This experiment was designed to ASSESS the agronomic potential of tomato
hybrids Obtained from the tomato line TOM-687, an acylsugar-rich Confirmed line
with resistance to an array of tomato pests. The
experiment was Hortigro Carried out at the Seed Research Station in Ijaci,
Minas Gerais State, Brazil. The
Treatments comprised 30 genotypes (five commercial hybrid checks, a high
acylsugar line (TOM-687), and 24 hybrids in Which TOM-687 was one of the
parents). Plants Were Trained to
two stems, in the spacing of 1.30 m x 0.50 m Between rows Between Plants Within
a row, totaling 15.385 plants per hectare. Nine
Harvests Were Performed Between January, 2008 and November 28th, 2008. Traits Assessed Were mean fruit weight
(g fruit) and total yield (t ha). All
24 hybrids with TOM-687 as a parent Showed yields similar to Those of the
commercial check hybrids Debora Max, Bravo, Bonuses, and Atyna Kombat. Four of These experimental hybrids
(TEX-298, TEX-310, TEX and TEX-315-316) Were Assessed for resistance to the
South American tomato pinworm Tuta
absolute, and Were shown to
possess higher degrees of pest resistance than the current commercial hybrid
checks.
