Main Agronomic Characters Correlation Analysis on Twelve New Sesame Varieties in Zhoukou Ecological Region

In order to provide reference for breeding new sesame varieties,main agronomic traits were analyzed by comparison and correlation analysis twelve new sesame varieties.The test results showed that the varieties Zhou 10 J5,Zhu 11 J19,Zhouzhi No.5 had higher yield,higher disease resistance and better comprehensive characteristicss in the twelve new sesame varieties;the correlation analysis showed that the yield were positively correlated with seeds plantcapsule,grain yield per plant,capsules,length of fruiting section,plant hight,per 1000 seed weight,void length,negatively correlated with first capsule height.In the high-yield sesame variety breeding,moderate plant hight,lower first capsule height,longer length of fruiting section,more capsule,more seeds plantcapsule,higher per 1000 seed weight were significantly selected.
