Description
The objective of our breeding program is to build alfalfa (Medicago satia L.) varieties, having good vigor and persistence, high protein level, and low ,aponin content. The: breeding method utilizes a selfing phase combined with selection in competitive conditions. Leaf-saponin content was analyzed by the Tn'choderma viridc bioassay. Parent populations (cv. Leonicena and Cantoni), S0, S1., and S2, families :1 were evaluated 11ndcr competitive and &equcnt culling conditions. In both populations, some S1, families yield more than their respective S1 family. Vuiatioo in yield and mortality increased with the level of selfing, and 1ome S2 families showed lower minimum values of mortality than the S2 familin. The persistent S, families were the earliest to flower. A positive correlation existed between S, family, and S0 mother plant. and between S2 families and S, mother plants, Yield depression is a parameter that depends to some extent on the experimental conditions of plant density and cutting &equc:ncy.
