Abstract

Farmers from the district of São Pedro de Joselândia, belonging to the municipality of Barão de Melgaço, Pantanal of Mato Grosso, have been cultivating for some time two rice plant materials and three types of beans that, according to them, are not commercial. For this reason, the objective of this work was to test the originality of the materials by means of genetic and morphological characterization in order to identify whether the nature of the subsamples would be effectively traditional or whether they are varieties already known in the market. Morphological analyzes of the cultivated plants (phenotypic characteristics, cycle and flowering) and seed of the rice subsamples, hereinafter called Agulhinha Vermelho and Branquinho and of the Amarelinho, Rosinha and Roxinho subsamples were performed. Also, the evaluation of distribution of comparative genetic variability with other materials of the same species, already cataloged, was determined. The subsamples were characterized as traditional varieties different from those already cataloged and they are not found in the Nuclear Collection of Rice and Beans of the Brazilian Agricultural Research Corporation (Embrapa). They have distinct morphological characteristics, being potential species for use in the market of new technologies. This should guarantee to the residents of that community that they are breeders of specific materials of cultural heritage adapted to the local conditions.
