Abstract: Some 180 tomato accessions grown in Rajendranagar, Hyderabad, Andhra Pradesh, India, during 1997/98 were evaluated for various fruit physiological disorders. Approximately 34.4 and 25.56% of the accessions exhibited radial (cracks across the stem scar) and concentric (cracks around the stem scar) cracks, respectively. Both radial and concentric cracks were recorded for 13.33% of the accessions. Approximately 3.33% of the accessions had green back (presence of green parts in mature and ripening fruits), whereas 6.66% of the accessions showed fruit fasciation (adherence of two fruits to each other). Puffiness (partially filled fruits) was observed only in EC 163594 (0.56%).
