First of all, game theory methodology will be introduced into the selection of underlying index, and we try to explain why hedgers and arbitragers are crucial to the index futures market in China.

Therefore, stem diameter and leaf number could be considered as two principal selection indexs for breeding new varieties, evaluating yield and select.

Based on the investigation,the article focuses on the exploration of the relationship between the index and process,suggests the related indexes that are primarily assessed during the different selection phases,and constructs the supplier selection model of the relationship between the supplier selection index and selection process in multinational companies\' purchase in China.

These include theoretical researches and applications of marker-assisted backcrossing, index selection, and best linear unbiased prediction (BLUP) in animal and plant breeding.
