Rice is cultivated on 24,000 ha,mostly under rainfed conditions, with an average production of approximately 1.1 t ha-1 in Balaghat District of Madhya Pradesh, India. The average annual rainfall in the district is 1,600 mm, with 70% occurring from mid-June to late September. Consequently, nearly 70% of the rice area under medium and low-lying conditions is transplanted. Being located near gall midge (Orseolia oryzae Wood-Mason)-prone areas such as Raipur and Sakoli, the rice crop in the district suffers almost every year from attacks from this pest. The state government of Madhya Pradesh had introduced gall midge-resistant varieties such as Asha, Surekha, and IR36. However, farmers stopped growing resistant varieties, except for IR36, after one or two cropping seasons because they did not meet their requirements. Consequently, susceptible varieties (e.g., Kranti, Kalture, MW10) possessing characteristics desired by farmers were adopted. In recent years, heavy gall midge attacks in the district compelled farmers to look for resistant varieties with the desired characteristics.
