Abstract:

Of all the abiotic stresses limiting crop productivity, drought is considered as the most important. Despite various research initiatives, drought continues to be a major challenge. To overcome this limitation and to improve crop productivity, it is important to improve the drought tolerance associated traits in cultivated plants. Twenty genotypes of tomato were evaluated in a Randomized Block Design (RBD) at the Department of Plant breeding and Genetics, College of Agriculture, Vellayani, during 2015-2017 to identify high yielding genotypes of tomato under water stress condition. Analysis of variance showed that significant variation was present in the germplasm for the characters studied. Accession A6 (Kottayam local) was identified superior in yield performance under water stress. The accession A6 (Kottayam local) also recorded the highest relative water content, stomatal frequency and proline content. Accumulation of proline in leaves was found to be an important water stress tolerance mechanism.


Keywords: Tomato, Water stress, Relative water content, Proline content, Stomatal frequency, Genetic parameters.
