And it also showed that the inheritance of the growth-rate and pathogenicity to cotton seedlings of XC-6 could not be inherited steadily in zoospore progenies and oospore progeny, but the colony morphology and homothallic character of XC-6 could inherited steadily in both asexual and sexual progenies, which suggested that the inheritance and variation of the above characters might be related to long-selfing and hybridization in species.

同时，XC-6生长速率、对棉苗的致病力、菌落形态及同宗配合遗传和变异特性研究表明，其生长速率和对棉苗的致病力性状在单游动孢子后代和自交后代均不能稳定遗传，但菌落形态和同宗配合特性在单游动孢子后代和自交后代均能稳定遗传，提示上述性状在单游动孢子后代和自交后代的遗传和变异特性可能与菌株长期自交和种内杂交有关。

Based on the obvious xenia effects of high oil and heterosis, a technique called TEU(three-effect-utilization) was developed to pyramid the cytoplasm male sterile effect, heterosis and xenia of oil content into a production system, which has patented in China.

从20世纪20年代开始，玉米杂种优势利用经历了综合种、双交种、三交种、单交种阶段，每一次利用方式的改变都使玉米生产的水平得到了很大的提高。

Three full-sibling binary CMS lines, 11 back-cross binary CMS lines, 10 half-sibling binary CMS lines, 10 isozygoty CMS lines and five restorer lines were chosen to make 50 single hybrids and 120 modified single cross hybrids by the way of NC Ⅱ design. The plots of F1 were arranged in the field in a randomized complete block design with 2 replications and the combining ability of 7 characters were analyzed using random model.

利用3个全同胞型二元不育系、11个回交型二元不育系和10个半同胞型二元不育系及其10个亲本纯合不育系，分别与南恢04、明恢86、辐恢838、先恢207和密阳46等5个恢复系按照NCⅡ交配设计配制了50个单交种和120个改良单交种，按随机区组的随机模型分析方法，对二元不育系主要性状进行了配合力分析。

Formula for prediction of general heterosis and interaction heterosis of single-cross offspring based on QTL effects were deduced.

In maize (Zea mays L.) single-cross breeding programs,identifying high yielding hybrids and inbred lines with superior performance is an important problem.

在玉米单交种育种中，鉴定高产杂交种和具有优良特性的自交系是一个重要的问题。

To estimate the quantitative genetic parameters of nitrogen use efficiency, twenty maize single-cross hybrids with varying nitrogen use efficiency were tested at two locations in the North China Plain. At both locations, the hybrids were grown under high (HN, 225 kg/hm^2 N) and low N levels. And no N fertilization on the LN field have lasted two years.

为研究玉米品种氮利用效率相关性状的遗传参数，本试验选择20个具不同氮利用效率的单交种在华北平原的2个地点同期进行试验，氮肥处理设高氮（施氮，折合纯氮225 kg/hm^2）和低氮（不施氮，其地块经过连续2年耕种使氮素耗竭）2个水平。

A software for QTL mapping—QTLMapper 2. 0 written by C/C++ language was developed. The sotftware could analyze populations of DH, RIL, F〓 and permanent F〓, and could provide unbiased estimation for all genetic main effects and/or unbiased prediction for all QE interaction effects. The software could also predict heteroses of single-cross offspring based on QTL genetic main effects and/or QE interaction effects obtained in QTL analysis of F〓 or permanent F〓 population.

用C／C++语言编写了适于分析DH群体、RIL群体、F〓群体和永久F〓群体的QTL作图软件QTLMapper 2.0，能够提供对各项遗传主效应的无偏估计和／或对QE互作效应的无偏预测，还能基于F〓群体或永久F〓群体估计的QTL遗传主效应和／或QE互作效应预测单交后代杂种优势。
