Heritability and genetic correlations of forage yield traits in alfalfa (Medicago sativa L .) for central valley of Mexico

摘要：

Alfalfa, originally from Iran and the Trans‐Caucasian region of Asia, is now found worldwide, because of its ability to survive a wide range of temperate climates and varying moisture levels and soil types.Highland Central Valley of Mexico includes the state of Hidalgo, Mexico, Puebla, Queretaro and Tlaxcala, and alfalfa is the fifth agro‐economical crop, widely used for dairy and beef cattle and sheep feeding under harvesting or grazing conditions.However, no cultivars evaluation and breeding program exists for this region, and our task is to screen and genetically characterize novel germplasm highly adapted, persistent and yielder to Highland Central Valley of Mexico (Alarcon‐Zuniga, 2007).
