Summary
Leaf length divided by leaf width, (L/W), was studied as a criterion for differentiating between nucellar and zygotic citrus seedlings. Progeny of crosses of the variety ‘King’ as a seedparent (known to produce both nucellar and zygotic seedlings) fell into two classes: one with L/W similar to ‘King’ and the other midway between ‘King’ and the pollen parent. In several zygotic seedling populations, population means were intermediate between those of the parents. L/W can be an effective criterion for differentiating between nucellar and zygotic citrus seedlings where the parents differ appreciably.
