Abstract:
Performance of forty genotypes comprising nineteen land races, one local check variety (Acharmati) and six high yielding varieties, twelve popular aromatic rice cultivars and two advanced breeding lines were evaluated to determine character association, variability and diversity for grain yield, yield components and aroma level under irrigated and non-irrigated conditions at RRTTS, Bhawanipatna, Odisha. High values of phenotypic coefficient of variance (PCV), genotypic coefficient of variance (GCV), high heritability (h2) and genetic advance (GA) were recorded for aroma level, grains per panicle and thousand grain weight. Significant positive correlation for panicles per plant (r =.603) and negative correlation for aroma level (r = -.370) was observed with yield. All the genotypes were grouped into 11 clusters. Most of the indigenous aromatic rice cultivars were found in Cluster I and others distributed in cluster IV, cluster V, cluster VII and cluster XI. Cluster II consisted of basmati types and cluster III comprised HYV. Aromatic Test (sensory test) using 1.7% KOH solution was done for rapid evaluation of aroma level of the genotypes. The present study revealed that the indigenous aromatic rice cultivars like Gangaballi, Khosakani, Neelabati, with high aroma level, Dubraj and Dhanaprasad with faint aroma were superior genotypes of their respective clusters under both irrigated and non-irrigated conditions. Crossing between superior genotypes of diverse cluster pairs may provide desirable transgressive segregants for developing high yielding varieties of aromatic rice and can be used as potential breeding materials for improvement of aromatic land races.
