以宁 6 7A等 4个粳型不育系与 K172 2等 9个粳型恢复系进行不完全双列杂交，采用禾谷类作物胚乳品质性状的遗传模型及其分析方法，对粳型杂交稻稻米外观品质性状进行了遗传研究。

One is a large scale nonlinear programming model with equalities, the other is a more complicated NP hard and nonlinear compound 0-1 programming model. It is difficult for the existed algorithms to fulfill the demands of efficiency and size for the above problems. Two corresponding genetic algorithms are presented, in which several suitable genetic operations are constructed to make the optimization search process in the range of feasible solutions.
