Relationship of microsatellite molecular markers with morphophonological traits in rice under flooding conditions and drought stress

Rice is one of the most important crops in the world. Also, It is the main source of food and carbohydrates in the world. In this research, the relationship between the characteristics of 90 rice genotypes (Traditional and improved) with 11 SSR markers evaluated. This research was conducted as a lattice design with three replications in 2015-2016 at Gonbad Kavous University under normal and drought conditions. Multiple regression analysis between measured traits and SSR markers showed a significant relationship between data. The results of cluster analysis for agricultural traits in normal and drought stress genotypes were divided into four and three groups. The results of multiple regression analysis showed that the number of secondary branches and fertility, the most percentage of variation of explanation of yield variation, under normal and drought conditions, respectively. The results of this research can be used for breeding programs and selection of suitable and tolerant cultivar.
