| dc.description.abstract | Tomato (Solanum lycopersicum L.) is an important source of several minerals and vitamins. Exhibits wide degree of variability with respect to growth habit, fruit size, fruit shape, fruit color and yield per plant etc., Twenty exotic and indigenous accessions of tomato were screened for variability in terms of morphological, biochemical and molecular diversity. Fifteen were indeterminate type and five were determinate type. The accessions with best morphological characters identified were viz., EC-620545 (higher fruit weight-162.00 g and high fruit yield-8.24 kg/plant), EC-16786 (higher fruits/cluster-8), EC-159053(high lycopene content-10.12 mg/100g), EC-168283 (high ascorbic acid content-18.07 mg/100g) and EC-151568 (high TSS-8.08 0Brix). High GCV(21.18 to 40.32)and PCV(25.44 to 41.08) values were recorded for plant height, fruit firmness, total solids, TSS, fruit length, fruit width, fruit weight, number of clusters per plant, number of fruits per cluster and yield. Very high GCV and PCV values were recorded for lycopene content (71.00; 71.23) and ascorbic acid content (59.10; 59.31).The heritability estimate were very high for plant height, number of days from flowering to fruit set, fruit pH, fruit firmness, total solids, lycopene content, TSS, ascorbic acid, fruit length, fruit width, fruit weight, number of clusters per plant, number of fruits per cluster and yield per plant. The molecular diversity was assessed using thirty SSR markers, out of which fifteen were polymorphic and shown highest similarity matrix between EC-165690, EC-168283, EC-249514, EC- EC-249515, EC-320574-1, EC-362944 and EC-151568. Hence these markers can be used to measure the genetic relation between the accessions during crop improvement. | en_US |
