Abstract: Six cycles of latticed mass selection for grain yield and correlated character properties were conducted in Zhong Zong No.3(ZZ3)from 1995 to 1996 at three locations. The grain yields of population showed significant response to the selection. The evaluating experiments showed that the average yield increase per cycle was 192.45 kg. ha-1(4.01%), and the linear response was 187.80 kg. ha-1. The yield gains are associated with the increase of ears. After six-cycle selection, the ear length gained 1.8 cm(12.7%)for the advanced cycle vs. the original population. Number of kernel per row and 1000 kernel weight increased 4.1 kernel(10.9%)and 27.2 g(12.5%), respectively. The plant height and ear height of advanced cycles were increased 29.2 cm and 17.8 cm respectively. The ratio of lodging and wilted plant were decreased significantly to 12.1% and 9.6% in the final cycle.
