The best area for seed production

Although the rainfall in Jiuquan area is very low (only 80 mm per year), there are still enough water for irrigation due to the 5,600-meter height of Qilian Mountain with eternal covered-snow extending on the south side of it.

Summer time in Jiuquan area is quite cool, whose day temperatures ranging from 25 – 30°C, and night temperatures around 15°C. Winter time is very cold, whose minimum temperatures can be extremely minus 35°C. Note that the Maximum and Minimum temperatures listed in the below chart, are the MEAN data for that month.

In such a cold winter, bacteria and insects will be killed by frozen earth. It is important for phyto-sanitary, that's why we can supply seeds with the most strict demand of phyto-sanitary certification and additional declaration.

As mentioned above, the rainfall in Jiuquan is about 80mm per year, but the water evaporated is quite a lot, which is about 2100mm per year. Such a drought condition is a threat to agriculture to some extent, but it’s good for seed airing.

In a word, the unique geographical and climatic features in Jiuquan bring many advantages in seed producing.

Protection of genetic material is the most important thing in let production of seeds. As our contract farmers and growers have been working with us for several years, they well understand the principles of genetic ownership and anyone who goes against the protection of genetic material will be expelled from the seed production group. Meanwhile, contract seed production under customers’ demand is the sole business of Topsource, we don’t sell any seeds except those surplus of over-production with customers’ consent.

For that hybrid F1 seed production, we usually plant male line seedlings in our own plastic house while those of female line in grower’s field. Currently we are studying some new genetic protection method like cryo-pollen hybrid seed production, which adopts cryopreservation of pollen.
