杂种的

The hybrids of CY×WP was found to show the highest heterosis ratewith a range of values from 2.28% to 18.20% on the four growth traits of body length,body weight, cephalothorax length and abdominal length, while the hybrids ofCY×HB and WP×CY showed the poor heterosis among the six hybridizationcombinations.

研究结果表明，在生长性状上，CY×WP组合的子一代无论在形态性状(体长、头胸甲长、腹节长)还是体重均较其它组合表现出最大的杂种优势(2.28％～18.20％)，而CY×HB和WP×CY组合子一代的各生长性状表现出杂交劣势。

The heterosis of spike number per plant and grain number of main spike were stable in the intervarietal crosses between years, and so were the grain number of main spike in the crosses of common wheat with club wheat, and were the 1000-grain weight in the crosses of common wheat with spelt wheat.

The second part is about animal breeding, including theory and method on animal breeding, such as selection and assess of breeding, breed method and essentiality of animal breed and animal strain, application of crossbreed and heterosis etc.

二、动物育种：研究动物育种理论和方法，了解种用动物的选择与评定，畜禽品种和品系的培育方法及重要性，杂交育种和杂种优势的应用等。

By determing the photosynthetic production rates in the 46 hybrids and 21 parental inbred lines, the results show that the dominancy of average photosynthetic production rate in F1 is 16.4 %; when the parent of high photosynthetic production rate is used as female parent, the dominancy of the photosynthetic production rate in F1 is over its parent by 8.8 %, otherwise, used as male parent, by 0.9%.

通过对46个杂种及21亲本自交系光合生产率的测定结果表明：F_1平均光合生产率优势为16.4%。用高光合生产率亲本作母本时，F_1光合生产率优势超亲8.8%，反交F_1光合生产率优势超亲0.9%；母本光合生产率遗传力，大于父本光合生产率遗传力11倍。低光合生产率亲本的光合生产率遗传力大于高光合生产率亲本光合生产率的遗传力1.6倍。

Heterosis making use of the male sterile breeding be able to save large amount of emasculation labour,ensuring that seed purity.It is possible that breeding can be solved while the trend of single tea varieties and genetic breeding the problem of insufficient resources.

利用雄性不育育种可以节约大量母本去雄的劳力，保证种子纯度，充分发挥杂种优势，同时可以解决育种中存在的茶树品种趋向单一化和遗传育种资源不足的问题。

Some thought it was part flying squirrel or some other wild animal, which is not impossible, for, according to naturalists,prolific hybrids have been produced by the union of the marten and domestic cat.

有人以为这猫的血统一部分是飞松鼠，或别的什么野兽，因为这并不是不可能的，据博物学家说，貂和家猫支配，可以产生许多这样的杂种。

The results showed that there was a linear regression between F1 heterosis and the genetic differential index of its parents.

结果表明，杂种一代某些性状的优势率与其双亲间的遗传分化指数存在极显著的直线回归关系。

The morphological and anatomical characteristics of"Zha′ai 76"Comparing with the plants of normal M.baccata and ordinary hybrid,"Zha′ai76"and other plants with Dw major gene showed that:the length of springgrowth or main shoot is shorter by 59.6-66.2%;the ratio of length:diame-ter of new shoot smaller by 33.2-58.4%;the length of internee shorter by14.0-42.7%:the node number of spring growth lesser by 40.7%;the cauli-cle height under the cotyledons of hybrid seedlings shorter by 65.0%;the in-dex of leaf stalk(stipe length:stipe thiek ness)on the spring growth smaller by34.5-50.2%;the length of leaf stalk shorter by 25.2-45.7%;the boundarybelt between spring and autumn growth has knob-like nodes;the margin of leafappears wave-like;the sepals with spinous proeessuses are massive and small;the eonstriction at calyx is not obvious;the trace of abscisic sepals is big;the ca-lyx end of fruit is plan or convex;the shape of shoot tip(of"Zha′ai 76")iswider and shorter;and in 1.0mm part from the top of shoot tip,there are manyspecialized cells which are larger in volarae,but with lesser inner material andwith smaller or no nucleus.

"扎矮76"的形态解剖特征与普通山定子和杂交后代中普通型植株对比，"扎矮76"和其它携带Dw主基因植株的：春梢短59.6-66.2％，梢长与梢粗比值小33.2-58.4％，节间短14.0-42.7％，春梢节数少40.7％，杂种苗下胚轴短65.0％，春梢叶柄形指数小34.5-50.2％，叶柄短25.2-45.7％，春秋梢交界处有瘤状突起，叶缘波状，萼片肥厚有刺状突起，萼部缢痕不明显，脱萼后萼痕较大、萼洼平或高于果面；新梢生长点宽而短，在距顶端1.0gmm处有较多体积较大、内容物较少、细胞核小或无的待化细胞。
