Disturbances in meiosis in mutants of wheat obtained after treatment with chemical mutagens



Disturbances in meiosis in mutants of wheat obtained after treatment with chemical mutagens



Khim supermutageny v selektsii: 218-222



The results are given of a cytogenetic analysis of microsporogenesis in the spring variety Norroena and in hybrids obtained by crossing M5 mutants induced by N-nitroso-N-methylurea with the initial variety. At all stages of meiosis the percentage of disturbances in the hybrids was markedly higher than in the control. The differences were particularly marked in the frequency of cells with univalents and multivalents at metaphase I.
