ABSTRACT:
An alfalfa product, hybrids and non-hybrids, and a method for synthesizing an alfalfa product having increased uniformity for preselected traits having improved uniformity of one or more selected traits, including flowering dates, flower frequency, maturity rate, growth rate, fall dormancy and winterhardiness. The alfalfa product may also include improved predictability of these traits. A scheduled harvest system may be established using two or more varieties of the alfalfa product having different and predictable mean flowering dates. The scheduled harvest system may be designed to allow for harvesting of alfalfa varieties at maximum relative feeding value. The method may be used to synthesize an alfalfa product having one or more predetermined traits. The method selects germplasm, including a cytoplasmic male sterile line, a genetic male sterile line, a maintainer line, a restorer line and a line having normal cytoplasm, having agronomically desirable traits. Plants grown from the germplasm are classified and grouped for predetermined traits at different stages of testing and seed increase. The method selects genetically desirable plants having the predetermined traits for seed increase.
