Description
Lucerne, pure or as a component of mixtures, is the forage more used in many regions of Argentine. In the central part of Santa Fe province it is the basis of feeding in the milk production systems. The diffusion of this species was done by mean of populations, that at the beginning of this century produced forage of high yield, quality and good persistency. Later, the area ofland cultivated fluctuated, characterized by periods of diminishing and recovery. From 1969 the appearance of Pea aphid (Acyrthosiphum pisum) gave rise to a critical situation. The solution to this problem was the introduction of resistant cultivars and the incorporation of resistance to the national genotypes. At the same time this cultivars carried the condition of different winter dormancy class and it made possible the use of lucerne in periods of low temperatures. The objective of this work was to evaluate three varieties of lucerne: Kanza, Wl-318 and WL-514 with different winter dormancy class concerning production and seasonal distribution of the forage.

Varieties Evaluation of Lucerne (Medicago sativa) with Different Winter Dormancy Class
