Lu original single 4 (the promotion of an area of more than 10 million mu) Lu original single 4 (photos see the back cover) is my so 20 raw maize inbred lines as the female parent, inbred line Wei Feng 322 as the father of this set in 1974, Bred in 1976. In 1981, it had expanded its planting area to 1,000 million mu. The variety of more identification by 1976, the average yield of 853.7 kg, compared with the average increase of 10.76% Lu three 9, early maturity 15-20 days; in 1977 the provincial average yield per mu 864.3 kg, compared with the control smoke No. 6 An average increase of 13.3%. In 1978, three experiments in Hebei and Tianjin increased 30.58% on average compared with Jinghuang 113; five experiments in Henan Province increased 17.46% on average compared with Zheng Dan 2. After years of production demonstration shows that the general per-mu produce 700-800 pounds, in high-fat conditions, large-scale mu produce up to 900 pounds and above. This
