Abstract
The standard germination test serves as a measure of seed quality, utilized to forecast field emergence under nearly optimal conditions. Healthy seeds result in robust seedlings, ultimately contributing to improved crop yields. Two germination experiments were conducted at the same time in laboratory and open field conditions in December 2025 following a similar procedure to study the seed performance of four sugar beet genotypes. Four genotypes were namely, Danicia, Allanya, Serenada and Gregoria, collected from the Bangladesh Sugarcrop Research Institute (BSRI). Seeds were used to determine viability percentage, germination percentage and vigor based on seedling length, seedling fresh weight and germination speed index. Significant variation was observed in the studied parameters of sugarbeet genotypes. Higher to lower values of viability, germination, seedling length, seedling fresh weight and germination speed index were found in the Allanya, Gregoria, Danicia and Serenada genotype seeds, respectively. The germination results (>80%) indicated that the Allanya and Gregoria genotypes seeds of sugarbeet, respectively, were better under laboratory and open-field conditions.
