| Abstract:
Tomato is one of the most important vegetable crops of the world and is known for its versatile uses. Eleven F1 hybrids identified on the basis of superior performance during the preceding years were evaluated for various horticultural traits over two years viz. 1999-2000 and 2000-2001. The two check hybrids included were TH 802 and Avinash-2. The ANOVA revealed that there existed significant differences among the hybrids for all the characters studied when analyzed for individual years and also when pooled over the years. The MS due to years were significant for TSS, fruit weight and total yield. The interaction between years x hybrids was significant for all the characters studied except for fruit shape index. TH-4 out-yielded Avinash-2, better of the two checks, by 35.8 per cent. TH-1 and TH-2 recorded identical yields and out-performed Avinash-2 by 27.1 per cent. TH-1 was significantly better than both the checks for number of locules and TSS. TH-2 was significantly better than both the checks for number of locules and pericarp thickness and was at par for TSS. Three hybrids viz. TH-1, TH-2 and TH-4, identified on the basis of superior performance in the field were evaluated for biochemical constituents important for processing. Based upon the field performance and the laboratory analysis, hybrid TH-1 was found suitable both for fresh fruit market and processing and hybrid TH-2 for processing. | |
