Abstract
The present study on using "Line x Tester analysis" was conducted to find
out heterosis, inbreeding depression and combining ability on Snap Beans during
years 1999 and 2000 autumn season. The variances due to genotypes were
significant for all characters in both seasons except for vitamin C content in 1999. The
highest percentage of heterosis over high parent for yield per plant was observed in
the cross (2 x 6) in both seasons. Variety Serbo had high GCA for yield per plant in
the two seasons. Estimates of heterosis, GCA (general combining ability) and SCA
(specific combining ability) showed that the best combiners were Serbo and Helda,
while the best combinations were (1 x 6), (2 x 5) and (2 x 6).
