Fenugreek ( Trigonella foenum-graecum L.) seeds which introduced from United Arab Emirates were carried to the space by the recoverable satellite "Shi Jian 8". After space loading, the seeds were planted to be observe and investigated compared to the control group. The results showed that the germination rate declined after space loading compared to the control group.

Ear Rows is an important agricultural character in Maize (Zea mays L.).

玉米穗行数是一个重要的农艺性状。

The results showed: 1 RN didn't the leaf width,leaf long,leaf area,yield,productive value and average price of flue-cured tobacco,but had significant effect on grad composing,content of chemical component and the accumulation of N,K and Cl.Within limited rang of RN,the relations between yield,average price,yield of high grad tobacco,yield of low grad tobacco,nicotin,N,reducing sugar,Cl,amylum,volatile base and the quotient of ammonium would been described by significant quadratic polynomial,and the relations between K and the quotient of ammonium conformed to negative linear equation;2With a RN of 75%∶25%,the value of proportion of high and middle grad tobacco,content of nicotin,N,K,uptake of N and K/Cl were the highest,volatile base was lowest.

结果表明：1RN对烤烟的农艺性状、产量、产值、均价等没有明显影响，而对烤烟的等级结构、内在化学成分含量、氮、钾、氯的吸收量有着显著影响，可以用显著的二次多项式模型或直线相关方程描述产值、均价、上等烟产量、下等烟产量等经济性状以及烟碱、总氮、钾、还原糖、氯、淀粉、挥发碱等内在化学成分的含量与铵态氮份额之间的关系；2RN为75%∶25%时，中上等烟比例、烟碱、总氮、钾、钾氯比、氮吸收量最高，挥发碱含量最低。

Many important agronomic traits of soybean are quantitative traits, which are controlled by polygenes. Tagging QTL for these quantitative traits is a very important field in soybean quantitative genetics research.

大豆许多重要农艺性状都是由微效多基因控制的数量性状，对这些数量性状进行QTL定位是大豆数量性状遗传研究领域的一个重要内容。

The genetic behavior of these QTLs were investigated accordingto the performance of backcrosses.

5对以IR24为遗传背景的一套籼型渗入系进行了三地两年的详细考察，初步确认了各渗入系中所携带的渗入片段对抽穗期、株高、穗数、实粒数、总粒数、千粒重、单株重和结实率等性状的影响，并初步定位了11个重要农艺性状和产量性状QTLs，估算了这些QTLs的遗传效应，并在回交和测交中进一步确定了这些QTLs的遗传行为，讨论了渗入系在QTL精细定位与杂种优势机理研究中的应用。

Two tobacco F1 hybrids,F2s,backcrosses B1s and B2s and their parents P1 and P2 were used to estimate the gene effects for 7 agronomic and 4 quality characters.

利用红花大金元×青梗，红花大金元×中烟14号P1、P2、F1、F2、B1、B2 6个世代资料对7个农艺性状和4个品质性状进行了基因效应分析。

In this study, genetic analyses were conducted to determine the genetic basis in an elite resistant inbred line Siyi with complete resistance to maize dwarf mosaic. A new genetic model, two dominant complementary genes conditioning the resistance, were found by Mendelian genetic analysis based on parents, F1, F2 and backcrosses in three successive years' field trails. The two genes were further mapped near the centromere of chromosome 3 and 6, respectively by tightly linked microsatellite markers using 242 plants from F2 generation. The resistance gene on chromosome 3 is 1.0 cM apart from the flanking markers phi053 and umc1527, respectively. Whereas the linkage distance between two flanking markers bnlg1600 and phi075 and resistance gene on chromosome 6 was 1.0 and 4.0 cM, respectively. Genotypic analysis of the plants from testcross and F3 populations supported the new genetic manners.

课题组通过连续三年的抗病鉴定，在国内种质资源中筛选出一份综合农艺性状优良、配合力较高的自交系四一，三年的表型遗传研究和两年的分子标记工作，发现四一中的玉米矮花叶病抗性是由两对显性互补基因控制的，进而利用F2作图群体，把发现的两个基因定位在第三和第六染色体的着丝点附近，并获得了双侧紧密连锁的分子标记连锁图谱，其中第三染色体上的分子标记UMC1527和phi053从抗病基因双侧逼近1 cM，而第六染色体上的分子标记phi075、bnlg1600从抗病基因双侧分别逼近4 cM和1 cM；利用B2群体、F2：3家系、BC3F1群体和带有第三、第六染色体抗病基因以及两个抗病基因的近等基因系，进一步证实了四一中成株期抗性是由两个显性互补基因控制的。
