Abstract
Extensive karyological analysis including determination of somatic chromosome number, total chromosome length and volume and estimation of 4C DNA amount were carried out on 8 different varieties of Coriandrum sativum L. A significant variation in nuclear DNA amount was recorded in the varietal level. The structural alteration of chromosome as well as loss or addition of highly repetitive sequences in the genome have played a vital role in intervarietal DNA variation. The absence of wide differences in nuclear DNA content in the varietal level indicate a close relationship between them.
