Abstract: The development of strategies to improve crop plants by the production of hybrid varieties is a major goal in plant breeding. Hybrid progeny often have a higher yield, increased
resistance to disease, and enhanced performance in the different environment compared with the parental lines. Availability of cost effective mechanism/ method to produce
large scale hybrid seed utilizing selected parental line is one of the important factors which ultimately determine the commercial viability of hybrid varieties. Manual
emasculation increased the cost of production, so the use of various genetic mechanism via; male sterility, self-incompatible, gynoecious lines, use of sex regulators and chemical
hybridizing agents based on relative importance in hybrid development. Among these, genetic emasculation tools male sterility is commonly used for hybrid production. Male-sterile transgenic plants can be obtained through a genetic transformation with related genes destroying or interfering with pollen or anther development. Male sterile
cauliflower, tomato, cabbage, etc. have been developed in this way, and some begin to be used to produce hybrid seed. Appling some techniques can also maintain and restore
the male sterility. These related researches will effectively promote the heterosis utilization and the development of crop breeding
Summary: Male sterility Increase flower longevity and number.
 Eliminate nuisance fruit.
 Increase vegetative growth.
 Reduce allergic reactions.
 Prevent sexual propagation and crossing.
 Eliminate invasiveness.
 It’s a new tool to eliminate plant invasiveness.
