The necessity of breeding new early variety of wheat existing high correlation between growth habit ahd heading time and ripening period is long over-due in our country. So the work to breed new early varieties as to growth habit dn wheat has been continued at Tokai-Kinki National Agricultural Experiment Station, in Japan. Results of 10 crosses made to study the inheritance of growth habit of wheat varieties, segregation ratios obtained as to erect and prostrate in F_2 are shown in figure 1 and table 2, respectively. Relations between growth habit and lo:eading time, and ripening date are shown in table 3, 4, 5, and 6 respectively. The methods of testing the growth habit and heading, and ripening date :are as follows : the growth habit of F_2 Was decided from the parent and factor hypothesis and factor analysis as shown in report. The results obtained can be briefly summarized as follows : 1. Factors affecting the growth habit of wheat correspond to 3 genes. 2. E factor is epistatic to P and T factor, P factor is medium and T factor is substatic to E and P factors. 3. E factor determines erect-type, both P and T factors control prostrate-type, but differ in their effect on prostrate. 4. Factors affecting growth habit and heading time and ripening period on wheat seem to be the same.
