Abstract EN
Using the present technique, clear prometaphase figures have been obtained from the primary root tips of "Khudari" date palm (Phoenix ductylifcra L.) seed lings.
The diploid number of chromosomes confirmed the previously reported 2/1 = 36.
Colchicine treatment for only one hour showed more accurate measurements of total chromosome length and arm roué than three hours.
KaryologrcaL analysis of the largest nine pairs of chromosomes revealed that pairs I, 2 and 4 arc submetaeentrie.
pair 3 is mctaccntric , pairs 6 and 7 are subtcloccntric, while pairs.
5, 8 and 9 are-rocentric.
The discrcpcncy between these results and those previously reported was attributed to the duration of colchicine treatment.
Because of the consistency of results in all preparations, none of the largest nine chromosome pairs was considered to have a role in sex determi~ation in "Khudari" date palm.
