Abstract

In order to study the relationship among various morphological and physiological traits, yield components and grain yield in grain SORGHUM (SORGHUM bicolor), a field experiment was conducted in 1373 at Isfahan. Path coefficient analysis of correlation coefficients revealed a complex pattern of relationship among traits. This pattern was partly hidden in superficial study of correlation coefficients. Path coefficient analysis showed that in determination of vegetative dry- matter (VDM), this order of contribution was true: Leaf area index > Plant height > Days to anthesis > Leaf number. VDM had a negative influence on number of kernels per unit area: kernel number was the most important yield component. Late-maturing, via increasing of VDM and decreasing grain filling rate per unit area, reduced grain yield. Then, in view of relationships among traits and significance of the traits to YIELD FORMATION. a SORGHUM ideotype proposed for Isfahan.
