Green flesh, gf
The fruit of a late-blight resistant tomato obtained from the Central Experimental Farm, Ottawa, as Philippine #2 is much fasciated and, when ripe, is a dirty purplish brown color. This ripe fruit color is recessive in the F1 and gives monogenic F2 segregation ratios. The fruit color is caused by a failure of the chlorophyll to break down when the lycopene is formed. Hence both chlorofphyll and lycopene are present in the mature fruit. Since r r fruits do not form lycopene, fruits of r r gf gf genotype have a green color when mature. Preliminary tests indicate that gf may be linked with al in group VI and also with the type of fasciation found in Philippine #2.
