To find the magnitude of variation of total non-structural carbohydrate(TNC) and total nitrogen content and 25 other characters that measured from 105 Sorghum cultivars, and their interrelationships, this experiment was carried out from 1. April to 1. December 1976 at the experimental Farm of the College of Agriculture, Korea University, that located Wa-bu myon, Yang-ju county, Kyong-ki province, Korea under the financial support from Ministery of Science and Technology of Korea. Completely randomized design was employed and replicated three times. Considerable variation was observed from all measured characters, including both TNC and total nitrogen contents. Breeding for both characters seemed to be of fair economic return. High correlation was found between TNC and its components, and one of them would be used as a representative of this character to make screening process for TNC easy. Except NO₃-N there was no significant correlation between total nitrogen and its components. This seemed to indicated the much more complicated physiological and genetical control of biosynthetic pathway of nitrogen than that of TNC. Parallel increase of total nitrogen and NO₃-N content would be possible and this requires cautions in selecting breeding material for nitrogen. With dry matter, considerably high correlation was found with stem weight, leaf weight and leaf sheath weight. Among them, stem weight showed the highest correlation with dry matter, indicating this is the main component of dry matter. To breed high quality and yield forage sorghum, much consideration is needed for this.
