Meiotic behaviour and pollen fertility in colchiploid Zea mays L

Colchicine at various concentration was given to the apical buds of maize (Zea mays L.) Plants, in order to induce tetraploidy for meiotic studies. Highly irregular meiosis in the C1 generation was revealed. These meiotic abnormalities increased pollen sterility which lead to a lower seed setting. I...

Description
Summary:Colchicine at various concentration was given to the apical buds of maize (Zea mays L.) Plants, in order to induce tetraploidy for meiotic studies. Highly irregular meiosis in the C1 generation was revealed. These meiotic abnormalities increased pollen sterility which lead to a lower seed setting. In the C2 generation the occurrence of bivalent has increased and that of multivalent has decreased. Restoration of meiotic regularities, pollen fertility.
