Evaluation of sesame genotypes for tolerance to waterlogging and development of mitigation strategies

Abstract

The present study was initiated to identify constraints of sesame farmers in Kerala, to screen sesame genotypes for tolerance to waterlogging, identification of suitable ameliorative treatment for waterproofing sesame, molecular characterization of sesame genotypes with genes and markers reported for waterlogging tolerance and screening for drought tolerance. Sesame growing farmers were surveyed in three districts of Kerala viz., Alappuzha, Kollam and Thrissur during 2018. Data was analyzed using Garrett ranking technique. Identified constraints were high labour cost, excessive rain fall, drought, weed infestation, unavailability of labour, pest and disease, marketing problem, problems for transportation, drying and threshing, and storage problems in decreasing order of their Garrett rank.
