Abstract

Information on genetic diversity with respect to various agro-morphological traits and eating and cooking quality traits plays a key role in the improvement of rice (Oryza sativa L.). With this aim, we have characterized a set of 98 indigenous aromatic rice germplasm accessions for four agro-morphological, two physical and two physico-chemical traits. Significant variation was observed among the cultivars for all the traits. Correlation analysis showed negative correlation of DFF with KLBC (r= -0.29; p=0.022) and kernel L/W ratio (r= -0.25; p=0.003), while PL was significantly and positively correlated with KLBC (r=0.38; p=0.000) and kernel L/W ratio (r=0.43; p=0.0649). KLBC showed highly significant positive correlation with GC (r=0.22; p=0.614) while between AAC and GC a significant negative correlation was observed (r= -0.38; p=0.000).
