Abstract

Yield and quality of carrot seed were not affected by the mother root size used. However, the umbel position had significant influence on all the parameters used to evaluate the seed yield and quality except seed water content, which gave no significant response to the umbel order. Primary umbels resulted in better seed quality followed by the secondary umbels and whole plant, while tertiary umbels gave poor quality seed. All the seed yield and quality parameters studied also differed significantly for the interaction between mother root size and umbel order. Growth and yield of resulting roots were also not affected by the mother root size but were significantly influenced by the umbel order and its interaction with root size, indicating the supremacy of primary and secondary umbels on whole plant and tertiary umbels.
