Screening Test of New Sesame Varieties in Lime Concretion Black Soil Area of Zhumadian
[Objective]The aim was to screen out new sesame varieties suitable for planting in lime concretion black soil area of Zhumadian,and promote the healthy development of sesame industry in Zhumadian.[Method]With Yuzhi 4 as the control variety,10 varieties of Zhu 22B03,Zhu 22B07 and other units provided by Zhumadian Academy of Agricultural Sciences were evaluated in terms of economic traits,yield performance and resistance.[Result]The average number of capsules per plant of all tested varieties(lines)was 76.2-92.3,and that of Zhu 22B03 was the highest.The average number of grains per capsule was 61.30-70.12,and that of Shangzhi 10 was the highest.The average 1000-grain weight ranged from 3.098 g to 3.430 g,and that of Shangzhi 10 was the highest.The incidence and disease index of Fusarium wilt and stem blight of Zhu 22B03,Zhu 22B07,Shangzhi 10,Yuzhi 23,Xinzhi H12 were lower than those of the control varieties.In terms of yield,10 of the 12 tested varieties(lines)increased yield compared with the control.Among them,Zhu 22B03 had low initial capsule height,many effective nodes,the largest number of capsules per plant,high 1000-grain weight,high resistance to Fusarium wilt and stem spot blight,and the highest yield of 1799.3 kg/hm2,which was 30.89%higher than that of the control.[Conclusion]Based on the performance of new varieties(lines)in agronomic traits,stress resistance and yield,Zhu 22B03,Zhu 22B07,Shangzhi 10,Yuzhi 23 and Xinzhi H12 showed excellent performance in all aspects,which could be popularized and applied in Zhumadian lime concretion black soil area.
