POLYPLOIDY IN SOLANACEOUS CROPS

Nadeem Ataurrehman Kazi

Abstract


Solanacae is an economically important including number of important Crops Viz., Tomato, Potato, Chilli, Bell pepper, Egg Plant, Tomatilo. Polyploids are valuable sources of genes for disease resistance and stress tolerance and genetic variation. Polyploidy or chromosome doubling induced changes in morphology and cytology. Morphological changes included change in fruit and flower shape, size, number of leaves or branches and even abnormalities were reported.
Polyploidy was found to be induced by colchicine, oryzalin, colcemid, trifluralin etc. Chromosome doubling was achieved by different concentrations of colchicine. Review of polyploidy in Solanaceous crops Viz., Tomato, Chilli, Chilli Pepper, Potato, Tomatillo, Nicotina, African Nightshade, Datura and Eggplant was undertaken.
