Selection of new maize varieties suitable for small-scale mechanized planting in mountainous area

A new maize variety suitable for small-scale mechanized planting was selected by split plot design. The results showed that there were 3 varieties with good grain distance qualified index, 3 varieties with low reseeding rate and 3 varieties with low missing seeding rate Three varieties with good uniformity of plant height and two varieties with good uniformity of spike height were obtained by analysis of uniformity of population, and five varieties with good uniformity of bract leaf were obtained by analysis of character of bract leaf. Comprehensive Consideration, there are three new maize varieties suitable for small-scale mechanized planting in mountain areas, namely Zhongdan 901, jade 007, Jingnongke 728.
