Variété originaire des USA.

Origin. A cross bet'vveen Louisiana Pink and Grand Rapids Forcing, now in the sixteenth generation from the cross. Described at length in Illinois Station Bulletin 361. Vine type. Blair Forcing and Lloyd Forcing vines are so strikingly similar that it is difficult to distinguish them. This might be expected, as they originated from the same cross. The set averages about 3.3 mature fruits per cluster in the fall and 5.7 in the spring. Fruits. Red, smooth, oblate, resembling Blair Forcing very closely except for color. The seed cavities are small and vary from three to seven or more. Like Blair Forcing, the fruits are exceptionally solid, with a small core and a medium-thick rind. Lloyd Forcing is a free seeder. The fruits rarely become puffy. They were pleasantly acid under all the conditions of these tests. Under adverse conditions, such as low temperatures, insufficient light, or improper fertilization, the fruits tend to become a little rougher than in the globe-shaped varieties. However, owing to the good set these may be thinned out profitably. In the spring, under certain conditions which are not yet understood, Lloyd Forcing has a tendency to grow projections like horns at the stem end. This tendency, which has been noted in several greenhouse varieties, seems to be infrequent in the globe-shaped types and to be associated with a heavy yield. However, even after all such imperfect fruits are sorted out, the yields of Lloyd Forcing are still very superior to those of other varieties (see table, page 20). Yields. Lloyd Forcing is unquestionably the most consistently productive variety ever grown at the Illinois Station. It is so superior that it is usually used at the Station as the standard for measuring the yields of other types and varieties (see table) . Quite a number of greenhouse growers are now growing it commercially. In weight per fruit it equals lVlarglobe and Bonny Best. Use. Lloyd Forcing is suitable for both fall and spring crops. Its rapid growth and unusual vigor are important factors in cutting down costs of pruning, pollinating, etc. It will mature about 10 percent more of its crop than 1Iarglobe during the first month of picking in the fall and about 20 percent more in the spring.
