Morphological and cytological researches of artificial polyploids of coriander Coriandrum sativum L

Morphological features of coriander tetraploids are studied. It is established that tetraploid plants have the increased sizes of leaf blades of composite leaves and increased petioles length. Reproductive organs of early (С1-С2) tetraploids are characterized by partial flower sterility, reduced quantity of pollen and its lowered fertility. Seedsetting rate in tetraploid umbels is lowered. Tetraploid fruits have larger sizes in comparison with diploid forms. After restoration and stabilization of fertility, tetraploid and reploid coriander forms kept large-leaves and large-fruitiness can be used as a parental material for coriander breeding on these traits.
