Abstract
The wheat cultivar ‘BRS 277’ was developed by Embrapa (Empresa Brasileira de Pesquisa Agropecuaria), resulting from a cross between OR1 and Coker 97-33. The plant height of ‘BRS 277’ is short, frost resistance in the vegetative stage is good and resistance to leaf rust moderate.

Agricultural research in Brazil has contributed significantly to increase wheat yields and improve the quality.Genetic improvement of wheat in Brazil began in 1919, with the establishment of experimental stations in Alfredo Chaves, Rio Grande do Sul (RS), and Ponta Grossa, PR, by the Ministry of Agriculture
At that time, breeding work focused primarily on the selection of plants within progenies from seed collections of genotypes used by settlers
Summary
Agricultural research in Brazil has contributed significantly to increase wheat yields and improve the quality. As a result of these early efforts, the cultivar Frontana was released for cultivation in 1940 (Beckman 1965) This cultivar is still considered the greatest national contribution to wheat breeding worldwide, mainly due to the resistance to shattering, pre-harvest sprouting and to rust in adult plants (Sousa 2004). Wheat breeding developed significantly in the 70’s in Brazil, leading to the establishment of several governmental and private research centers in southern Brazil, mainly the National Wheat Research Center (nowadays Embrapa Trigo in Passo Fundo, RS) This supported the expansion of cereal cultivation and the foundation of several cooperatives. The wheat breeding program of Embrapa aims to make cultivars available to the cereal production chain that have competitive agronomic performance and are appropriate for the different segments of milling industry, in terms of technological quality and suitability. This study aimed to disseminate information about the traits of the new wheat cultivar BRS 277 to the scientific community
