Abstract: The different methods belonging to planting direct were analyzed in order to find out appropriate one to evaluate genetic yield gain based on our experiment. Maize hybrids, spanning four decades (from 1970s–2000s), and representing the main maize areas in China and the most popular hybrids of their time were tested during 2005–2006 and 2007–2008 in Beijing and Xinjiang. Trials were conducted under three plant densities. The difference between the yield of the 1970s hybrids with 30 000 plants ha-1 and the yield of the 2000s hybrids was divided by 40 years, providing an estimated genetic yield gain per year of 94.7 kg ha-1. The difference between the yield of the 2000s hybrids and the yield of the 1970s hybrids with 75 000 plants ha-1 resulted from genetics. The difference between the yield of the 1970s hybrids with 15 000 plants ha-1 and the yield of the 2000s hybrids with 75 000 plants ha-1 was due to breeding and management. The ratio showed the contribution of breeding to total yield gain was 52.9%. Direct planting method proposed by Duvick was applicable to evaluate the genetic yield gain. The experiment design conducted by Tollnaar was applicable to evaluate the contribution of genetics to total yield gain.
