E. de  aEffect of Ogura male-sterile cytoplasm on the performance of cabbage hybrid variety. I. Vegetative characteristics.h[electronic resource]  c1994  aCabbage hybrid seeds are commercially produced by means of self-incompatibility. This system may show some instability mainly under tropical conditions, where cytoplasmic male sterility can be an alternative approach for hybrid seeds production. However, cabbage hybrids holding Ogura male-sterile cytoplasm show some irrgularities during development. By assessing some characteristics during the growing cycle of male-sterile cabbage hybrids and comparing them to genomic similar male-fertile ones and to the most common cabbage hybrid cultivated in Brazil, it was observed that the male-sterile hybrids had the same vigour, uniformity, number of leaves, resistance to Xanthomonas campestris pv. campestris, and earliness as their male-fertile counterparts and performed better than the commercial check hybrid for some of these characteristics. Although male-sterile hybrids showed yellowing of leaves, some parental combinations succeeded in overcoming or strongly reducing this cytoplasmic effect.  acabbage  aCerrado  aRepolho  aAuto-Incompatibilidade  aBrassica oleracea var  acapitata  aHibridos  aMacho-Esterilidade  aMale-Sterility1 aGIORDANO, L. de B.  tEuphyticagv. 76, p. 117-123, 1994.
