INHERITANCE OF ROOT CHARACTERS IN TURNIP (BRASSICA RAPA L.)

Published on

Inheritance of root colour in turnip (Brassiea rapa L.) was studied in nine crosses involving
five parents. Purple root colour was dominant over pink, partially purple and white root
colour, and was under the control of two genes P and C. These two genes in double
dominant state produce purple roots. The genotype of purple parent was thus tentatively
designated as PPCC. The pink and partially purple root colours were dominant over white
and they were under the control of single dominant gene P and C, respectively. Genotype
PPcc produces pink root and ppCC partially purple roots. White roots are produced
in double recessive homozygotes: ppec. Root shape was studied in two crosses
involving round and flat round rooted parents. The Fl generation showed dominance of
round shape over flat round as a monogenic trait. The gene symbol R is proposed for this
character.
