Evaluation of F1 Hybrids along with Parents for Yield and Related Characteristics in Tomato (Solanum lycopersicum Child)

Abstract

Eight diverse homozygous tomato parental lines were crossed in half diallel fashion, to develop twenty-eight hybrids. These 28 F1 hybrids and their parents were evaluated at Department of Vegetable Science, C.H.F., CAU, Pasighat, A.P. during 2014-2015. A wide range of variation was observed for fruit yield and related constituents. The high PCV, GCV, ECV, heritability (broad sense), and genetic advance over percentage of mean were recorded for fruit yield per plant. DVRT-1 × CHFT-50 was found earliest flowering in 50.67 days and earliest harvest in 70.00 days. Earliest flowering concurrent with early fruit set that are expressed in all hybrids under studied. The highest fruit yield was established in DVRT-2 × CHFT-77 (9.13 kg), followed by DVRT-2 × H-86 (6.86 kg) and CHFT-60 × CHFT-71 (5.92 kg). Among the hybrids, the fruit weight was correlated with fruit yield. Cross, H-86 × CHFT-50 was given high yield along with quality characters. The hybrid DVRT-2 × CHFT-77, H-86 × CHFT-50 and CHFT-60 × CHFT-71 were found best regarding fruit yield, quality traits and earliness. Therefore, the current study showed that hybrid breeding approaches strengthening to improve yield, earliness together with qualities.
