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.
