Five commercial tomato (Solanum lycopersicum L.) cultivars and their ten F1 hybrids were
used in order to detect the general performances and estimation the heterosis percentages …

Heterosis and combining ability are two important considerations in the utilization of
heterosis, which can be used to generate excellent hybrid resource candidates and is very …

Magnitude of heterosis, combining ability effects and its variances were estimated by line×
tester analysis including 30 F1 cross combinations using 13 parents after selfing (ten lines …

The objective of this work was to evaluate four parental lines of cucumber which
included:'Zeina'(Zna),'Beit Alpha'(BA),'Straight 8'(Strght 8) and 'Calypso'(Capso) and six F 1 …

SUMMARY A study was conducted to determine the types of gene action of different yield-
related traits in tomato and the combining ability in four advanced lines. The heterotic …

The objectives of this study were to determine heterosis and the type of gene action
controlling some economical traits of tomato. Six populations of the cross CastleRock× CLN …

Tomato is a pivotal vegetable crop worldwide concerning human nutrition, economy and in
service to biotechnology. Tomato leaf curl virus (ToLCV) is a begomovirus transmitted …

Postharvest losses are the main constraints in tomato production. Several approaches were
used for increasing the shelf life of tomatoes. Use of ripening mutants is one such strategy. In …

Paucity of research on the development of tomato hybrid having desirable post harvest/or
processing quality in the tropics compel to undertake this study. Therefore, the present …

Heterosis for yield components and yield per plant was studied using 7x7 half diallel cross
between bacterial wilt-resistant/tolerant genotypes and high-yielding varieties. The heterosis …
