Preliminar evaluation of performance in topcrosses between vegetable type and grain type soybean
Studies were conducted to evaluate the performance of topcrosses between food type soybean (with tendency to low physiological quality of the seeds) with two adapted grain type, seeking to associate adequate human food characteristics with adaptability. The conclusions were: a) The best topcrosses f...

| Summary: | Studies were conducted to evaluate the performance of topcrosses between food type soybean (with tendency to low physiological quality of the seeds) with two adapted grain type, seeking to associate adequate human food characteristics with adaptability. The conclusions were: a) The best topcrosses for vegetable type soybean were obtained predominantly with ´FT-2` and for seed yield with ´Doko`; b) The evaluated topcrosses presented high sensibility to winter conditions in comparison to summer, consequently the selection process in the winter it must be avoided; c) The selection for food type soybean it must be established in adequate values between individual plant yield and one hundred seed weight.<br>A soja hortaliça, com sabor agradável, sementes grandes, destinada ao consumo humano direto, apresenta sementes com baixa qualidade fisiológica e alta sensibilidade ao fotoperíodo, sendo que para corrigir estes problemas foram realizados topocruzamentos entre soja tipo alimento com dois tipo grão adaptados, procurando associar características adequadas para alimento humano com adaptabilidade. As conclusões obtidas para estes topocruzamentos foram: a) Os melhores topocruzamentos para tipo hortaliça foram obtidos predominantemente com ´FT-2` e para produtividade de grãos com ´Doko`; b) Os topocruzamentos avaliados apresentaram alta sensibilidade as condições de inverno em comparação as de verão, com isto o processo de seleção no inverno deve ser evitado; c) A seleção para soja tipo hortaliça deve ser estabelecida em valores adequados entre a produtividade por planta individual e peso de cem sementes, evitando o processo de seleção baseado em somente um caráter. |
