In the conventional cultivation conditions (3 repetitions, three lines for each subregion, for each line, plant spacing 15 cm, line spacing 50cm).The objective of this study is to analyze the correlation between the structure of the growth period and character of yield . The results show that: (1) The grain weight per plant of late maturity material and grain number per plant of late maturity mater
