GISH analysis showed Triticale have 2 items chromosomes presented yellow and others chromosomes presented chrysoidine, because yellow chromosomes combined the Thinopyrum intermedium DNA, others chromosomes dye by PI. 4. Analysis of resistance gene: CH-9916 is the hybrid progenies of Octoploid tritielytrigia TAI-7045 X common wheat "Jinmai33".

GISH分析结果表明，小偃麦衍生系CH-9916的42条染色体中有2条外源染色体因结合有探针DNA而呈现出较强的黄色杂交信号，而没有结合上探针DNA的普通小麦染色体经过PI染色呈现出桔红色，初步推断小偃麦衍生系CH-9916为一个&小麦一中间偃麦草&的代换系。

The Argentine newspaper Clarin reported the country's government is considering a plan to increase the export tax on soybeans and lower the export tax for corn and wheat in an attempt to boost corn and wheat production.

阿根廷报纸《Clarin》报道说，为促进玉米和小麦产量，政府正在考虑上调大豆出口税、下调玉米和小麦出口税的计划。

Changes of DBE activity of four cultivars had a single-peak curve, and the peak appeared in 14 d after anthesis. HPLC analysis showed that the activity of DBE to amylopectin was similar. There are two types of DBE in the wheat grains, one is isoamylase, and the other is limit dextrinase.

在灌浆过程中，淀粉去分支酶的活性均呈单峰曲线变化，灌浆中期活性最大；淀粉去分支酶对底物支链淀粉均具有相似的酶解活性；对灌浆中期小麦淀粉去分支酶进行的纯化结果表明，小麦籽粒胚乳中也存在2种类型的淀粉去分支酶，一种是以极限糊精为特异性底物的极限糊精酶，另一种是以支链淀粉为底物的异淀粉酶。

Based on F1 diallel crosses involving eight genetically diverse wheat cultivars, inheritance of harvest index and its correlations with agronomic traits were analyzed.

利用8个不同收获指数小麦品种双列杂交的F1及其亲本，探讨小麦收获指数的遗传及其与主要农艺性状的相关。

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。
