Abstract

The research on varietal screening of rice against leaf folder, caseworm and grasshopper damage was conducted during 2019 in Rampur, Chitwan to study the host plant resistant of different varieties of rice under field condition. The experiment was laid out in RCBD with three replications and seven treatments namely i) Makawanpur -1 ii) Mansuli iii) Radha-4 iv) Ramdhan v) Sabitri vi) Sama Mansuli sub-1 and vii) sukkha-3. The experiment revealed that lowest population of leaf folder, caseworm and grasshopper was recorded in variety Radha-4 followed by Ramdhan. The experiment showed the yield loss was significantly lower in Radha-4 followed by Sabitri and Ramdhan due to leaf folder, caseworm and grasshopper. So Radha-4 and sabitri would be good option in rice production for reducing insect pest damage.

田间条件下水稻抗弯叶虫、虫和蝗灾基因型的评价
2019年,在Chitwan的Rampur进行了水稻抗弯叶虫、酪蛋白虫和蚱蜢危害的品种筛选研究,以研究不同品种水稻在田间条件下对寄主植物的抗性。实验在RCBD中进行,有三个重复和七个处理,即i)Makawanpur-1 ii)Mansuli iii)Radha-4 iv)Ramdhan v)Sabitri vi)Sama Mansuli sub-1和vii)sukka-3。试验表明,品种Radha-4的折叶虫、酪蛋白虫和蚱蜢种群数量最低,Ramdhan次之。试验表明,Radha-4的产量损失明显较低,其次是Sabitri和Ramdhan,原因是折叶虫、酪蛋白虫和蚱蜢。因此,Radha-4和sabitri在水稻生产中是减少害虫危害的好选择。
