Genetics of flower color in Linum grandiflorum Desf.

Published on

A study was conduced to know the mode of inheritance of
different colors of corolla petals in Linum grandiflorum
Desf. Four pure lines with crimson, copper, pink and apricot
color of the flower were crossed among themselves. The
F1 hybrids of crimson x copper, crimson x pink, copper x
apricot and pink x apricot were made.The crimson color
completely dominates over copper color, while copper color
dominates over apricot color.The segregation pattern in F2
populations of each cross was studied through Chi-square
test to test the significance of observed classes. The
genotype of the four lines proposed are- Cf-Af-Si(crimson
color), cfcfAf-Si-(copper color), Cf-Af-sisi (pink color) and
cfcfafafSi-(apricot color). The siallele in the homozygous
state equally suppresses the dominant and recessive alleles
of af gene. The suppression of corolla color in certain
genotypes makes the phenot
