Resistance to Anthracnose Disease in Commercial Cultivars and Advanced Hybrids of Mango
Supriya Gupta, K.P. Singh and A.K. Singh

Abstract:
Mango (Mangifera indica L.) production is drastically reduced by Colletotrichum gleosporoides, is one of the most damaging pathogen causing mango anthracnose. In order to find sources of resistance to this disease, forty mango cultivars were screened under natural epiphytotic conditions in horticulture research centre at Pantnagar for the last two years (viz., 2013 and 2014). Grouping of cultivars for disease intensity, infection rate and AUDPC showed that 5% cultivars were resistant, 30% moderately resistant, 22.5% moderately susceptible and remaining 42.5% susceptible to highly susceptible. Nariayal and Chenna Swarnarekha exhibited the minimum infection rate (0.018, 0.036) and AUDPC (427.98, 476.75) resulting in 16.67 and 19.17% disease intensity. Nine were moderately susceptible while rest of the cultivars were either susceptible or highly susceptible. Bada Malda cultivar showed the highest AUDPC (3294.14%) and the maximum percent disease intensity (92.34%). Other cultivars, however, exhibited intermediate range of infection rate and AUDPC. The disease progress curves clearly depicted the levels of disease in each cultivars during the observational periods. These resistant to moderately resistant mango cultivars can be used in breeding programme for developing varieties adapted to the region against anthracnose blight.
