In order to produce a good F1 hybrid variety in wheat, it is necessary to explore a new male-sterile cytoplasm and its nuclear restore gene. Four alloplasmic male sterile lines of wheat with Aegilops cytoplasm were developed to identify mitochondrial DNA variation that could potentially be associated with cytoplasmic male sterility.

Embedding the gradient direction search and new kinds of evaluation functions into the Genetic Algorithm, a special hybrid Genetic Algorithm with mutation along the weighted gradient direction to solve non-linear programming problems is developed. Then in Chapt 4, a type of nonlinear programming problems with fuzzy objective and fuzzy resources constraints is discussed, in which the objective is ill-defined and the resources possess two different types of fuzzy resources, i. e., tolerance and imprecision. By way of description and formulation of fuzzy objective and fuzzy resources, the problem with fuzzy objective and two different types of fuzzy resources is modelled into a fuzzy nonlinear programming model FO/RNLP and interpreted as three equivalent alternative crisp model to reflect the variety of the environment and the subjective and preference of the decision maker .
