Abstract: An experiment on comparison of fourteen accessions of Abelmoschus esculentus L. as poultry pigment in seed germination, yield (leaf, stem and seed) and nutritional values (leaf and stem) was conducted. The results showed: both seed germination and dry matter yield (leaf, stem) were significant difference among the fourteen accessions. The 021 and 007-1 were the highest (92.5%) in germination rate, and leaves of 004-2(4948 kg/hm2), stems of 018 (7103.4kg/hm2) yielded the highest. the 008 had the highest nutritional value. the 007-1 was the highest in seed yield, more than 3000kg/hm2. Being given a general consideration, the 018 was better than others as poultry pigment.
