| Cucurbita L is one of pumpkin crops cultivated varieties. It is the richest changes of crop plants species. Genetic regularity is relatively complex, and other crops. Now in its research than less, squash in China after the cucumber cultivation in protected area, but weak light of low temperature resistance of cucumber, tomato far more research behind. In 1980, shanxi academy of agricultural sciences vegetables "green" bred early hybrid generation squash, but in the national still have a large plantation area of varieties, visible the update is very slow. This is the squash germplasm resources innovation, quality breeding the actual operation of the increased difficulties. Since the implementation of this study, innovation a batch of excellent synthetical properties of breeding materials, in breeding for at the same time, the researchers developed a generation of hybrid seed, new techniques for high yield cultivation techniques for high yield and high efficiency. The main research results for the following:1. We have obtained the innovation of superior traits of the material. From the France, the United States 4094 hands series, the Netherlands, South Korea jade dragon peak and other foreign material isolated excellent squash system of 86, 200 system, and from Japan, Korea, sweet chestnut etc dongsheng isolated materials of small table India pumpkin excellent inbred lines 28 anvil, with more than 50 pumpkin inbred lines.2. Obtained a number of new pumpkin breeding varieties. The"Zi Hu 1"and"Zi Hu 3"have high site ability, good marketable, and in 2007-2008 regional trials in shandong province showed resistance,"Zi Hu 1"had the increase 30% more than the controls,"Zi Hu 3"had the increase 10% more than the controls.3. The researchers developed a squash a hybrid for breeding techniques for high yield cultivation techniques and procedures.
