Prebreeding selection of rice with colored pericarp based on genotyping Rc and Pb genes

Prebreeding selection of rice with colored pericarp based on genotyping Rc and Pb genes The research was aimed at developing prebreeding resources of Kazakhstan rice varieties with colored pericarp for breeding. During the study, hybrid analysis of inheritance of the trait “colored pericarp” in breeding material used for the work was performed. Rice genotypes with colored pericarp, as well as white rice varieties possessing important breeding traits and maturing under conditions of the republic, were selected from the collection of the Institute of Plant Biology and Biotechnology, Republic of Kazakhstan. Identification of allelic status of Rc (red pericarp) and Pb (anthocyanin pericarp) genes was performed for selected samples using the PCR method. When selecting parental forms for crossing, foreign rice varieties with colored pericarp (Rubin, Mavr, Black rice, etc.) were used as recipient forms. As donors, we used local white rice varieties of Kazakhstan breeding adapted to the soil and climate conditions of rice growing regions (Madina, Marzhan, Bakanasskiy, PakLi) as well as foreign varieties. The ability to set hybrid caryopses and the percentage of sterility were determined in obtained F1 rice hybrids. As a result, the most promising prebreeding material was selected, which will be used for breeding Kazakhstan rice varieties with colored pericarp. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The research was aimed at developing prebreeding resources of Kazakhstan rice varieties with colored pericarp for breeding. During the study, hybrid analysis of inheritance of the trait “colored pericarp” in breeding material used for the work was performed. Rice genotypes with colored pericarp, as well as white rice varieties possessing important breeding traits and maturing under conditions of the republic, were selected from the collection of the Institute of Plant Biology and Biotechnology, Republic of Kazakhstan. Identification of allelic status of Rc (red pericarp) and Pb (anthocyanin pericarp) genes was performed for selected samples using the PCR method. When selecting parental forms for crossing, foreign rice varieties with colored pericarp (Rubin, Mavr, Black rice, etc.) were used as recipient forms. As donors, we used local white rice varieties of Kazakhstan breeding adapted to the soil and climate conditions of rice growing regions (Madina, Marzhan, Bakanasskiy, PakLi) as well as foreign varieties. The ability to set hybrid caryopses and the percentage of sterility were determined in obtained F1 rice hybrids. As a result, the most promising prebreeding material was selected, which will be used for breeding Kazakhstan rice varieties with colored pericarp.
