VANCOUVER, British Columbia, Nov. 2, 2010 (GLOBE NEWSWIRE) -- GLG Life Tech Corporation (Nasdaq:GLGL) (TSX:GLG) ("GLG" or the "Company"), the vertically-integrated leader in the agricultural and commercial development of high quality stevia, announces that its stevia seed propagation program has been successful and that the Company's new Huinong Two ("H2") proprietary stevia variety has produced enough seeds to fulfill the majority of requirements for the next stevia planting season. The new seeds provide GLG a significant cost advantage due to very high levels of rebaudioside A naturally present in the new stevia strain.

The H2 strain contains approximately 66% rebaudioside A in the plant leaf. Rebaudioside A is the sweetest component of the stevia plant and the primary glycoside used to meet the market demand for stevia sweeteners. GLG's H2 strain has yielded 10% higher rebaudioside A content than the previous generation (H1). In addition, the H2 strain also generates 22% more leaf per acre. GLG plans to upgrade its varieties company wide and to utilize its new H2 strain at all 12 of the Company's growing bases in China for the 2011 crop season.

GLG also announces that an H3 generation is on track to be commercially available for its farmers in the 2012/2013 stevia planting season. The GLG agricultural R&D team has already completed the most difficult steps in developing a commercially viable new natural strain. The H3 generation will now enter the final stages of commercial plot testing and seed propagation which is expected to take one to two years to complete. The H3 proprietary strain results show the following improvements in yield:
  • 76% rebaudioside A content in the leaf, a 26% increase from the H1 strain
  • An estimated 600kg of additional stevia leaf harvested per acre, a 46% increase over H1, which improves land and resource utilization
  • An estimated 40% overall leaf cost improvement expected as a direct result of the increased RA content and increased leaf yield
  • Greater processing efficiencies expected

All improvements to GLG proprietary seed strains are through natural breeding methods.
