    Heterosis for quality traits in tomato
    (Kerala Agricultural University, Vellanikara, 2001) Alice, Kurian; Peter, K V
    Quality improvement of bacterial wilt resistant / tolerant tomato accessions was attempted by crossing with selected processing varieties. The Fl hybrids which showed the highest per se performance were Sakthi x HW 208 (9.18%) for total solids, Sakthfx HW 208F for insoluble solids (0.91%) and consistency (0.31), LE 206 x St 64 (7.0%) for TSS and LE 206 x Ohio 8129 (11.66 mg lOOg'1) for lycopene. Highest significant heterobeltiosis was expressed by the Fl hybrids Sakthi x TH 318 (for total solids), LE 206 x St 64 (for TSS, lycopene) and Sakthi x Fresh Market 9 (for consistency). The Fl hybrids, though showed improved fruit quality in terms of uniform ripening, high lycopene and total solids and resistance to cracking, were completely susceptible to bacterial wilt. Bacterial wilt resistant segregates with desirable fruit quality could be isolated from the F2 generation.

    Heterosis for yield components and fruit characters in tomato
    (Kerala Agricultural University, Vellanikara, 2001) Alice, Kurian; Peter, K V; Rajan, S
    Heterosis for yield components and fruit characters was studied using line x tester analysis between bacterial wilt resistant / tolerant accessions and processing varieties. Heterotic hybrids were identified for average fruit weight (Sakthi x Fresh Market 9, Sakthi x HW 208F), yield / plant (Sakthi x TH 318, Sakthi x Fresh Market 9), locule number (LE 206 x Ohio 8129, LE 214 x St 64) and pericarp thickness (Sakthi x St 64, LE 206 x 64, LE 214 x St 64). All the hybrids were late to harvest and they produced fruits with round shape.
