Abstract

This research was conducted to investigation of traits correlation and the cause and effect relationship among some traits and yield component in sugar beet in salt conditions, the research was conducted in the experimental field of Agriculture Faculty of Ahvaz University. The experimental design was split plot based on RCBD with three replications in determine the most important Affecting sugar yield of sugar beet (beta vulgaris) in saline soil. Main plot were two planting treatment (direct and paper pot transplanting), and sub plot were 3 cultivar (BR1 technical monogerm, monodora and BR1 moltigerm). Results showed that the simple effect of cultivation methods had significant difference and PAPER POT CULTIVATION was better than direct cultivation. PAPER POT CULTIVATION had sugar percentage more than direct cultivation. The highest sugar yield obtained in cultivation. According to the results the highest positive correlation between root weight and other traits depended on total fresh and dry weight and root dry weight respectively. Root yield had negative correlation with net and gross sugar percentage, and positive correlation with other traits. To remove the effects of ineffective or low impact from the performance characteristics of sugar beet roots in the regression model was used STEPWISE REGRESSION. In this article the important traits of sugar beet yield included root dry weight, total fresh weight, leaf fresh weight, and collar fresh weight. R2 of model was 0.9994, which means those traits can justify approximately 100 percent variation of root yield. Result of PATH ANALYSIS had showed fresh weight has the most direct and positive effect on produced root and by root dry weight and indirect and negative collar fresh weight traits and by total fresh weight indirect effect on yield. There was a positive correlation among accessible sugar with total dry weight and root fresh weight. Accessible sugar put three traits in to regression model based on STEPWISE REGRESSION model and this variation justify sugar. Root fresh weight can justify only 0.91 variations. Based on PATH ANALYSIS root fresh weight had direct and positive effect and sugar percent had the lowest direct and negative effect on accessible root yield.
