Abstract Male and Female sterilization are permanent methods of contraception. While female sterilization is far more common than male sterilization, vasectomy is safer, simpler, about half the cost of female sterilization, and is more effective. Female sterilization, in the form of laparoscopic sterilization is the more common procedure being done ...

Engineered Male Sterility [PDF]
, 2009 The agricultural exploitation of hybrid crop varieties has enabled enormous increases in food productivity through increased uniformity and hybrid vigour. Because of hybrid vigour, or heterosis , these crops are characterized by an increased resistance to disease and enhanced performance in different environments when comparing the heterozygous hybrid ...

Cytoplasmic Male Sterility [PDF]
, 1983 The trait cytoplasmic male sterility (cms) is common in higher plants. Edwardson (1) reported that the cms trait had been observed in at least eighty unique plant species. Although the trait may manifest itself in different fashions among the various species, cms plants have in common the inability to produce viable pollen.

In view of the definition of male sterility given earlier, a tentative scheme of classifying different types of naturally occurring malesteriles may be based primarily on two criteria, namely the phenotypic identity and the cause of incidence.

Recently the topic of male sterility in plants was reviewed by Frankel and Galun (1977). In the present Chapter, the work on male sterility in Petunia will be discussed. Male sterility in Petunia is expressed as the lack of pollen grains in the anthers of otherwise normal flowers.

, 1988 Utilisation of mst permits hybrid seed production and commercial exploitation of heterosis in crops where emasculation on a large scale is not possible. The occurrence of commercially utilisable g-mst or gc-mst is, however, uncommon in economically useful plants.

Genic Male Sterility (g-mst) is of a wide occurrence in flowering plants and the majority of the steriles have arisen as spontaneous mutants (Table 2.1). Only a few have been induced after mutagen treatments (Table 2.3). In about 175 species in which mst has spontaneously arisen, the majority are dicots in species as well as in species crosses (Fig.
