CARROLL P. WILSIE IN the breeding of forage crops an evaluation of individual plant selections is highly important. Propagation of selections as clones and determination of seedling progeny performance are fwo of the methods widely used. The evaluation of open-pollination progenies probably is the most popular progeny test, and includes the use of seed harvested from a specifically designed polycross nursery (isolated), where male parentage is restricted to the lines represented in the nursery, or more simply, seed harvested from openpollinated plant selections occurring in any general breeding nursery, variety plot, or field planting. Random pollination is desired, but whether actually achieved may depend on many factors, including dates of blooming, size and shape of plots, degree of randomization, isolation from other alfalfa, and possibly the differential attractiveness of certain genotypes to pollinating insects.
