This study analyzed the genetic diversity of green foxtail, yellow foxtailand foxtail millet disturbed in the North of china using twelve allozyme (21 loci),such as AATS ADHS AMPS DIAS GDH.. IDHS MDHS ME~ PGD, PGI5 PGMS SKD. The test of gene flow between cultivated population of foxtail millet and its wild relative, green foxtail, was carried out in the field, using a dominant sethoxydim resistant line as a pollen donor and a population of green foxtail as a recipient.

本研究以我国北方近缘种青狗尾草为材料通过对12种等位酶（AAT、ADH、AMP、DIA、GDH、IDH、MDH、ME、PGD、PGI、PGM、SKD）共21个位点的分析研究它们的遗传多样性；以显性抗除草剂谷子种质作为花粉供体材料，以不抗除草剂青狗尾草作为花粉受体材料进行了栽培种向其主要近缘野生种基因漂移的检测研究。

The results of research could supply some information for establishing estimate indexes of salt tolerance of plants in order to filtrating resources of halophytes of Xinjiang and empoldering saline soil.

The resistances to maize head smut of some lines from maize semi-exotic populations containing CIMMYT germplasm and local lines were identified by the method of artificial inoculation under field condition.

董玲1，2，王庆祥1，金益2，于天江2，罗娜2，高明波2，刘红军21沈阳农业大学农学院，沈阳110161；2东北农业大学农学院，哈尔滨150030本文采用田间人工接种方法研究了部分含CIMMYT玉米种质的半外来群体选系对丝黑穗病的抗性。

Using logistic model, regression equations were established as followed: y=12.084 8/［1+exp (6.372 5-0.367 5x)］ and y=91.017 0/［1+exp （18.448 8-0.788 8x）］, which was used to evaluate the responses of maize inbred lines to head smut resistance.

采用逻辑斯蒂模型分别建立了抗、感自交系可溶性糖含量与田间发病率的一元曲线回归方程：y=12.084 8/［1+exp (6.372 5-0.367 5x)］和y=91.017 0/［1+exp（18.448 8-0.788 8x）］，以此建立了以接菌幼苗可溶性糖含量为指标的抗性评价方法，并用于未知抗性种质资源的鉴定。

Some important issues, such as the identification of synonyms and homonyms, the classification of germplasm resources, the breeding with sexual cross and early selection, the discovery and evaluation of mutants, and even the localization and cloning of important genes are all important research subjects to be addressed.

例如，荔枝品种中同物异名与同名异物情况的区分、种质资源的鉴别与合理的分类、杂交育种与早期选择、突变的发掘与鉴定评价、甚至重要性状基因的定位与克隆等，都是很需要解决的研究问题。
