Coadaptation role in wheat breeding for adaptability and productivity under conditions of climate fluctuation amplification

Аннотация

The opportunity to create the high-yielding cultivars adapted to negative natural factors in the steppe zone of the River Don at the weather fluctuation amplification through coadaptation across a range of stages has been proven. At the beginning of crossbreeding, the ecologically remote forms were used to create the initial material for further selection with the gene complexes coadapted to the local conditions. Then, their subsequent involvement into hybridization and the use of populations capable of long-term morphogenesis based on recombination and transgressions can offer the opportunity to increase the potential productivity growth and to cope with the negative effects of climate amplification.
