Abstract

In the present paper it has been shown that there is considerable intervarietal variation in seed germination, mean hypocotyl length,  mean cotyledon area and relative width of cotyledon which may be attributed to their genotypic peculiarities.  A comparison with F1 intervarietal hybrids with regard to these characters indicates heterosis as a result of increased heterozygosity in them.  Besides, it has been shown that in turnip root colour is inherited monogenically while the hypocotyllength is under the control of a polygenic system.  The early flowring Asiatic varieties are advanced while late flowering European  varieties are primitive.  A negative correlation between plant height and days to flower was also visualized.
