method that rice seed is educated in distant hybridization with pseudo-ginseng root system, it is characterised in that method is：
A root systems merge:Rice plant is planted in paddy field, by notoginseng planting at nonirrigated farmland, the line-spacing of rice and pseudo-ginseng is 30-
50 centimeters, the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, and root cell permeates when interlaced
Body；
B chooses seeds:By the rice paddy seed of rice plant color purpling, alternatively object is chosen seeds, and the rice plant color becomes
Empurpled rice paddy seed is that rice merges hybrid rice kind with pseudo-ginseng root system.
2. the rice described in a Ju claim 1 merges the method that rice seed is educated in distant hybridization with pseudo-ginseng root system, it is characterised in that
Method is：
To be maternal and rice breeding with rice breeding " 691 " --- " Anhui rice 64 " is hybrid seed made of paternal hybrid,
After planting for four to five generations, the unseparated progeny seed of selection traits good stable is planted in paddy field, by notoginseng planting in drought
It is located in, the line-spacing of rice and pseudo-ginseng is 40 centimeters, and the root system of rice plant and the root system of pseudo-ginseng plant are in growth course, mutually
Combined together when staggeredly.
