In the overall performance, KNM 1638 recorded mean productivity of 7356 kg ha-1 in the eight years of trials with 12.8% increase over the check varieties. It has good grain, cooking and eating quality, and good marketing facility as quality-wise it recorded 63% head rice recovery and 21.47% amylose content with soft gel consistency and moderate gelatinization temperature. The rice variety, KNM 1638 is suitable for cultivation during kharif, late kharif and rabi seasons throughout Telangana State with higher yield, better pest and disease resistance and good cooking quality in comparison to the check varieties.
