The inheritance of bean forms in Arabica coffee
A quantitative study on bean forms in arabica crosses S288 x Ab 7 and S795 x 1 Jember was made on the Blawan and Kalisat estates of PTP XXVI, during the 1983 harvest. The quantitative estimations included the correlation of bean forms, the heritability, the gene actions, and the gene controls. Based on this study it could be estimated that normal and round beans were highly positively correlated; round as well as normal beans had a high negative correlation to elephant beans. The heritability of normal, round, and elephant beans were estimated at 73,20, 29,03, 0.01, respectively. The gene actions for normal beans were overpositively dominant in both crossings. Round and elephant beans in S 288 x AB 7 crossings were respectively overnegatively and overpositively dominant; and in S 795 x 1 Jember crossings were overpositively and partially positively dominant. It seemed, that elephant beans were controlled by polygenes, while round beans by monogenes. Genes which controlled normal beans on the other hand were still doubtful. To secure more solid conclusion research work on these matters will be continued in the next harvest year of 1984
