Summary
Seed production of leek is very important thing in increasing of the surfaces under the leek, and in bigger using of leek in nutrition. If we recognize that seed of leek is so small, that it has hard and rugged percarp, that development is non uniform and slow, that it has small germination (approximately 70%), and moreover that it lose germination very fast (after 1-2 years). Everything, mention before, has influence on problems related to seed production of leek. In agro ecological conditions of Kosmet is possible to organize very successful production of leek seed by leaker (two years, period of development) with acquirements of high yield (more than 1000 kg). In exploration we used old autochtonic cultivar of leek “Prizrenski kamus”. With mass of mother plant in 30-40 g with plant spacing about 100.000 plant per hectar we have reach yield of 795kg of seed. Mother plant with mass of 50-70 g with same number of plant spacing giving yield of 1065 kg/ha and the biggest one with mass of 80-100 g giving yield of 1190 kg/ha. Mother plant of leek almost always have only one bloom. Number of fruit in bloom in average, independence of mass of mother plant is around 939-1058. Number of seed per fruit in average is 3,9-4,1, and average weight of seed per bloom is 7,9-11,9 g. Mass of mother plant had no influence on quality of seed. Seed of leek has very good germination, in average 92% with absolute mass from 2,9 to 3,4. For recommendation is using of mother plants with middle weight becouse we obtain partly saving in seedling material and posibility of storage bigger number of mother plants in relation with surface of storage space during the winter.
