Traditional basmati rices have tall plants, droopy leaves, high lodging tendency, relatively low grain weight and low grain number. Inspite of poor yield, their unique cooking quality fetches the highest premium in the national and international markets. Karnal Local, Basmati 370, and Type 3 are the most widely cultivated varieties. However, Karnal Local's high kernel length and higher length: breath ratio was preferred in the market. After two decades of intensive convergent breeding with rigorous screening and selection, IARI has developed three promising basmati lines: Pusa 367-152, Pusa 615-140-10-1, and Pusa 751-1-2. Pusa 367-152 has excellent plant type with stiff stem and dark green erect leaves. It has desirable cooking qualities; however, grain shattering, late maturity and mild aroma are drawbacks. Pusa 615-140-10-1 has good plant type and all important basmati components, but with relatively higher amylose content. Pusa 751-1-2 is much superior to traditional basmati in cooking quality and aroma but does not yield well because of low grain number and relatively moderate tillering. Among them, Pusa 615-140-10-1 (IET 10364) has been selected for farm trials. All three lines may be useful as donors in the basmati rice improvement program.
