Abstract The present study was undertaken with 30 aromatic rice genotypes grown in four environments (24 June and 14 July sown for two years; kharif 2008 and 2009) in randomized block design following standard package of practices for aromatic rice at Rice research Field, RAU, Pusa, Bihar. Observations were recorded on quantitative and quality traits. It was observed that among the different dates of sowing, E3 (24 June, kharif 2009) gave the highest grain yield followed by E1 (24 June, kharif 2008). Genotype × environment interaction was observed to be significant for most of the characters except for panicle length, effective tillers per plant, spikelets per panicle, filled grain per panicle, leaf area index, specific leaf weight and gelatinization temperature under study. For grain yield, Sanwal Basmati was observed as above average stable, whereas Pusa Sugandh-3 was the average stable and Jasmine and NDR 9542 were below average stable genotypes. These stable genotypes, namely, Sanwal Basmati, Pusa Sugandh-3, Jasmine and NDR 9542 have reflected stability for component traits. Top Keywords Aromatic, Oryza sativa L, Rice, Stability. Top |
