Abstract

Sln. 3R (CxR) is a hybrid variety of coffee evolved by the crossing of Coffea congensis x Coffea canephora. Sibmating was carried out for the further improvement of CxR and fourteen sibs were evolved. Evaluation of the sibs indicated that Sib 4, Sib 5 and Sib 7 recorded better yield, grade, quality and intermediate plant size. The present study is an effort to compare the seedling vigour and juvenile performance of these sibs with that of Sln. 3R (CxR). Significant differences were observed in leaf area among the four accessions. Maximum leaf area, maximum length of primary roots, maximum seedling height and leaf breadth were recorded in Sln. 3R (CxR), whereas minimum internode length was observed in CxR Sib 7. Analysis of overall performance at juvenile stage also indicated better performance of CxR seedlings over the sibmated progeny.
