| dc.description.abstract | The present studies entitled “Hybridization studies in Tomato (Solanum lycopersicum L.) through Diallel Mating Design” were carried out at the Vegetable Production Block (under protected condition), Tigaddu during the year 2016-17. The experimental material for the present study comprised of six parents and F1 population of fifteencrosses, developed by crossing these six diverse tomato lines in diallel design (excluding reciprocals). All theparents and their hybrids along with the standard check (Arka Rakshak) were planted in a Randomized Complete BlockDesign for their evaluation in December, 2016. The observations were recorded on plant height (cm), number of fruit clusters per plant, number of fruits per cluster, number of fruits per plant, fruit length (mm), fruit breadth (mm), average fruit weight (g), fruit volume (mL), marketable fruit yield per plant (Kg), harvest duration (days), pericarp thickness (mm), shelf life (days), TSS (0brix), ascorbic acid (mg/100g) and whitefly infestation (%). The analysis of variance indicated highly significantdifferences among the genotypes for all the traits studied. Experimental results revealed that two lines viz, AVTO-9001 and Sioux were found superior on the basis of mean performance and general combiningability studies. Four cross combinations viz, Solan lalima × Sioux, LC-9 × Sioux, Sioux × Arka Meghali and AVTO-9001 × Sioux were found best on the basis of meanperformance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be testedfurther at multiplications before releasing as a substitute of already existing hybrid varieties of tomato. Gene action studies indicated predominance of dominance effects in governing mostof the traits suggesting exploitation of hybrid vigour and developing hybrids for improvement of these traits intomato on the basis of present studies. | en_US |
