An investigation of the locality effect on seed wheat : Yield studies on eighty-one lines of cross 7 wheat seed : Thesis submitted for M.Agr.Sc. [Master of Agricultural Science] and Honours, 1949, University of New Zealand

Abstract

With many arable crops it has been observed by practical agriculturalists that seed from a different locality sometimes produces a more vigorous crop. Seed from certain districts is often sown in preference to local seed. The common explanation is that some difference in the environmental conditions between the two districts causes the seed transferred to the new district to yield better than locally grown seed. This effect is temporary and is seldom noticed after the first few generations.
