NO:3) as shown in Figure 1 to the partial results of 480 individual amplifications.
Whole electrophoresis results are subjected to data statistic analysis, the specific method is as follows:It is father by F2 groups single plant amplified band
This type is denoted as a, and amplified band is the b that is denoted as of maternal type, and amplified band is denoted as h, band containing male parent type and maternal type simultaneously
Pattern paste or missing be denoted as-, be equivalent to shortage of data, finally obtain the base of 480 individual 616 pair primer amplifications of F2 groups
Because of type data.For example, be a with 480 individual data that pair of primers obtains, b, h ,-, b ... ... totally 480 data are used
The data that second pair of primer obtains be b, a, h, a ,-... ... totally 480 data, totally 616 pairs of primers count respectively, gained is
The genotype data of the F2 groups.
With 3.0 softwares of MapMaker (Constructing genetic maps with MAPMAKER/EXP 3.0, S
Lincoln,M Daly,E Lander-Cambridge,MA:Whitehead Institute, 1992) carry out genetic linkage map
Spectrum is drawn, and genetic linkage map is obtained.Can determine on the genetic linkage map obtained from this 616 pairs of primers position and with millet blade
The genetic distance of color gene.
(2) assignment of genes gene mapping
It is similar with male parent type character to be denoted as a (blade edge colour pattern) according to 480 individual leaf color phenotypes, with mother
This type character is similar to be denoted as b (blade yellow type), and character occupy and is denoted as h between male parent and female parent.Obtain 480 it is individual
480 individual phenotypic datas are compared by phenotypic data with the 480 individual genotype datas obtained before, similar
Gao Ze represents the label and leaf color character close linkage, and by the leaf color assignment of genes gene mapping on genetic linkage maps.
Embodiment 6:With the verification of the molecular labeling of millet leaf color gene close linkage
1. made from embodiment 5 on the basis of genetic linkage maps, even according to the heredity with millet leaf color gene
Distance is locked, in the hereditary close linkage with millet leaf color gene apart from the location determination for being 1.6cM molecular labeling primer
(Seq ID No.2 and Seq ID No.3), and corresponding male parent sequence location is found, the sequence between upstream and downstream primer is
Molecular labeling, nucleotide sequence is as shown in Seq ID No.1.
