8.For the utilization in hybrid seed production, it is important to research the Rf genes. In this study microsatellite markers were used to characterize fertility restorer genes of a restorer line of PR143 for T-type CMS in hexaploid wheat. The F2 populations of BAU 95A/PR143 were used to map the nuclear fertility restorer (Rf) gene for T. timopheevi (T-type) cytoplasmic male sterility (CMS).
9.150 F_1 individuals were scored for marker polymorphisms. A high density genetic map was constructed using Joinmap3.0 setting CP (cross pollination population) type data based on the AFLP markers generated by 50 EcoRI/MseI primer pairs, 333 AFLP markers located on 14 linkage groups, with an average distance of 3.9cM between adjacent markers, covering a total distance of 1237.4cM of Chinese jujube genome.
10.Based on the 1∶100000 landcover map of the Heihe river basin in 2000 and the global 25-type classification systems,the 30 s landcover map of the Heihe river basin(Heihe data for short) was brought out combined with the 1∶1000000 vegetation classification map,which is the same classification format with global 30 s landcover data(USGS data for short) brought forward by Loveland at the beginning of 1990′s.
