Abstract

YOKOMIZO, Gilberto K.  and  VELLO, Natal A.. Physiological quality in seeds obtained by topcrosses between vegetable soybean and grain type. Braz. arch. biol. technol. [online]. 2000, vol.43, n.5, pp. 469-473. ISSN 1516-8913.  http://dx.doi.org/10.1590/S1516-89132000000500004.

Attempts were made to study the gene introgression for high physiological quality from adapted cultivars in the vegetable soybean (exotic). Promising results were obtained for all topocrosses, with increased in germination percentage in majority. General mean of the germination percentage in topcrosses with large seeds exotic parental showed an increase from 28 to 46%, and topcrosses with small seeds exotic parental, from 54 up to 60%, both cases compared to self pollinated exotic parental. Related to variance, the topcrosses showed higher values than the self pollinated exotic parental, showing to be possible the selecion of promising materials.

Keywords : Soybean; Glycine max; topcross; physiological quality in seeds; vegetable soybean.
