Summary
Seven monotelotrisomics emerged spontaneously from primary trisomics of rye cv. Esto. Analyses of karyotype, of chromosome pairing in meiosis and of Giemsa banding pattern were used to identify monotelotrisomics in rye as IRS, 1RL, 3RS, 4RS, 4RL, 6RS and 7RL. Vitality and fertility were better than in primary trisomics. The extra telocentrics were well transmitted through the female gamete. Transmission through the male gamete was in all cases less than trasmission through the female gamete.
