In search of new cultivars with differentials that better meet the needs of the cattle ranchers, crosses between five sexual plants and the apomictic accessions PM20, PM21 and Myiage were carried out at Embrapa Beef Cattle, Campo Grande, MS, Brazil. Accessions PM20 and PM21 were used to generate shorter hybrids for use under grazing and for crop-livestock integration; Myiage was used because of its ability to retain seeds.

The objective of this work was to evaluate the effects of selection for high protein on seed physiological quality and grain yield of soybean. Four populations of BC1F4 and four of F4, each from a cross between a commercial variety and a line bearing high protein seeds, were used. The high protein content selection has a tendency to affect negatively the seed physiological quality. Estimates of correlation coefficients between protein content and grain yield were mostly negative but varied among populations. It is possible to obtain lines with high protein content, keeping the grain yield and the seed physiological quality of their respective recurrent progenitors.

Use of RAPD-PCR to identify true hybrid plants from crosses between closely related progenitors

RAPD-PCR molecular markers were used to identify common bean and soybean hybrid plants derived from crosses between closely related progenitors, with no apparent phenotypic differences. Primers OP-F12 and OP-0O3 were used to identify true hybrids derived from crosses between common bean cultivars Rudá (A 285) and AN 910408, and soybean cultivars Cristalina and Bossier, respectively. Each primer generated one polymorphic DNA band which was present in the male progenitor and absent in the female progenitor. As RAPD bands are normally inherited as dominant characters, the presence of these bands in the F1 plants confirmed their status.
