RESUMO:

Maise (Zea mays L) belongs to the Poaceae family to the genus zea. It constitutes a species of great economic importance, in addition to having a relevant role for traditional populations and family farming, it also has great diversity of use, ranging from human food, animal feed and raw material for agro-industries of different branches. Being an allogamous species with one of the greatest genetic variability among species of cultivated plants, the result of human selection and climatic adaptations suffered by the species over time, which allows its production in different environments all over the world. For all these attributes, maize is present in most small rural properties and, in several of them, the cultivated varieties have been maintained and cultivated throughout the generations. Usually, the maize variety is selected and maintained by these farmers for certain specific purposes of their property (human and animal food, silage production, flours) and, over time, adapted to the management and characteristics of their growing region. The practice of cultivating low-tech Creole maize often occurs on family properties, especially subsistence ones. Under these conditions, the cultivation of Creole maize results in a satisfactory productive yield, allowing the producer to make use of the selected seeds from one crop to another, through the practice of mass selection of the most vigorous plants. The present work aimed to characterize the genetic divergence by means of morphological characters of local varieties of Creole maize grown in the municipality of CarlindaMT and to work with the use of experimentation in the development of a research with high school students of E. E. Frei Caneca using a variety of Creole maize of scientific methodology. Ten varieties acquired from the producers were selected and 16 morpho-agronomic characters were evaluated, eight quantitative and eight qualitative. For the characterization of genetic diversity, the Principal Component Analysis method was used, based on the measures of dissimilarities obtained with the Mahalanobis Distance, using the computational resource of the GENES program. Principal component analyzes were useful to indicate the xii characteristics that most influenced the response variable. The characters that most discriminated the varieties were ear height, number of grain rows and average ear diameter. The graphic dispersion based on the first two main components revealed the formation of two distinct groups among the ten evaluated varieties, showing the intraspecific genetic diversity of the genotypes. The use of experimentation in the classroom, with research involving Creole maize, based on scientific methods, was carried out with high school students. The activities carried out through the development of this experiment with theoretical and practical activities in a school environment allowed the student to develop, in addition to skills related to understanding the content, a critical awareness regarding the preservation of the environment with the use of sustainable production practices, in addition to allow the development of practical work. The study was carried out at the Frei Caneca State School, in the municipality of Carlinda - MT, from April to July 2019. The development of the research took place in meetings with theoretical and practical activities and whose final objective was to develop with the participants a scientific work with the evaluation of pollen viability and post meiotic index in a variety of Creole maize that was planted in the schoolyard for this purpose, also included the application of a pre-questionnaire and at the end a post-questionnaire with the objective of assessing learning during the project development process. The activities carried out through the development of this experiment with theoretical and practical activities in a school environment allow the student to develop, in addition to skills related to understanding the content, a critical awareness regarding the preservation of the environment with the use of sustainable production practices, in addition to allow the development of practical work. The use of knowledge and methodology produced in the scientific environment in the teaching of biology contents enabled, in addition to formal and non-formal educational practice and its complementarity and the development of scientific education / culture, also contributed to the strengthening of teamwork, companionship and greater interaction between the segments involved in the project, developing a strategy that contributed to popularize science, enrich formal education and reinforce alternative modes of learning.
