Abstract: Development of roots from the stem cuttings without auxin treatment indicates presence of indigenous/native auxin in plants. In the present investigation variation in indigenous auxin response of tomato genotypes was studied by dipping the stem cuttings of 25-30 days old seedlings in distilled water. Roots were found to develop from the cuttings and observations were recorded on length of the longest root, number of roots per cuttings, fresh root weight of stem cuttings and frequency of rooted cuttings on 10th day. Root length of the genotypes varied from 0.0 to 5.50 cm with an average of 2.56 cm. Number of roots produced per cuttings varied from 0.0 to 50.5; fresh root weight ranged from 0.0 to 0.152 gram and frequency of rooted cuttings varied from 0.0 to 0.70. Indigenous auxin response of tomato genotypes was expressed in terms of auxin induced rooting index. The yielding ability of the tomato genotypes was evaluated in a randomised block design. High yielding tomato genotypes showed high rooting index. The correlation between auxin induced rooting index and yield was positive (0.250). This indicated that indigenous auxin response could be used as an indicator for preliminary selection of high yielding genotypes.
