In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

为了进一步提高其对白叶枯病的抗性、同时增加其对水稻鳞翅目害虫（如稻纵卷叶螟、二化螟和三化螟等）抗性，利用常规回交育种方法和结合分子标记辅助选择将Xa21基因和Bt基因同时导入93-11中，在BC3F3家系中筛选到8个家系含纯合的Xa21基因和Bt基因，其中有两个家系与93-11比较其遗传背景的回复率很高，达到90.59%。

In addressing the heterogeneity factor, this paper will use Logistic regression, the Beta-binomial model the Williams method arid GLMM to analyze the secondary data collected at the incidence of Downy mildew on grapes and Phomopsis leaf blight on strawberrys. Also, there will he a thorough discussion on the advantages and disadvantages among the different model approaches according to -2 Res Log Likelihood, AIC, BIC and residual plots.

本研究旨在探讨病害发生率的研究中，以层次取样法进行抽样，并以实际资料葡萄露菌病和草莓叶枯病的病害发生率为例，藉由计算离势参数、-2 Res Log Likelihood、AIC、BIC和绘制残差图，比较逻辑斯回归、贝他－二项模式、威廉斯模式与广义线性混合模式四种模式对资料进行配适情形，来探讨这些方法克服过度离势的能力并比较其优劣。
