Meiotic chromosome behaviour in Triticum durum, Triticum dicoccum and Triticum polonicum hybrids

Meiotic chromosome behaviour in Triticum durum, Triticum dicoccum and Triticum polonicum hybrids

Biovigyanam 15(1): 33-38

Two cultivated wheats, T. durum N59 and T. dicoccum KDH, were crossed with T. polonicum F234. Chromosome pairing at metaphase I resulted in 14 bivalents for both the parents and F1 hybrids. The total chiasmata frequency at diplotene and metaphase I was greatest in T. durum N59. The highest chiasmata terminalization was shown by T. polonicum F234 at diplotene and by T. durum N59 at metaphase I.
