Despite being considered a staple food on the Brazilian cuisine, as well as in other countries, common beans still have a relatively low productivity. Thus, the use of more rustic genotypes in relation to diseases and more adapted to the environmental conditions becomes essential to supply a demand of this crop. Thus, the objectives of this work were to evaluate the adaptability and stability of common bean genotypes at differentenvironmements, in addition to selecting the genotypes with greater resistance to anthracnosis and to angular leaf spot. The GGE and AMMI methods were used to estimate the adaptability and stability of the common bean genotypes whichwere evaluated in multi-environment trials conducted at different sowing times, distributed in 9 locations of Santa Catarina state, during the 2014 and 2015 , totalizing 17 environments. All trials were conducted in a randomized complete block design with four replications. A total of 28 commonbean genotypes were evaluated, being 24 linesfrom different breeding programs and four commercial cultivars, used as checks. According to the AMMI model, it was observed that the genotype CHP 97-09-15-41 is the most productive, while the LP 11-363 and CHC 01- 175-1 are the most stable genotypes. Otherwise, the GGE biplot model showed that the CHC 01-175-1 is the most stable and productive among the tested genotypes, being thus considered as the ideal genotype. The environments Chapecó (safra) and Chapecó (safrinha) were considered the most representative and discriminating environments for the evaluation and recommendation of genotypes in the studied region. The trials seeking to select genotypes with a greater resistance to anthracnosis and angular leaf spot were conducted during the agricultural years of 2014 and 2015, in the location Chapecó, Santa Catarina state. The genotype CHC 01-175-1 was 11.6% more productive than BRS Campeiro and 46.46% more productive than Pérola, due to the adjusted average of the two years of cultivation. The CHP 99-65-24 genotype showed greater sensitivity to anthracnosis in the pods, through the comparison of means test, but it did not differ statistically from the check SCS 202 Guará. The genotype TB 03-26 differed from the others genotypes in relation to the angular leaf spot. O feijão (Phaseolus vulgaris L.) é uma leguminosa de grande importância para os países em desenvolvimento. Apesar de ser considerado um alimento básico na mesa dos brasileiros, bem como em outros países, o feijoeiro ainda possui uma produtividade relativamente baixa. Desta forma, a obtenção de genótipos mais rústicos em relação a doenças e adaptados as variações ambientais, se torna fundamental para suprir a demanda produtiva. Assim, os objetivos deste trabalho foram avaliar a adaptabilidade e estabilidade de genótipos de feijão em diferentes ambientes de semeadura, além de selecionar genótipos com maior resistência à antracnose e à mancha angular. Métodos GGE e AMMI foram utilizados para estimar a adaptabilidade e estabilidade de genótipos de feijão avaliadas em ensaios multi-ambientes realizados em diferentes ambientes de semeadura, distribuídos em 9 locais do estado de Santa Catarina, durante as safras de 2014 e 2015, totalizando 17 ambientes. O delineamento experimental utilizado nos ensaios foi o de blocos ao acaso, com quatro repetições. Os tratamentos foram constituídos de 28 genótipos de feijão, sendo estes, 24 linhagens oriundas de diferentes programas de melhoramento e 4 cultivares comerciais como testemunhas. Segundo o modelo AMMI, foi observado que a linhagem CHP 97-09-15-41 é a mais produtiva, enquanto as linhagens LP 11-363 e CHC 01-175-1 são as mais estáveis. De outra forma, o modelo GGE biplot, a linhagem CHC 01-175-1, demonstrou ser a mais estável e produtiva entre as linhagens testadas, sendo assim, considerada como o genótipo ideal. Para a avaliação e recomendação de genótipos, na região de estudo, os ambientes Chapecó (safra) e Chapecó (safrinha), foram considerados os mais representativos e discriminantes. Os ensaios buscando selecionar genótipos de feijão com maior resistência à antracnose e à mancha angular, foram conduzidos durante os anos agrícolas de 2014 e 2015, no município de Chapecó, estado de Santa Catarina. O genótipo CHC 01-175-1, mostrou-se 11,6% mais produtivo que o BRS Campeiro e 46,46% mais produtivo que o Pérola, pela média ajustada dos dois anos de cultivo. O genótipo CHP 99-65-24 mostrou maior suscetibilidade à antracnose nas vagens, através do teste de agrupamento de médias, porém não diferiu estatisticamente da testemunha SCS 202 Guará. O genótipo TB 03-26, diferiu das demais em relação a mancha angular nas folhas. 2020-08-21T13:33:05Z 2020-08-21T13:33:05Z 2020-04-14 masterThesis BALDIN, Rafael Carlos.
