Stigma Receptivity Test in Diverse Species of Tomato

The present experiment on tomato comprised of 17 g enotypes belonging to ten different species. The re search was carried out at “Research Centre for Distant Hybrid ization in Field and Fruit Crops, Dept. of Agricultural Biotechnology, Anand Agricultural University, Anand du ring 2016-2017”. Stigma receptivity being one of th e important traits influencing the rate of pollination and succ essful fertilization was under taken in the present s udy. The observations were recorded from tomato species on st igma receptivity by using Hydrogen peroxide. The st igma was found receptive before 12 hrs. of an thesis and may continue upto withering stage of flower, which was the common pattern observed in all the species. Stigma became fully receptive after opening of flower bud. But, in case of accession LA 1777 (S. habrochaites), the stigma did not become receptive at bud stage, while stigma of LA 2157 (S. arcanum) and LA 2819 (S. lycopersicum) showed receptivity from bu d stage.
