The Webb Special tomato has exceptionally high pigment content. Thompson (1955) reported that this was conditioned by the combined effect of two genes hp\1 and hp\2. High pigment plants can be readily classified by several characteristics including brittle stems, darker color of stems and immture fruit, and intense color of the cut, ripe fruit. The only cross in which Thompson reported a dihybrid ratio was Webb special x Orange King. This cross gave 94 normal to 8 high pigment plants--a ratio of 11.75:1. The following ratios usually based on 45 plants, are some of those that have been obtained at Vineland 36.0:1, 10.1:1, 10.0:1, 9.8:1, 5.3:1, 5.1:1, 4.9:1., 4.6:1, 4.2:1 -----2.2:1, 2.1:1, 2.0:1, and 1.4:1. Since 1955 we have obtained 1750 normal and 496 high pigment plants--a ratio of 3.53:1. High pigment seedlings usually take longer to emerge than normal seedlings, subsequent growth is slower and mortality is higher. Accordingly it is proposed that the symbol for high pigment be hp instead of hp\1 + hp\2.
