Meiotic irregularities in Triticum x Agro-pyron hybrids

, : Meiotic irregularities in Triticum x Agro-pyron hybrids. Abst. Pap. XI Internat. bot. Congr, 193 p

durum (2n = 28) x A. intermedium (2n = 42) amphidiploid hybrids were back crossed to A. intermedium. The number of bivalents in the PMCs of the BC1 lines ranged from 14 to 21, and the number of univalents from 9 to 22. Pollen sterility estimates ranged from 12.5% to 98.3%.

Background: The origin of the nucleus is a central problem about the origin of eukaryotes. The common ancestry of nuclear pore complexes (NPC) and vesicle coating complexes indicates that the nucleus evolved via the modification of a pre-existing...
