The Use of DNA Markers in Rice Breeding for Blast Resistance and Submergence Tolerance as a Weed Control Factor
Elena Dubina, Pavel Kostylev, Yulia Makukha, Margarita Ruban
TL;DR
This paper describes how DNA markers are used to breed rice varieties that resist blast disease and tolerate submergence, improving yields and reducing costs.
Contribution
The paper introduces effective DNA marker systems for blast resistance (Pi) and submergence tolerance (Sub1A) in rice breeding.
Findings
DNA markers enabled precise selection of hybrid rice plants with blast resistance and submergence tolerance genes.
Automated detection of Pi-ta and Pi-b genes reduced DNA analysis workload during breeding.
New rice varieties like Al’yans and Pirouette increased yields by 0.64–2.2 t/ha compared to standards.
Abstract
Diseases and weeds occupy a leading place among the factors limiting the yield of agricultural crops, including rice. These factors can be overcome through the use of chemical protective agents, as well as through the creation and introduction into agricultural production of rice varieties resistant to these stressors. The use of DNA marking technologies for target genes of economically valuable traits in the creation of promising varieties allows not only for the identification of genes but also the monitoring of their transmission during crosses and the selection of breeding-valuable genotypes with genes of interest. In addition, this ensures a reduction in the volume of breeding nurseries, as well as time and material costs during variety modeling, and rapid rotation of new high-yield varieties with specified characteristics. We have selected effective marker systems based on the use…
