A field experiment was conducted at Experimental farm, Department of Vegetable Research Centre, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during summer season, 2015 to find out the effect of weather parameters on YVMV incidence of okra varieties in summer season. The experiment was conducted in randomized block design with four replications and six varieties (V1- Parbhani Kranti, V2-Parbhani OK-1, V3-Arka Anamika, V4-Arka Abhay, V5-VRO-6 (Kashi Pragati) and V6-Pusa Sawani). The results from the experiment revealed that incidence of YVMV was initiated in March and reached maximum in May. The correlation studies revealed that maximum and minimum temperature showed highly significant correlation (p < 0.01) with YVMV incidence on different okra varieties. Relative humidity (maximum) was significantly negative correlated with disease incidence. Evaporation has shown significant correlation with disease incidence only on V2 (Parbhani OK-1). Wind velocity showed significant positive correlation (p < 0.05) with varieties (V1, V3, V4, V5) while varieties V2 and V6 were positively correlated. Hence, the variety Parbhani Kranti can be grown in summer season as it showed less YVMV incidence and recorded higher productivity over other varieties.
