Abstract:
In this paper, the agronomic and qualitative traits of 18 sorghum germplasm resources were comprehensively evaluated. The 18 sorghum germplasms from home and abroad were used as experimental materials to determine five agronomic traits including plant height, ear length and 1 000-grain weight, etc and three qualitative traits including protein content, starch content and crude fat content. Variance analysis showed that the agronomic traits of 18 sorghum germplasms differed significantly, extremely significantly or insignificantly. The variation coefficients of agronomic characters and quality characters of the tested materials were significantly different. Five sorghum germplasm with better comprehensive performance were screened by membership function analysis, and the degree of good quality followed as KS 152-1>M-60826>5-46796>Sansuihongke Aigaoliang>Zhe 43 Hui. The results showed that five sorghum germplasms(KS 152-1, M-60826, 5-46796, Sansuihongke Aigaoliang and Zhe 43 Hui) with better comprehensive performance were screened out and could be used in sorghum breeding.
