Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。

It includes the following steps: extract trivalent iron ion and divalent iron ion in water phase through organic extractant, get predecessor of; absterge it with secondary distilled water for2-3 times and get pure load metal predecessor of organic phase; mix organic phase of Mg2 and Fe3 with mol rate of 1:2 and introduce them into autoclave, add distilled water according to the rate of 3:1 or 4:1 of organic phase and water phase and airproof it, and then mix it fiercely, stripping with hydrothermal method at temperature between 200 degree C and 300 degree C and make them react for 2.5 hours; cool it to the room temperature under natural condition, separate liquid and centrifugalize it, absterge it with absolute alcohol for 2-3 times and dry it at temperature of 50 degree C for 30-180 minutes, then get product of magnesium ferrite.

包括如下步骤：通过有机萃取剂来萃取水相中的三价铁离子和二价镁离子，制得有机相前驱物；用二次蒸馏水洗涤2-3次，获得纯净的负载金属有机相前驱物；按照Mg 2 和Fe 3 摩尔比1∶2将有机相混合均匀后引入高压釜中，按照有机相与水相的比例为3∶1或4∶1加入蒸馏水，密封后，对溶液进行强力搅拌，水热反萃的温度在200-300℃之间反应2.5小时；自然冷却至室温，分液，离心分离，用无水乙醇洗涤2-3次，在50℃下干燥30-180分钟，得铁酸镁产品。

Potassium salt of dicyclopentadienyl dicarboxylate DCPD(COOK2 was applied to CPE as crosslinking agent and a crosslinked product with 81.79% gel content was obtained in solution reaction.
