The effect of rye B-chromosomes in wheat-rye hybrids
[EN] Meiotic pairing of wheat-rye hybrids with and without rye B-chromosomes was analysed in two different situations. The first using two durum wheat cultivars and the other when a ph mutant of Triticum aestivum was used. In the hybrids implicating durum wheat the B-chromosomes effect was variable...

| Resumo: | [EN] Meiotic pairing of wheat-rye hybrids with and without rye B-chromosomes was analysed in two different situations. The first using two durum wheat cultivars and the other when a ph mutant of Triticum aestivum was used. In the hybrids implicating durum wheat the B-chromosomes effect was variable in relation to the cultivar utilised. Moreover, B-chromosomes inhibited homoeologous pairing in hybrids involving ph mutant. |
