Biography

Li Zhensheng, male, Han nationality, is a native of Zibo, Shandong Province. He graduated from Shandong Agronomy College.

Among his many accomplishments, Li succeeded in breeding new crossbreed types, such as small couchgrass wheat octoploid, iso-additional series, iso-replacement series and ectopic series. He also successfully transferred certain genes of couchgrass, including drought endurance, dry and hot air withstanding and multiple wheat diseases resistance. He later succeeded in breeding new small couchgrass wheat types: Nos.4, 5 and 6. No.6 small couchgrass wheat had been accumulatively popularized to 54 million mu per till in 1988, an output increase of 1.6 billion kilograms.

Li also established a new system for wheat chromosome engineering breeding. He made use of the blue albumen gene of couchgrass as a genetic mark character and led the creation of blue monomer wheat system. He solved two complicated problems in the monomer wheat utilization process: 'single-valence chromosome excursion' and 'excessive workload in appraising chromosome quantity.' He also succeeded in breeding nullisomic wheat self-fruit bearing and made use of nullisomic wheat inaugurating a new method of quick selectively breeding iso-replacement series - nullisomic backcross method, laying the foundation for wheat chromosome engineering breeding.
