| Abstract: | An analysis on the effects of bacterial leaf blight (Xanthomonas cam-pestris pv.oryzae) to main economic traits of hybrid rice was made inHangzhow in 1981.The results suggested that when the inoculationwas practiced at booting stage,the numbers of filled grains per plant,1000-kernel weight and grain yield of an individual plant were de-creased but empty husk per plant increased with increasing of degree ofsusceptibility in Nanyou No.2 and some other combinations,whichwere highly susceptible to KS-6-6,a virulent isolate used in the study,while the most of economic traits were generally not affected due to lowdegree of susceptibility in Shanyou No.6 and Weiyou No.6.Pathcoefficients of degree of susceptibility to grain yield per plant were lowin all eight combinations but indirect effect was high through numbers offilled grains per panicle and 1000-kernel weight,suggesting that degreeof susceptibility indirectly affect grain yield through numbers of filledgrains per panicle and 1000-kernel weight,etc.. |
