Abstract: The Himalayan mountain range has significant bearing on the climate of India, as its towering height created a vast rain shadow zone in the north. Among the cold arid parts of India, Ladakh in Jammu & Kashmir is one of the highest (2900m to 5900m asl) and coldest. Leh and Kargil are two districts, which jointly form Ladakh region, the principal cold desert of India. Leh with an area of 45,110 sq km is the largest district in the country located in an altitudinal range from 2900 to 5900 m above mean sea level. Being cold arid region, the temperature ranges between -35°C in winter to +35°C in summer. In general, area has short mild summer to long cold winter. An experiment was conducted to identify promising accessions suited for cultivation under cold arid conditions of Leh, Ladakh. Twenty five accessions of French bean were screened for resistance to angular leaf spot disease during the spring seasons of 2018 in the Experimental field of High Mountain Arid Agriculture Research Institute (HMAARI) Leh, Ladakh, Sheri Kashmir University of Agricultural Sciences and Technology of Kashmir. The study revealed that under natural epiphytotic conditions none of the accessions was resistant in reaction. Seven accessions viz., Acc-252, WB-185, Acc-811, Acc-1643, Acc-4564, WB-22 and Acc-1692 were moderately susceptible. The other eight accessions viz., WB-1247, Local (Ladakh), Acc-966, Acc-1129, Acc-662, Acc-719, WB-216 and SKUAWB-5001 were susceptible in reaction. All other accessions viz., Acc-1492, WB-956, Acc-1690, Anupama, WB-275, Acc-1144, Acc-335, Acc-21529, WB-6 and SKUAWB-5000 exhibited highly susceptible reaction.
