Evaluation of relationship between grain yield and yield components in Sesame genotypes
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 16
Abstract
In order to evaluate the grain yield and yield components in Sesame genotypes, an experiment was conducted on 25 internal and external agricultural Sesame in a randomized complete block design in research farm of Khair Abad located in the city of Zanjan, Tarom. The traits were included: how to classify, grain color, being fluffy, number of capsule at leaves base, number of capsules per plant, number of rows in the capsule, number of grain per capsule, grain yield, ripeness date, seed weight and plant height. The results showed that there was significant difference between the studied genotypes in terms of all traits except for plant height and grain weight at 1% level. The results of calculating the correlation coefficients indicated that the relationship between grain yield and number of grain per capsule was negative and significant. Also, the results of stepwise regression analysis showed that the number of grain per capsule was the first variable entered to the model which justified only 0.278 of the variations. Finally, the model coefficient reached to 0.389 on the ripeness days. The regression coefficient for the number of seeds per capsule was negative and day to ripeness was also positive. Therefore, these two traits can be introduced as effective traits on the yield.
