Abstract
In Assam, boro rice is generally cultivated during November/December to May/June. It is grown in low-lying, water-logged areas with high residual moisture. One of the major problems faced by rice cultivation in Assam is flood leading to large scale destruction of the crop during monsoon. Cultivation of boro rice during the dry season in this area is preferable to meet the growing requirement of food by the increasing population. Therefore, a study was undertaken to evaluate the morphometric characteristics of 46 boro rice varieties collected from different agro-climatic zones of Assam. The result of this investigation revealed significant values of different morphometric parameters of the boro varieties which signify the good quality of rice seeds and kernels. A positive correlation of seed size was found at 0.05 level with seed length (r=0.591*), seed width (r = 0.671*) and seed thickness (r = 0.743*). The kernel thickness and kernel length to width ratio (r=0.619*) also showed a significant positive correlation at P<0.05 level. Thus, characterization of boro rice is a necessary step for future breeding programmes along with providing breeders with sufficient information in selecting relevant traits.
