| Abstract: | Objective]The main purpose of this research was to study the cotton physiological indices under cold stress and to determine specific molecule mark primers.Method]Thirty kinds of cotton materials which have good agronomy characters and resist different cold temperatures were dealt with 3℃cold stress during 24 hours.Seven physiological indices were tested before and after the cold stress;a series of gene sequences related to cold resistance were found from Genbank,and primers were designed by biological software Oligo6.0,and the molecule marks of peculiar primer about resistant cold were selected.Result]Three physiological indices related to cotton cold resistance were identified,two pairs of specific molecule marks related to cotton cold resistance were screened,and five cold resistant materials were selected.Conclusion]A system of cotton cold resistant identification by using physiological indices that were combined with the molecule marks were set up. |
