The invention discloses a method for grafting melons on double rootstocks, comprising the following steps: (1) simultaneously sowing the rootstocks cucurbita moschata and cucurbita ficifolia in pairs; (2) sowing the seeds of the melons 5-8 days after sowing the rootstocks; (3) when the diameter of the first mainleaf of the rootstock cucurbita moschata is 4.5-6cm, removing the first mainleaf of the cucurbita moschata, removing the growing point of the cucurbita ficifolia and grafting the rootstocks by inarching, and meanwhile, bevelling the parts of the lower hypocotyl, 1.5-2.5cm from the cotyledon, of the seedlings of the melons and obliquely inserting the bevelled scions of the melons on the parts of the lower hypocotyl, 0.3-0.7cm from the cotyledon, of the cucurbita moschata by the grafting needles; and (4) managing the seedlings and planting the seedlings 2-4 days later. The method realizes simultaneous inarching of the two rootstocks and cuttage grafting of the scions of the melons and the rootstocks, greatly improves the operation efficiency, greatly lowers the consequent management cost and is very applicable to industrial production of the seedlings raised by grafting.

The invention discloses primers and a method for purity identification of hybrid seeds of Chinese pumpkin 'Guangmi NO.1'. The primers are VRISSRPMK8-F:5'-TAATTAAGGCGTGAAATTGG-3' and VRISSRPMK8-R:5'-GAAAAGAAACATAAACAGGGC-3'. The identification method is as follows: 1) extracting a genome DNA (deoxyribonucleic acid) of a pumpkin seedling; 2) carrying out PCR (polymerase chain reaction) amplification by taking the genome DNA of the pumpkin as a template and using the SSR primers VRISSRPMK8; 3) carrying out gel electrophoresis on the amplified product; and 4) analyzing the electrophoresis result, wherein only the single plant simultaneously having parent specific bands is a real hybrid, and the plant lacking of any one band is marked as false hybrid. The primers and the method can be used for effectively distinguishing the hybrid seed of the 'Guangmi NO.1' from the female parent and the male parent, and can identify the purity of the hybrid seeds rapidly and accurately. The method has the advantages of being fast and accurate, low in cost and simple in operation, and the like.
