GENETICAL AND EVOLUTIONARY SIGNIFICANCE OF SOME JUVENILE AND OTHER VEGETATIVE ATTRIBUTES IN TURNIP..

The present study shown that there is significant intervarietal variation in seed germination, mean hypocotyl length, mean cotyledon area, and relative width of cotyledon, which can be related to genotypic differences. In terms of these characteristics, a comparison with F1 intervarietal hybrids reveals heterosis as a result of increased heterozygosity in them. Furthermore, it has been demonstrated that the colour of turnip roots is inherited monogenically, whereas the length of the hypocotyl is controlled by a polygenic system. Early blooming Asian kinds are advanced, whilst late blooming European species are rudimentary. There was also a negative association between plant height and days to flower.
