Identification of Watermelon Seed Purity in Green House

The seed purity is an important index of quality for the watermelon seed.In stead of going to Hainan provence for identification,Since 2004,we cultivate watermelon in green house for those breeds which can be identificated at their ovary period,and then make identification.As a result,we save a large number of manpower and material,and get the result in earlier date.
