Selection strategies for fruit yield in tomato (Solanum lycopersicum L.)

Abstract

The study was initiated to generate genetic information on characters associations for tomato genotypes maintained under Chhattisgarh conditions. Nineteen tomato (Solanum lycopersicum Mill.) genotypes were evaluated to estimate the nature and magnitude of associations of different characters with fruit yield and among themselves at College of Agricultural Raipur (C.G.)
during Rabi Oct 2008 to Feb 2009. The genetic parameters, character association path coefficient analysis between yield and yield contributing characters of different tomato genotypes were studied. The genotypes exhibited a wide range of variability for all the traits studied. The traits were also found to be highly heritable. From the parent study it could be concluded that improvement in fruit yield of tomato could be brought by indirect selection for the days to first flowering.
