GENETIC VARIABILITY STUDIES IN F2 SEGREGATINGPOPULATION OF INDETERMINATE TOMATO (SOLANUMLYCOPERSICUM L.) GENOTYPES UNDER PROTECTEDCONDITIONSM.N. Nikhil Gowda, V. Srinivasa*, Devaraju, D. Lakshmana, S.K. Nataraj and M.N. SharathAbstract A field study under protected conditions was conducted to assess genetic variability for yield and yieldattributes in an F2 segregating population of tomato cross EC521069Ã EC362941.The experiment was carriedout during 2021â2022 at the College of Horticulture, Mudigere, in an augmented block design. Analysis ofvariance showed highly significant differences among the traits.High values of PCV and GCV were registeredfor number of fruits per plant, fruit yield per plant, fruit volume and average fruit weight. Estimates of highheritability coupled with high genetic advance as per cent over mean recorded for plant height, number offlowers per cluster, days taken from first harvest to last harvest, fruits per cluster, fruits per plant, fruityield per plant, fruit length, fruit diameter, fruit volume, average fruit weight and pericarp thickness whichsupports the notion that selection could actually improve these traits by highlighting the significance ofadditive gene action. |
