Adoção de cultivares de algodão no Estado do Mato Grosso, nas safras 2009/10 à 2014/15

Abstract

The current abstract is the result of the reality of facts that happened to the cotton culture in the State of Mato Grosso. The abstract was written with the purpose to present the cotton culture area from the 2009/10 to 2014/15 harvest seasons. To better present this abstract, the Market Share of each major and retail cotton seed company was evaluated and inside each one of their cultivars, and those cultivars that were substituted and, or, derivated through introgression or even through other transformation methods to GMO (s). It was also necessary to know the planting method to calculate the demand of seeds, parallel to that, through the seed utilization rate, it was estimated the amount of seeds saved according to mathematic difference. To speed the collection and compilation of data, the State was divided in seven regions: 1 Center (based in Campo Verde), 2 Eastern Central (based in Primavera do Leste), 3 Northern Central (based in Lucas do Rio Verde), 4 North (Sorriso), 5 Mid-Northern (Campo Novo do Parecis), 6 Northwest (Sapezal) and 7 South (Rondonópolis). The veracity of this study is due to a work done on each harvest season, in every section for each cultivar, planting distance and time in which cotton was cultivated in the State of Mato Grosso. Through the presented data on the tables and graphics we can see the evolution of the cotton culture, as well as the new cotton cultivars, cultivars with the GMO technology and also the ones derivated from the conventional cultivars. Along with the release of the GMO cotton cultivars and a more refined level of technology, each farmer complied to a planned and programed planting system to the subsequent cultures. The breeders of the private sector dominated the cotton cultivars market share for the last harvest seasons. Two breeders have the right of more than 80% of the cotton seeds market share in the state of Mato Grosso. There is a very small relation between the number of chosen cultivars and the number of released cultivars by the farmers.
