    Since the discovery of Tomato spotted wilt virus(TSWV) in the 19th century,it has spread
    all over the world,causing great economic losses to various crops.Taking pepper as an example,this
    paper reviewed the research status on TSWV in pepper at home and abroad from 6 aspects:occurrence and
    distribution of TSWV disease,detection of disease symptoms,transmission mode,control methods,TSWV
    resistant breeding and prospects for TSWV.

    Anthocyanins are water-soluble pigment belonging to flavonoids compounds,and having
    multiple biological functions,including protecting plant from UV damage,eliminating reactive oxygen
    species,resisting stress and changing plant color and lustre,etc.At the same time,they have health
    efficacy as anti-aging,preventing obesity and cardiovascular diseases,etc.A few lettuce varieties are
    purple in phenotype,rich in anthocyanins.This paper described the biosynthesis and regulatory pathway
    of anthocyanins in lettuce,and factors affecting anthocyanins accumulation in lettuce,aiming at providing
    referrence information for developing lettuce functional foods rich in anthocyanins contents.

    In order to clarify the effect of mapk two-stranded RNA expression carrier transgenic cucumber
    on soil nematode diversity,this paper adopted 18S rDNA gene cloning library method and studied mapk twostranded
    RNA expression carrier cucumber and diversity of soil nematode in rhizosphere of non-transgenic
    cucumber. The results showed that the soil nematodes in rhizosphere of transgenic cucumber and non-transgenic
    cucumber were mainly bacterial-feeding nematode including Rhabditis sp.,Cephalobus sp. and Acrobeloides
    sp. There was no significant difference in diversity index and ecological index,indicating that there was no
    significant influence of mapk double-stranded RNA expression carrier cucumber on soil nematode diversity. It
    has higher biosecurity.

    Changes of tomato fruit firmness at different development stages were compared between hard
    type accession‘ TS330’ and soft type accession‘ A57’.The results showed that the fruit firmness of‘ TS330’
    was significantly higher than that of ‘A57’ at mature green stage,breaker stage and red ripening stage,of
    which there were maximum differences during mature green stage.The cell wall thickness,cell density(cell
    layers per unit thickness)and pectin content of ‘TS330’ fruit at mature green stage were significantly higher
    than those of ‘A57’ fruit.The fruit firmness of ‘TS330’,F1(‘TS330’בA57’)and ‘A57’ at mature
    green stage were 26.86,21.09 kg · cm-2 and 19.11 kg · cm-2,respectively.The tomato fruit firmness was
    closely related to its cell density( correlation coefficient 0.96) and pectin content( correlation coefficient 0.99).
    The fruit firmness of‘ TS330’בA57’ F2 population tended to a normal distribution,indicating that tomato
    fruit firmness was controlled by multiple loci.

    This paper studied the effects of nutrient solution pH and salt interaction stress on ginger yield
    and quality by quadratic saturation D-optimization design,and established dyadic and square mathematical
    models with pH and salt dosage as variable factors and ginger yield and quality as objective function.The
    model analysis indicated that pH and salt content had significant interaction effect on ginger yield and quality.
    Salt content was the dominant factor for yield;pH was the dominant factor for quality.Low level pH change
    had no significant effect on ginger yield.When pH rised to 7.70,the ginger yield showed a rapid downtrend
    along with the rise of pH.While along with the increase of salt content,ginger yield continued to decrease.
    Along with the rise of pH,ginger quality showed a slow decrease tendency.When salt content was lower than
    77.91 mmol · L-1,the ginger quality went up along with the increase of salt content,later the ginger quality
    went down along with the increase of salt content.

    In order to evaluate the reliability of cold tolerance identification indicators and analytical
    methods for different potato germplasm resources,and to screen different cold-tolerant potato materials,
    this study used conductivity method and field natural frost method to identify and analyze the cold tolerance of
    103 potato germplasm resources by membership function method and clustering analysis method.The results
    showed that the semi-lethal temperature and frost phenotypic classification combined with membership function
    method and clustering analysis method could effectively evaluate the cold tolerance of potato.Taking the above
    comprehensive evaluation method,21 parts of non-cold resistant materials,and 16 parts of cold resistant
    materials were obtained.Thus,certain references for directional collection of cold-tolerant potato resources
    were provided.

    Taking 98 accessions of welsh onion as test material,this paper analyzed their diversities
    in 16 phenotypic traits.The results indicated that the genetic diversity of welsh onion germplasm resources
    were rich.The quantity traits and quality traits of those with the highest diversity index were the tightness
    between plant height and leaf node,respectively.Those with the biggest variable coefficient were single plant
    weight.The paper also conducted clustering analysis on welsh onion germplasm and divided them into 4
    groups.The germplasm of group I were mostly‘drawf and thin’straight type onion.The germplasm of
    groupⅡwere chicken leg type with short cauloid.The germplasm of group Ⅲ were mainly of‘tall and
    thin’straight type onion with loosen and bigger space between leaf holes.The germplasm of group Ⅳ were
    mainly of‘tall and thick’straight type with many wax powder and leaves.

    Adopting indoor inhibitory on bacteriostatic activity and soaking seed potting experiment,
    this paper investigated the control effect of Novonestmycin A on Rhizoctonia solani damping-off of watermelon.
    Results of laboratory test indicated that Novonestmycin A had strong inhibitory effect on bacteriostatic activity
    of Rhizoctonia solani,and its median inhibitory concentration was 1.726 0 μg · mL-1. After being treated
    with Novonestmycin A of 10 μg · mL-1 concentration,the hyphae became morphologically irregular under
    observation of optical microscope and scanning electron microscope. The results of pot experiment showed that
    the control effect of soaking seed at the concentration of 4 000 μg · mL-1 Novonestmycin on Rhizoctonia solani
    damping-off of watermelon was 91.83%.

    Taking questionnaire method in every household of a village,this paper investigated in detail
    the present status of production and fertilization on seed lotus in 6 towns of Guangchang County,Jiangxi
    Province.Results showed that under present production and management conditions,the average yield of seed

    lotus was 1 074 kg · hm-2.The differences in yielding level of different towns were mainly related to planting
    pattern and variety,while planting pattern had a bigger impact than the variety.At present,the average yields
    of extensively extented‘ Taikonglian No.36’and‘Jianxuan No.17’were 1 188 kg · hm-2 and 1 007 kg · hm-2
    respectively,less than 85% of their yield potential.Disease and pest,successive cropping obstacle,irrational
    fertilization,bad weather,variety degeneration and source of water were the important factors for low yield.
    Aiming at the major existing problems in fertilization,technical counter measures were put forward:to use
    organic fertilizer,to rationally regulate the rate of nitrogen(N),phosphorus(P)and potassium(K),to
    apply alkaline fertilizer,to supplement medium,trace and beneficial element fertilizers,such as calcium,
    magnesium,borax,etc.,to rationally conduct fertilizing time and method.
