Abstract :1) The authors carried out reciprocal crossings of 111 combinations among Japanese, bulu, aus, boro, aman and tjereh groups of 12 analysing varities, and classification of analysing varieties were tried to base on seed and pollen fertilities of their F_1 hybrids. 2) The Japanese group showed high hybrid affinity to the bulu and aus groups. Their affinity to the aman and tjereh groups was low, and that to the boro group showed middle situation. 3) The seed fertility higher or lower than 87% of seeds from each combination being designated by a plus or minus sign respectively, each group was shown by a combination of six signs (Fig. 4). Having arranged them according to the number and position of plus and minus signs, they were divided into two groups. Japanese, bulu and aman groups belonged to the "First Group", and aman, tjereh and boro were classified into the " Second Group". According to Morinagas' classification, boro group may be considered to belong to the intermediate group. 4) Differences of fertility was found between reciprocal crossings of boro and Japanese groups, boro and bulu groups, and Jp-2 and Am-2.
