Evaluation of the average performance of topcrosses among food and grain type soybean 52
Yokomizo,Gilberto K.; Vello,Natal A..
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...

Preliminar evaluation of performance in topcrosses between vegetable type and grain type soybean 52
Yokomizo,Gilberto K.; Vello,Natal A.; Nekastchalow,Marcos C..
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.
