| dc.description.abstract | The laboratory and field experiments were conducted, during kharif, 2010 for identification of tomato genotypes through morphological, chemical and molecular markers and influence of organic manures on seed yield and seed quality in tomato cv. DMT-2 at Seed Quality and Research Laboratory of National Seed Project, and main agricultural research station UAS, Dharwad respectively. Twelve tomato genotypes were grouped into 18 groups based on the seed morphological characters such as seedling leaf color, days to maturity, foliage density, leaf type, exterior color of immature fruit, fruit shape fruit size, exterior color of mature fruit, from pedicel, fruit shoulder shape, skin color ripe fruit, flesh color intensity, fruit cross sectional shape, number of locules, shape pistil scar and fruit blossom end shape. The chemical tests viz., Phenol, modified phenol, Peroxidase, NaOH and KOH tests disabled the grouping of tomato genotypes based on the color response. Genotypes used in this investigation did not exhibit change in seed coat color as well as solution. Based on the seedling growth response to GA3, genotypes were grouped as low, moderate and high response and based on 2,4-D genotypes were grouped as least, moderate and highly affected. Random amplified polymorphic DNA profile for all 12 genotypes was generated with 20 random decamer primers. The highest molecular diversity was observed between the genotypes DMT-3 and DMT-6 and High similarity with Sij 0.99 was observed between genotypes DMT-5 and DM-4. The field experiment consisted of 11 treatments involving different organic manures. Among the treatments recommended dose of fertilizer (T11) recorded significantly superior values over other treatments with respect to growth, yield and seed quality parameters. | en_US |
