Combining gene and genome mutations in maize breeding for grain protein content and quality

Abstract

This paper presents the results of the evaluation of protein and lysine content in diploid and tetraploid maize with the o2 gene in the year of vegetation 2017. As research material we used diploid and tetraploid forms with opaque2 gene belonging to two hybrids homologated in Moldova Chişiniovschi 307 PL and Chisiniovschi 401 L. The tetraploid forms were obtained by colchicinization at the Department of Plant Biology of the State Agrarian University of Moldova during 2010- 2011 and are maintained in populations.
