Phenotypic and postharvest characterization of potential tomato (Solanum lycopersicum L.) lines for mid-elevation farmers of Northern Mindanao, Philippines

Tomato production is extensive in the highlands of Misamis Oriental in Northern Mindanao but the rampant occurrence of Tomato yellow leaf curl virus (TYLCV) which almost wipe-out its tomato industry calls the need for identification of promising tomato lines for small scale growers to sustain.
The objective of this study was to evaluate the performance of four promising tomato lines acquired from AVRDC (AVTO 0101, AVTO 1004, AVTO 1007, and AVTO 1008) for yield, resistance to TYLCV, and fruit quality traits including its shelf life.
Tomato lines AVTO 1004 and AVTO 1008 in terms of weight of fruits harvested per plant and TYLCV severity rating, respectively, are significantly better if not just comparable with the check cultivar at certain cropping periods.
Fruits harvested from AVTO 0101 have more number of locules but the width of its pedicel scar is significantly bigger than all other entries.
Consistently in both cropping periods total soluble solids of AVTO 1007 and 0101 were significantly higher than the check cultivar.
Longest shelf life was observed from AVTO 0101 though it also exhibited significantly higher weight loss upon termination but statistically comparable to the check cultivar.
Results of this study explored potential and cheaper options for sources of planting materials for tomato growers in the area with performance and quality comparable to existing check cultivar.
