The genetic base was defined as the ancestral pool from which crop varieties were derived, and was used to characterize genetic diversity in crop breeding. Number of primary parents used between 1913 and 2002 in Korean soybean breeding programs was 65 and

Chomsky (2000) proposes that the operation Attract-F of Chomsky (1995) be replaced by the operation Agree, in which there is, in principle, no movement at all. In the Agree theory, agreement between a Probe P and its Goal G can lead to feature checking in situ. Lasnik (2002), however, argues that feature movement (or attract) is to be preferred to agreement at a distance, presenting three pieces of evidence: pseudo-gapping, sluicing, and remnant movement. The purpose of this article is to show that the agreement-at-a-distance theory of Chomsky (2000) can still be maintained if we adopt Pesetsky and Torrego`s (2001) conception of the EPP property as a "subfeature of a feature." Furthermore, if we assume Boeckx and Stjepanovic´`s (2001) claim that head movement is a PF phenomenon, the persuasiveness of Lasnik`s (2002) argument becomes even weaker. Following Chomsky`s (2001b) assumption that internal Merge can apply either before or after Spell-Out, I have demonstrated that even the remnant movement phenomenon, the most powerful piece of evidence for Lasnik`s (2002) argument, can naturally be accounted for with the feature checking in situ of the Agree theory.
