A study on the combining ability in Chilli Pepper (Capsicum annuum L. And Capsicum chinense jacq.) using line x tester analysis [electronic resource].

Includes reference.

Seven chilli pepper PIs obtained from USDA were used in this study. Four PIs belong to Capsicum annuum, viz., 159233, 138563, 142837and 166988 (used as line) and three PIs belong to Capsicum chinense, viz., 209028, 159241 and 159236 (used as tester) were crossed in a line x tester mating design to calculate the effects of the combining ability for eight characters, plant height, earliness, average fruit weight, fruit diameter, fruit length, fruit flesh thickness, early yield and total yield during 2005-2006 under unheated plastic house at Kaha Experimental Station, Kaliobia Governorate. Significant differences were found among the tested genotypes for all studied traits except for fruit flesh thickness. The non additive gene effect played the major role in the inheritance of all characters except for the number of days to flowering. General combining ability (GCA) estimates for the parent P1166988 showed that it was the best parent for early yield. Specific combining ability (SCA) estimated for the cross PI 166988 x PI 159236 showed that it was the best cross for plant height, number of days to flowering, average fruit weight, fruit length, fruit diameter and total yield.
