Role of rye chromosome 2R from wheat-rye substitution line 2R(2D)1 (Triticum aestivum L. cv. Saratovskaya 29-Secale cereale L. cv. Onokhoiskaya) in genetic regulation of meiotic restitution in wheat-rye polyhaploids

Role of rye chromosome 2R from wheat-rye substitution line 2R(2D)1 (Triticum aestivum L. cv.... A study was made of the role of rye chromosome 2R from the wheat-rye substitution line 2R(2D)1 (Triticum aestivum L. cv. Saratovskaya 29-Secale cereale L. cv. Onokhoiskaya) in genetic regulation of meiotic restitution in wheat-rye polyhaploids 2R(2D)1 × S. cereale L. cv. Onokhoiskaya. Rye chromosome 2R proved to affect the completeness of the meiotic program, suppressing the formation of restitution gametes. This was evident from the reductional division of univalent chromosomes in AI and the occurrence of the second meiotic division. The interrelationships between the type of chromosome division in AI and the two-step character of meiosis are discussed. The structural and functional organization of the centromeric regions of chromosomes undergoing reductional division is assumed to determine the two-step character of division. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
