内容記述(抄録等)
(1)After researching the resistance of rice plant to stem maggot, Chlorops oryzae MATSUMURA, throughout 5 years' experiments, 43 varieties of rice plant were classified into 3 groups of different resistance from the relationship of the heading date and the percentage of injured ears of them.
(2) The curves representing each group of different resistance were drawn after theoretical formulaes. Judging from the annual variation of the curves and their climatic reason, the higher temperature in March may be taken to indicate the appearance of the date of maximum point of curve in more early stage and the one in June and July to lessen the percentage of injured ears.
(3) Judging from the relationship between F_2 individuals and F_3 strains; the true resistance of rice plant might not appear rather in thease years when the plants injured severely.
