This Week in Nature

In Nature this week, a group of US and Chinese investigators presents a genetic analysis of the improved yields from hybrid rice compared with inbred parent varieties — a phenomenon known as heterosis. They report large-scale genomic mapping for yield-related traits and effects by analyzing over 10,000 rice lines derived from 17 representative hybrid rice crosses, classifying modern hybrid rice varieties into three groups representing different breeding systems.
