Papaya ringspot virus (PRSV) is a fungal disease that causes is important to pumpkins. The use of varieties of resistance, it is recommended that the guidelines for managing to find the sources of genetic resistance of sheep infection PRSV. collect 8 varieties of pumpkin varieties come evaluate the level of bacterial resistance in crops grown in greenhouses, test mechanical way, fuel is charged with planting the PRSV, fuel.ก่ต้นกล้า pumpkin varieties, there are 30 pumpkin varieties and weak resistance and infection control are 15 species of PRSV. 4 weeks after planting, do not collect the fuel comes to detect Indirect ELISA method with Pythium PRSV then calculated as a percentage of the disease by means of networks and the Board (2536 (1993)) and statistical calculation, the Duncan from the assessment found there are 5 varieties of pumpkin varieties is resistance and resistance is 102 103 AV-PK-P103, AV-PK-P106 AV-PK-P102, 106, 107 AV-PK-P107. Lae-108 AV-PK-P108 With weak species per 100% infection is LL-112 disease and bacterial resistance varieties are not 100% AV-NL-113 is a species of the controls which will be carried out to test the resistance traits in a converted the next trial.
