Abstract
Forestry breeding programs have yields of wood and non-timber products, and tolerance to adverse biotic and abiotic factors. The available climatic records indicate the decrease of the average rainfall of Cuba by 200 mm in the last 50 years, a trend that will increase according to the climatic scenarios, therefore having material with high yields of wood; tolerant to drought is fundamental to the forestry program 2030. The objective is to analyze advances in genetic improvement in species of the genus Acacia. From the 90 to the 2000 seven experiments were established, where eight introductory investigations were developed, one of provenances and another to obtain the hybrid. The area destined to the genre increased in six years to 65%, showing its productive relevance. This analysis led to the design of the improvement program to obtain hybrid seed that produces drought-tolerant round wood
