Abstract:
Asian soybean rust caused by Phakospora pachyrhizi Syd. is one of the most important constraints to soybean production worldwide. Though there are many effective management practices are there to manage this disease, breeding for resistance is the most effective method. A first step in breeding for resistance will be screening and identification of stable resistant germplasm. Hence, an attempt was made to identify the new sources by screening 144 exotic germplasm lines along with resistant and susceptible checks at University of Agricultural Sciences, Dharwad during kharif 2015. Among them, EC 242104 recorded disease grade 1(8.89%) with highly resistant reaction. Further, evaluation of 22 selected lines with different resistant reaction, under natural epiphytotic condition at two hotspots for rust viz., Dharwad and Ugarkhurd during kharif 2016 lead to confirmation of highly resistant reaction of EC 242104 with grade 1. EC 242104 would serve as a source of resistant genes for incorporation into high yielding and adapted cultivars in crop improvement programmes.
