Seed yield of alfalfa (Medicago sativa L.) is important in determining the effective distribution new cultivars to farmers. Many genetic and environmental factors affect seed yield. This study was conducted explain variation induced by either conditions or cultivars. We analyzed yield, aboveground phytomass, harvest index, components for a set 12 at four locations across France each three years. Each location x year combination considered an environment. weight, number pods per inflorescence, seeds pod, mean weight were measured. Mean 801 kg ha(-1). Large found among environments. The cultivar environment interaction significant. Among environments, highly correlated with phytomass (r = 0.94) as lowest yields obtained seeding year. most adapted grazing showed yields. genetically lodging resistance -0.89) index 0.99). 12.7%. inflorescence high broad-sense heritability (0.58) correlation 0.91) 0.96). Variation associated pod inflorescence. appears have strong association alfalfa. Environments potential also potential.
