Directed on the present situation and existing problems in boosting beef cattle industry based on the yellow cattle improvement in china, the review indicated that several relationships, such as integration of individual households and large scale cattle farms, integration of yellow cattle improvement, crossbreeding, breed conservation and utilization, integration of high grain diet intensified fattening and low grain diet economic fattening, should be handled properly ; and the requirements of profitable cattle industry for increasing reproductive survive rate, using hybrid vigor and improving the weight gain, the main factors affecting economic return of large scale cattle farms and the technology level improvement in cattle industry were duiscussed as well
本文就近來我國以黃牛改良為特點的肉牛業蓬勃發展現狀與存在問題，指出應處理好養牛經營形式千家萬戶與規模牛場相結合、黃牛肉用與肉役兼用相結合、黃牛改良選育與雜交、保種及利用相結合、高精料強度肥育與低精料適度育肥相結合等幾個問題；並就提高養牛經濟效益對提高繁殖成活率、充分利用雜種優勢、提高日增重的要求和影響規模牛場經濟效益的主要因素及如何提高養牛科技水平等問題提出探討。 -
The results show that the genetic diversity of filial generations is higher than self - bred progeny ’ s ， the hybrid vigor has manifested at metabolization level 。 the proportion of polymorphic loci ( p. 99 ) in f1 generations was 30. 77 - 36. 36 % ， the mean observed heterozygosity ( ho ) of jmcf （ japanese male chinese female ） was the highest with 0. 1727, the rest populations were ： jfcm （ japanese female chinese male ） 0. 1536 、 cp 0. 1273 and jp 0. 1055 ， the mean effective number of allels per locus in f1 generations ： cp ’ s was the highest with 1. 7318 ， jp ’ s was the lowest with 1. 6718 ， the filial generations ’ values were in the midle of the cp ’ s and jp ’ s and between them there was no brightly difference, with 1. 6955 ( jfp ) and 1. 6927 ( jmp )
各組的平均雜合度預期值也表現出該趨勢，即：日自交組最低，為0 . 1786 ，日雄中雌雜交組的平均雜合度最高，為0 . 1964 ，日雌中雄雜交組和中自交組分別是0 . 1891和0 . 1865 。 hardy - weinberg平衡下遺傳偏離指數也是雜交組的小於自交組的，平均每個位點的等位基因有效數目中自交組最高為1 . 7318 ，日自交組最低為1 . 6718 ，兩雜交組群體的這一指數相差不多，分別是1 . 6955和1 . 6927 ，位於兩親本的中間水平。 -
The properties of the hybrid, such as greater vigor and adaptability, are retained in the allopolyploid in subsequent generations and such organisms are often highly successful
這種具有高度生活力和適應性的雜交在異源多倍體中被保留，而且可以成功的遺傳下去。 -
If you should be privileged to see a commercial bench of a candidate hybrid in bloom, you can learn more in half an hour about dominant and recessive characteristics, plant size and health, growth habit and vigor than you could in a year of attending orchid shows
如果你有機會看到商業展臺上的開花的候選雜交種，你就可以在半個小時里就學到很多關于顯性和隱性性狀、植株大小與健康、生長習性和活力的知識，比你在一年中參觀蘭展學到的還多。
