  2. This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits

    本研究利用12個普通小麥品種對10個種子活力性狀的遺傳變異和相關研究，表明除正常幼苗百分率外，其餘種子活力性狀在品種間均存在顯著的差異.種子貯藏物質轉換效率、電導率兩個性狀間及與其它性狀均無顯著的遺傳相關，因此對他們的選擇不會影響到其它性狀.通徑分析表明幼苗干重主要取決于種子貯藏物質轉換效率、種子貯藏物質利用速率;發芽指數主要由平均發芽時間決定.電導率、發芽勢、幼苗干重、種子干重、發芽指數、種子貯藏物質消耗比率6個性狀表現中到高的遺傳力、遺傳變異系數和相對遺傳進展，指明通過遺傳育種手段改良這些性狀是可能的
  3. In the artificial - planting, the strain of cordyceps militaris is easy to degenerate. at present, the study about the fungus in cordyceps genus are just in the identification of fungi 、 the nutrition analysis 、 the using in medicine and artificial - planting. although, it could reduce the lost by the usual breeding way, we could not solve the problem at basic. about the degeneration of strain, people mostly use the gender - cycling 、 the fusing - cytoplasmic technology and the genetic - engineering method to reform the strain. most of people use moleculor method in the study of relationships among the species and between the species

    用常規選育方法雖然能減少一定的損失，但不能從根本上解決菌種退化這一長期困擾企業生產的問題。針對菌種退化問題，主要是利用有性循環、原生質體融合和遺傳工程等途徑進行菌株改良，應用分子生物學手段只是研究種內、種間的系統關系等，而關于菌種退化遺傳機理的研究尚未見報道。菌種退化是菌類栽培過程中普遍存在的，也是生產當中迫切希望得到解決的問題。
  4. Abstract : robertsonian translocation is important in the study of evolution biology. current progress, contents, technology and methods about robertsonian translocation studies are introduced in the article. the usefulness in improving the breeds of pasturages and molecular genetic aspect are also discussed

    摘要本文總結了羅伯遜易位研究的現狀、內容和技術方法，並對它在畜牧品種的改良、分子遺傳學方面的應用作了探討，指出了它在研究進化生物學方面的重要意義。
  5. Abstract : techniques of apple genetic transformation can improve apple trees and shorten the breeding cycle by molecular methods. in the last years, great progress has been made in this field, which involves a number of important apple genotypes developed. so far, apple genetic ransformation mainly adopts agrobacterium - mediated technique, involving infection and transgenic tissue regeneration, which are important steps to affect the transformation efficiency. the initial work to the date is to know and to search for the factors which can increase the efficiency

    摘要蘋果的遺傳轉化技術通過分子手段改良蘋果，有助於縮短其育種周期.最近十年，在該領域的研究取得很大進展，涉及到一些重要的蘋果基因型及有用的外源基因.迄今，蘋果的遺傳轉化主要採用農桿菌介導法，侵染與轉化材料的再生是影響其轉化效率的關鍵過程，了解其影響因素，尋找有利因素以提高轉化效率是目前蘋果遺傳轉化研究的重點。
