Abstract

Tomato is the most important vegetable crop in the world and in India for its nutritional and industrial value. The production and productivity of tomato in India is less compare to world scenario due to plants basically succulent in nature so more prone to infestation by biotic and abiotic stresses. So there is need of new and improved tomato lines which were high yielded and resistant to biotic and abiotic stresses. In this experiment we have developed a total of 147 recombinant inbred lines from the cross Anagha and FBT-41, which are contrasting for the trait bacterial wilt disease resistance. Among 147 lines developed and evaluated for 18 yield and quality traits a total eight lines were identified as superior inbred lines viz., TRIP2-8, TRIP2-17, TRIP2-18, TRIP2-20, TRIP2-22, TRIP2-24, TRIP2-35 and TRIP2-110, so these high yielding homozygous lines can be directly released as variety after necessary multi location trials or can be used as parent to develop hybrids.

Conclusion

Considering all the yield and quality traits in the 147 RILs derived from the cross Anagha × FBT-41, eight lines were identified as superior inbred lines viz., TRIP2-8, TRIP2-17, TRIP2-18, TRIP2-20, TRIP2-22, TRIP2-24, TRIP2-35 and TRIP2-110. This lines homozygous stable lines can be used to developed hybrids which were high yielders or can be released as variety directly for cultivation.
