Century's Old Genetic Breeding Puzzle Solved
On the basis of his 15-year hard work, Prof. Wu Zhongxian of Chinese Agriculture University has proposed the concept on analyzing the hybrid advantages in association with genetic capacity rather than with matching capacity, which has provided an answer to the century-old puzzle.
The so-called hybrid genetic capacity proposed by Prof. Wu Zhongxian is a new genetic parameter with its values ranging from 0 to 1. When the hybrid is made on several consecutive generations, the hybrid genetic capacity gets improved accordingly. When the improvement approaches 1, all the hybrid generations thereafter will present a same property, which means they have become a new species. The authoritative experts believes that Prof. Wu's new inventive theory on hybrid genetic capacity has theoretically united the analytical approaches of two major areas of breeding sciences: pure breeding and hybrid breeding and is of great importance to guide the production of hybrid animals and plants.
