‘Mountain Merit’ is a large-fruited, determinate, fresh-market F 1 hybrid tomato ( Solanum lycopersicum L.) resistant to late blight [ Phytophthora infestans (Montagne, Bary)]; verticillium wilt ( Verticillium dahliae ); fusarium wilt
Abstract
Fruit of 2 cherry tomato (Lycopersicon esculentum var. cerasiforme Alef.) cultivars [‘Large Red Cherry’ (‘LRC’) and ‘Small Fry’ (‘SF’)] and 2 large-fruited tomato (Lycopersicon esculentum Mill.) cultivars (‘Duke’ and ‘Sunny’) were harvested green, ripened at 23°C, and analyzed for sugars and organic acids 6 days after breaker stage. Both fructose and glucose concentration decreased in ‘LRC’ and ‘SF’ fruit with less-mature harvested fruit. Maturity at harvest had no effect on the concentration of either sugar in ‘Duke’ or ‘Sunny’ fruit. ‘LRC’ had the highest fructose and glucose concentration among cultivars. Increased citric acid concentration was found with less-mature harvested fruit, except in ‘LRC’. Malic acid concentration within cultivars was similar in the fruit harvested more mature, but decreased with less-mature fruit in ‘Duke’ and ‘Sunny’. ‘LRC’ and ‘SF’ fruit had more citric and malic acid than ‘Duke’ or ‘Sunny’. Cherry tomato cultivars had a higher percentage of locular tissue than the large-fruited cultivars.
‘Mountain Lion’ is a large-fruited, fresh-market hybrid tomato ( Solanum lycopersicum L.) developed by crossing NC 1CS × NC 2rinEC. It is resistant to verticillium wilt ( Verticillium dahliae Kleb) (race 1), fusarium wilt [ Fusarium oxysporum f
Abstract
The variability, mode of inheritance, and gene action for soluble solids was studied in a cross of 2 divergent lines, Mo. Accession 223, a selection of PI 272689, and 1-417-1. About 3 gene pairs were indicated to control soluble solids. Additive gene action accounted for a heritability of about 35%. In the broad sense, heritability was about 59%, suggesting that non-additive genetic variance was about 25%. Evidence for dominance and for epistatic interactions of genes appeared to be lacking.
. Tomato fruit were harvested twice (10 and 12 WAT) in the mature green stage and were graded following current market standards as extra-large and marketable fruit of all categories ( Sargent et al., 2005 ). Fruit yield from the first harvest (10 WAT) were
