ABSTRACT
The present investigation was analysed to study the extent of heterosis in fifteen cross combinations for yield and quality characters. Six diverse tomato cultivars/ lines viz,
AVTO-9001, LC-9, Sioux, Solan Lalima, Arka Meghali and LC-4 selected on the basis of high yield coupled with high quality aspects were crossed in 6×6 half diallel fashion with
Arka Rakshak as check cultivar/line. Solan Lalima × Sioux was the best cross combiner among fifteen cross combinations with significant positive heterosis for all three types with respect to marketable fruit yield per plant and for quality aspects such as (TSS, Ascorbic acid and Pericarp thickness). Most of the hybrids manifested significant heterosis for number of fruit clusters per plant, number of fruits per cluster and number of fruits per plant. AVTO-9001× Sioux had the significant standard heterosis for fruit volume which has direct impact with average fruit weight. All cross combinations showed negative standard heterosis for whitefly infestation indicating more resistance in hybrids than check.
Keywords: Heterosis, Half diallel fashion.
