Sunflower varietal purity of SSR analysis
abstract
» 英语
Has long been a large number of promotion new sunflower hybrids and varieties identification is an indispensable key step in production. Varietal purity identification is the traditional way of field planting, by observing the morphological characteristics to distinguish between different varieties. Breeding technology progress in recent years, gradually converge, the morphological characteristics of the different varieties of through the difficulty of the morphological characteristics of different varieties more and more big. SSR (Simple Sequence Repeats) marker is developed in recent years, DNA molecular markers, SSR's biggest advantage is that the amplification product after polyacrylamide gel electrophoresis separation, can be observed on the electrophoresis gel block to the length of a single base differences. So the amplification of SSR fragments of high polymorphism, can get a lot of genetic information from the result of the experiment, and has good stability and reproducibility. Thus SSR markers is a kind of ideal detection sunflower varietal purity of molecular markers. This study from sunflower total DNA extraction, PCR amplification, electrophoresis detecting aspects such as research, with new kwai 19 as materials, the screening of molecular markers for 40 SSR primers and repetition, obtained able to distinguish between male parent, female parent and hybrid SSR primers mark 399. And finally established a set of applicable Yu Xinkui 19 varieties purity identification technology system.
