In Japonica heterosis utilization, the purity of hybrid seeds was sometimes low due to the self-fertility and/or unstable sterility of some BT type Japonica cytoplasmic male sterile lines. For the WA type Japonica CMS lines, their sterility is much stable, but there is also some difficult to take use of them because their flowering habit is bad and it is very difficult to restore their fertility. The HL type CMS lines were identified to have the same flowering habit and outcrossing rate with the BT type CMS lines in Japonica hybrid rice. Moreover, the sterility of HL type CMS lines was more stable than that of BT type, and their restorable characteristics was better than that of WA type.

部分BT型粳稻不育系存在自交结实现象，不育性的稳定性较差，影响杂交种的纯度；WA型粳稻不育系虽然不育性稳定，但开花习性差，育性最难恢复，应用难度较大；HL粳稻不育系开花习性及异交结实率与BT型粳稻不育系无显著差异，育性稳定性明显好于BT型粳稻不育系，可恢复性明显好于WA型粳稻不育系，较好地协调了育性稳定性、开花习性和可恢复性几方面的矛盾。

In Xinxiang Aera of Henan Province in 1997, the occurrence of cotton pests were investigated in the Bt cotton and common cotton fields The result showed that the numbers of cotton bollworm egg were similarly in both fields, but that of survival larvae on Bt cotton were lower than that on common cotton The occurrence of cotton aphis was no difference but the spider mite were more heavy in Bt cotton field At the same time,control strategy against cotton pests were discussed for the Bt cotton

对河南新乡棉区种植的转Bt基因棉和常规棉棉田虫情进行了定点系统调查和大田普查，结果表明：棉铃虫在两种棉田棉花上的落卵量无明显差别，而幼虫存量差异显著，Bt棉棉花上幼虫存量显著降低；Bt棉对棉蚜的发生无明显的影响，而Bt棉上棉红蜘蛛的发生比常规棉略重，同时初步研究制定出种植Bt棉后的棉虫综防对策

This thesis dedicated to research the investment control of BT project, researched the risk in the program construction, the compose portion and the factors effecting the investment. The research includes the conception and the character of the BT project; the actualize process and the questions should be pay attention to; the conditions of BT contract and the sector of the compose poison of the contract price. In this part researched the conception of the BT purchase price and concluded that the relation between the purchase price and the investment. Then studied the risk factors that effect the investment according to the character of the project and then brought forward several advices of the contract item about how to share the risk. Studied compose sector and it's calculatingly methods of the construction cost which is the main part of the investment, then studied how to control the cost during the construct process and analyzed project variations as well as how control that. In the end, researched the capital cost of BT program, the main content include the concept of the capital cost, the calculatingly methods using the engineering economic method, the method writer suggest in the thesis according to the project practice, how to control the capital cost, mainly through setting up an account and inspecting it, and regulating the program financing rate in reason.
