Lutescent - 2, l\2

Kerr, E. A.

This mutant arose in a commercial field of Longred tomatoes. It is completely fertile and closely resembles the mutant formerly known as lutescent. (It is proposed that lutescent in group VI should now be designated lutescent - l and assigned the symbol l\1). The fruits of both l\1, and l\2, have a yellowish unripe color and there is premature yellowing of the leaves beginning at the base of the plant. It is possible that l\1 is more severe in its effects than l\2. The cross l\1 x l\2 gives a normal F1 and a 9:6 ratio in F2. Seeds with l\1 l\1 l\2 l\2 genotype germinate but the plants usually die before producing true leaves. Preliminary tests indicate that l\2 is linked with u, H and t in group VII.
