Evaluation of the average performance of topcrosses among food and grain type soybean
The food type soybean (exotic) are, in general, non-adapted to the Brazilian growing conditions. A breeding strategy to develop adapted food type soybean should involve crossing exotic with the available grain type genotypes. We evaluated the performance of topcrosses among food type and grain type soybeans. Best progenies showed different performance rates in each environment and they were not always the same in the different environments and joint analysis of lodging (L), plant height at maturity (PHM) and agronomic value (AV) was essential to avoid selection of plants with good performance for one trait and bad for another.) Piracicaba autumn environment (PA) caused low individual plant yield performance (IPY), and consequently, cultivation was not economically viable in this period. Best progenies presented appropriate trait averages for inclusion in the category of vegetable soybean in all evaluated environments.
