The new plant type Indica and Japonica varieties showed somewhat check heterosis whencrossed with one of the four sterile lines. America Japonica varieties showed few fillers andlower seed set ratio and Africa Japonica varieties, Nuda varieties, Javanica varieties have fewtillers and taller plant height, so they could not be used directly in Japonica hybrid ricebreeding program.

美国稻的分蘖少且结实率较低，产量优势不大；非洲稻的分蘖少，实粒数也少，株高太高，无法直接利用；新株型粳稻与培矮64s、N422s配组有一定的优势，新株型籼稻与N422s、108s配组的优势也较大，在华北两系杂交粳稻育种中也有一定的利用价值；光壳稻和爪哇稻的株高偏高，无法直接利用，可间接利用这两个生态型千粒重大的特点。

Through the tests on gas driving water and water driving gas, the flow law of gas and water was real-time observed. Mainly based on the test of water driving gas as an example, the development of molding coal sample and NMR triaxial osmoscope was demonstrated. The experiment process of water driving gas and parameters were demonstrated. NMRI images of molding sample in horizontal cross-section along the driving direction were obtained by NMRI instrument. The results from images were analyzed and compared. Some novel laws were obtained as the following:(1) the leading edge of water driving has inconsistency. This certified the important previous conclusion that the storage of methane mainly was absorbed in inner surface of pore from NMRI technique;(2) the existence of dominant driving pathway was tested and the way kept almost fixed. The pathway is apt to exist in the edge of coal samples where pore and fracture fully develop;(3) the variation of water flow determines the transport velocity of leading edge of water driving and it has lag effect;(4) the effectiveness of the first driving is better than the second driving;and (5) the subsequence of water driving gas are from trunk fractures to branch fractures, then to branch pores.

主要以水驱气NMRI试验为例，详细介绍了核磁共振三轴渗透仪和型煤试件的研制，并重点阐述了水驱气试验过程和相关参数，利用NMRI技术实时观测得到了不同时间沿驱替方向型煤试件水平剖面的NMRI成像图，最后对试验结果进行了比较分析，揭示了一些新的规律认识：(1)水驱替前缘具有不一致性，从NMRI试验角度验证了前人甲烷类气体赋存形式主要以吸附在孔隙内表面为主的重要结论；(2)煤试件存在优势驱替路径，且这种优势路径在驱替过程中基本保持不变，水驱气的优势驱替路径易产生在煤试件边缘，即煤孔隙裂隙发育区；(3)水驱流量变化决定了水驱前缘的运移速度，且对水驱气效果具有滞后效应；(4)水驱气初次驱替效果好于二次驱替效果；(5)水驱替气的顺序为：主要大裂隙—周边裂隙—周边孔隙。

Stuber et al.(1992) considered the overdominance is the major genetic basis of heterosis in maize; Xiao et al.(1995) suggested the dominance is the major molecular mechanism of heterosis in rice. Subsequently, Yu et al.(1997) and Hua et al.(2003) demonstrated the epistasis made the siginificant contribution to heterosis in rice.
