Abstract/ Executive Summary:

This experiment was conducted in JAES, Manikgonj. Seeds of 100 C.olitorius accessions along with var OM-1 and O-9897 as control was sown two times in the field in 3m single rows The dagte of 1st and 2nd sowings were 1st and 15th March, 1001 respectively to screen C. olitorius germ plasm for short-day tolerance. In the 1st sowing, all the accessions and var O-4 were flowered within 38 days after sowing (DAS) except var. O-9897. But in the 2nd sowing the flowering pattern was little be different from the 1st one. Here 89 accessions including var. 0-4 were flowered within 38 DAS, 6 accessions were flowered within 48 DAS and only 3 accessions were flowered at 72 DAS but our short-day tolerant var . O-9897 was flowered after 145 DAS (Table Physio-2). So in this screening program actually no accessions were found better tolerant than our existing var. O-9897.

Achievement/Findings:

In the 1st sowing, all the accessions and var O-4 were flowered within 38 days after sowing (DAS) except var. O-9897. But in the 2nd sowing the flowering pattern was little be different from the 1st one. Here 89 accessions including var. 0-4 were flowered within 38 DAS, 6 accessions were flowered within 48 DAS and only 3 accessions were flowered at 72 DAS but our short-day tolerant var . O-9897 was flowered after 145 DAS (Table Physio-2). So in this screening program actually no accessions were found better tolerant than our existing var. O-9897.
