Performance of twenty five recombinant tomato hybrids fortheir flowering parameters and physical fruit parameters

Abstract

The field experiment was conducted at new orchard of the Main Agricultural Research Station, Dharwad duringthe year rabi 2019-20 to study the performance of twenty five recombinant tomato double cross hybrids(Solanum lycopersicum L.) for their physical fruit parameters and flowering parameters. All these 25 genotypes showedsignificant variation with respect to physical fruit characters and flowering characters. Physical parameter viz., fruit length(mm), fruit diameter (mm), fruit shape, fruit shape index (%), fruit color, and flowering parameters like days to 1st floweringand days to 50% flowering showed notable variation in all the tomato double cross hybrids. The hybrid line NS-526 xShankara and Abhilash x S-85 recorded significantly higher fruit length (55.35 mm). However, the genotype MHAT-306 xSindu showed the highest fruit girth (66.28 mm). The highest fruit shape index was reported in KTH-354 x Sagara (1.12%)line. Days to first flowering and minimum days to 50 percent flowering were observed in KSP-1326 x Shankara (14.50,18.50 days, respectively) and MHAT-306 x NS-585 (14, 19.50 days, respectively).
