The condition of the pecan in Argentina
The pecan, Carya illinoinensis ((Wangenh.) K. Koch) is a native species from North America and mainly cultivated in that subcontinent. In Argentina, it was introduced in the 19th century. There were sporadic attempts of production but only recently, its commercial cultivation has begun. Currently, research projects in pecan exist in the National Institute of Agricultural Technology (INTA) and one of these projects has incorporated cultivars from the USDA-ARS Pecan Breeding and Genetics Program. INTA participated in the preparation of the species descriptor of the International Union for the Protection of New Plants Varieties (UPOV). Cultivars were identified using single sequence repeats (SSRs) markers technique. Agroclimatic and soil maps have been developed, determining optimal and marginal regions for pecan cultivation. Fertilization response trials have been carried out at the rootstock stage and with trees in production. Pests and diseases of pecan were identified. There is a network of cultivars trials covering different types of climate: subtropical, humid temperate, warm semi-arid and cold semi-arid. The commercial crop of the pecan in the country has grown exponentially in the last years, and there are orchards in 10 provinces of Argentina. Currently, it is estimated that 8,000 ha of orchards are available, most of them of young age. The estimated annual production for 2019 was 2,500 t year-1. Part of that production is exported.
