Popis:	The performance of very early ripening satsuma mandarin (C. unshiu Marc.) 'Yamakawa' grafted on 7 different rootstocks in 1988 was examined from 1994 to 1998. The growth of the scion grafted on Shiikuwasha, Rangpur lime, 'Citrumelo' and Volkameriana was superior to that grafted on trifoliate selections (trifoliate orange, rubidoux trifoliate and 'Flying Dragon'). 'Citrumelo' had the highest cumulative yield from 1994-8. Although the highest Brix was found in fruits borne on 'Flying Dragon' and 'Citrumelo' rootstocks, fruit quality was slightly higher but the yields were lower on trifoliate selections. In trees on 'Citrumelo', the mean top/root (T/R) dry weight ratio was 1.77, indicating that a disproportionate amount of the total dry matter was partitioned to the aerial parts of the tree. Based on tree vigor, yield, and fruit quality, 'Citrumelo' is considered to be the most suitable rootstock for very early satsuma mandarin 'Yamakawa'.
