GENETICS OF FLOWER COLOUR AND GLOSSINESS IN INDIAN MUSTARD (BRASSICA JUNCEA (COSS)

Published on

Genetics of flower colour and glossiness of foliage was studied in the crosses involving
four parents, RWH-l (white flowed; RC 1425 (glossy), and RH 30 and RH 7859 (nonglossy
and yellow flowers). A segregation ratio of 3 nonglossy : 1 glossy in F2 generations of
different crosses indicated that glossiness is controlled by a single recessive gene. This was
confirmed by studying the back-cross generations. Similarly in crosses of yellow and white
flower parents a segregation ratio of 15 yellow: 1 white flower in F2 generations, indicated
thatflowercolouris controlled by two genes where white flower colouris double recessive.
This was also confirmed by studying the back-cross generations.
