Male sterility is documented in many plant species. When a plant is male-sterile, an open pollination by a genetically diverse pollinator is possible. This study investigates the combined effects of nonrestored cytoplasmic male sterility (CMS) and xenia (cross-pollination) on the grain yield of seven European flint x dent single-cross maize (Zea mays L.) hybrids. Open pollinated field experiments were conducted in six environments in Switzerland in 1998 and 1999; the design was a split-plot...

Combining cytoplasmic male sterility and xenia increases grain yield of maize hybrids. (Crop Breeding, Genetics & Cytology).
Crop Science ; THE EFFECT OF MALE STERILITY on grain yield has been investigated since CMS was first used to produce hybrid seed of maize. The published results are contradictory. Rogers and Edwardson (1952) reported a positive CMS effect on the grain yield of single- and double-crosses. Sanford et al. (1965) and

Crop Science ; MODERN CULTIVARS of field-grown crops do not satisfy all the requirements and demands of organic agriculture. Therefore, more attention should be given to breed specific cultivars adapted to the agronomic conditions on organic farms and complying with the philosophy of organic agriculture. Organic
Increase in the Yield of Cytoplasmic Male Sterile Maize Revisited.
Crop Science ; CYTOPLASMIC MALE STERILITY of maize in the 1950s and 1960s received a great deal of attention as an inexpensive means of producing hybrid seeds of high purity. Several investigations concentrated on possible changes in general agronomic performance with special emphasis on yield. These studies were
