Heterosis for yield and yield attributing traits in tomato (Solanum lycopersicum L.)

Abstract

Six diverse lines of tomato were crossed with four testers in
line x tester (L×T) cross design to investigate the extent of
heterosis for yield and its contributing traits in tomato. The
present investigation was carried out under AICRP on
Vegetable Crops at Horticultural Research cum Instructional
Farm, Department of Vegetable Science, IGKV, Raipur (C.G.)
during rabi 2017-18. A high degree of heterosis was
observed for most of the characters under investigation.
High per se performance with remarkable heterosis were
expressed by PR x 14/TLCV-3, KA x 15/TLCV-2, H-86 x 14/
TLCV-3, KA x 14/TLCV-3 and H-24 x 14/TLCV-1 for higher
fruit yield, however, a high degree of heterosis for other
traits in desired direction was also observed
