Abstract
The present invention relates to a rice planting method which can be monitored. Said method includes the following steps: (1) selecting and using hybrid rice sterile line carrying yellow leaf label in whole growth period duration, making propagation breeding and preparing hybrid; (2) in the production of making propagation breeding and preparing hybrid making auxiliary impurity removal, if seedling or plant carries yellow leaf label it is true sterile line, if it is normal green or other color, it is false sterile line, must be completely removed; (3) in the field planting removing impurity and retaining purification, observing growth condition of hybrid generation, removing false sterile line.
Description
Technical field
The present invention relates to a kind of paddy rice planting method of monitoring.
Background technology
Seed purity is the basis of higher yield of crops and produces the deciding factor of promoting.For ensureing seed purity, the rice sterile line seed that plantation is used mainly contains morphology character test method, isoenzymes and protein electrophorese survey method, three kinds of molecular markers for identification methods at present.Ability from practical standpoint and solution practical problem although above-mentioned three kinds of methods have spent great amount of manpower and material resources and financial resources, all can only obtain the master data of hybrid rice hybrid purity, does not have the function of effective eliminating pseudostationary.
Summary of the invention
The object of the present invention is to provide a kind of paddy rice planting method of monitoring, each production process of effective monitoring paddy rice.
The paddy rice planting method of monitoring of the present invention is characterized in that may further comprise the steps:
1) selects the sterile line of hybridized rice that carries yellow leaf marker the time of infertility for use, carry out numerous kind and hybridization;
2) auxiliary impurity elimination during numerous, the production of hybrid seeds is produced then is genuine male sterile line if seedling or plant are carried yellow leaf marker, if normal green or other color then is the false male sterile line that mixes wherein, manually pulls out immediately;
3) the impurity elimination guarantor is pure in the field planting, observes the growing state of the first generation of hybrid, carries yellow leaf marker if find seedling or plant, manually pulls out immediately.
The above-described yellow leaf marker that carries, seedling to ripe whole growth process at rice sterile line is expressed as yellow, yellow, faint yellow or yellow green, this yellow leaf marker is the recessive character of monokaryon Gene Handling in the heredity, the leaf look that is the first generation of hybrid seedling of such male sterile line preparation or plant is for normal green, and the male sterile line seedling of breeding or plant are carried yellow leaf marker the time of infertility.
Advantage of the present invention is: the rice sterile line that carries yellow leaf marker with employing is a core, realize monitoring effectively each link of paddy rice plantation, carry out " dual " efficient impurities removal, promptly in numerous, seed farm, reject in the rice sterile line non-yellow leaf marker seedling or plant and realize that first resets assortedly, remove impure rice sterile line parent; In the land for growing field crops produces, reject carry yellow leaf marker seedling or plant realize second reset assorted.Adopt the plantation of the inventive method monitoring paddy rice, save time, the saving of labor, impurities removal efficient height can be guaranteed sterile line of hybridized rice and land for growing field crops purity of hybrid, ensures rice high yield.
Embodiment
Below further specify the present invention by instantiation.
Embodiment 1:
The whole process of the series of three-series hybrid rice plantation that can monitor may further comprise the steps:
Carry yellow leaf marker triple crossing male sterile line: the male sterile line H-LTF1 that carries the yellow mark with series of three-series hybrid rice cytoplasmic male sterile line Long Tefu A seed selection is an example.The seedling leaf look obviously different with the general rice varieties such as Long Tefu A of normal green of H-LTF1, and its seedling is to ripe whole growing stage blade yellow.The first generation of hybrid seedling of male sterile line H-LTF1 preparation or the leaf look of plant are normal green, the male sterile line seedling of breeding or the yellow of plant blade in the time of infertility.
Efficient auxiliary impurity elimination in numerous kind: the male sterile line H-LTF1 breeding that has yellow leaf marker is identical with the series of three-series hybrid rice sterile line propagation technology of common green.In male sterile line H-LTF1 when breeding,, what seedling or plant were carried the yellow mark time of infertility is purebred sub-seedling of male sterile line H-LTF1 or plant, and the seedling of other color and luster or plant are assorted strain, manually pull out immediately, with this by guaranteeing the seed purity of numerous kind of male sterile line.
Efficient auxiliary impurity elimination in the production of hybrid seeds: the male sterile line H-LTF1 production of hybrid seeds of carrying yellow leaf marker is identical with common green series of three-series hybrid rice sterile lines seed making technology.During the male sterile line H-LTF1 production of hybrid seeds, what seedling or plant were carried the yellow mark time of infertility is purebred sub-seedling of male sterile line H-LTF1 or plant, the seedling of other color and luster or plant are assorted strain, manually pull out immediately, improve the purity of a hybridization generation by the purity that guarantees male sterile line with this.Impurity elimination is protected pure in the field planting: when utilizing the first generation of hybrid of male sterile line H-LTF1 preparation in the plantation, observing seedling or plant is normal green true hybrid of then preparing for H-LTF1, if finding seedling or plant carries yellow leaf color marker and then is false hybrid, manually pull out immediately, to improve the purity of the land for growing field crops first generation of hybrid, ensure rice high yield.
Embodiment 2:
The whole process of the double-linear hybrid rice plantation that can monitor may further comprise the steps:
Carrying yellow leaf marker two is rice sterile line: extensively accounting for the male sterile line H-GZ1 that the 63S seed selection carries yellow mark with the double-linear hybrid rice photo-thermo-sensitive genic male sterile line is example.The seedling leaf look of H-GZ1 is with normal green extensively to account for general rice varieties such as 63S obviously different, and its seedling is to ripe whole growing stage blade yellow.The first generation of hybrid seedling of male sterile line H-GZ1 preparation or the leaf look of plant are normal green, the male sterile line seedling of breeding or plant blade in time of infertility yellow.
Efficient auxiliary impurity elimination in numerous kind: the male sterile line H-GZ1 breeding that has yellow leaf marker is identical with the double-linear hybrid rice sterile line propagation technology of common green.In male sterile line H-GZ1 when breeding,, what seedling or plant were carried yellow mark the time of infertility is purebred sub-seedling of male sterile line H-GZ1 or plant, and the seedling of other color and luster or plant are assorted strain, manually pull out immediately, with this by guaranteeing the seed purity of numerous kind of male sterile line.
Efficient auxiliary impurity elimination in the production of hybrid seeds: the male sterile line H-GZ1 production of hybrid seeds of carrying yellow leaf marker is identical with common green rice sterile lines seed making technology.During the male sterile line H-GZ1 production of hybrid seeds, what seedling or plant were carried yellow mark the time of infertility is purebred sub-seedling of male sterile line H-GZ1 or plant, the seedling of other color and luster or plant are assorted strain, manually pull out immediately, improve the purity of a hybridization generation by the purity that guarantees male sterile line with this.Impurity elimination is protected pure in the field planting: when utilizing the first generation of hybrid of male sterile line H-GZ1 preparation in the plantation, observing seedling or plant is normal green true hybrid of then preparing for H-GZ1, if finding seedling or plant carries yellow mark and then is false hybrid, manually pull out immediately, to improve the purity of the land for growing field crops first generation of hybrid, ensure rice high yield.
