摘要

Seed cost is a major input expense for the production of kabuli chickpea (Cicer arietinum L.) due to its large seed size. Use of small seeds could reduce production costs because a lower volume of seeds would be needed per unit area. This study determined the effects of seed size, and selective use of small seeds, year after year, on the field performance of kabuli chickpea in Swift Current, Saskatchewan from 2000 to 2003. Separated large (9.1–11.0 mm diameter) and small (8.1–9.0 mm) seeds of certified CDC Xena were compared with the original, unseparated seeds during the 4-yr study period. Also, small seeds separated from small-seeded previous crops and large seeds separated from large-seeded previous crops were compared with the respective generations of unseparated seeds. Year significantly affected plant biomass, seed yield, and the proportion of &= 9-mm-diameter seeds (9DSeeds) in the harvested seed lot, and crops grown from large and small seeds separated from the original seed lot (i.e., 1st year of separation) did not differ in a given year. The 2nd year of selection for small seeds affected seed yield and 9DSeeds, although the effect was minimal. With 3 consecutive years of selection, small seeds lowered seed yield by 23% and decreased9DSeeds by 10% compared with the unseparated seeds. Selective use of large seeds improved biomass, but did not increase seed yield or 9DSeeds compared with the unseparated seeds. Small seeds of a certified kabuli cultivar can be selectively used for up to 2 consecutive years before incurring a yield penalty, but the use of small seeds will decrease the percentage of large seeds in the harvested seed lot.
