【Abstract】 A new inbred sorghum‘Shen 1347’ was studied on relationships between its typical characters and yield. The results showed that, the growth period of inbred sorghum ‘Shen 1347’ is about 120 days in Shenyang. Plante height is 1.6-1.8 m. 1000 grain weight is about 27-31 g. Its erect leaves fit for higher plant density and have higher economic coefficient,so it can get high yield under the high density. The characters, such as leaf area, leaf angle, grain weight per ear and so on, have greater variation coefficients and significant correlation with yields, so it should be regulated by optimum cultivation.更多还原
