Further Tests with Black Walnut Varieties

L. H. MACDANIELS _and_ J. E. WILDE, _Cornell University_

In 1937 the Northern Nut Growers Association committee on varieties and
judging standards proposed a tentative schedule for the judging and
evaluation of black walnut varieties(1). It was pointed out at that time
that for one reason or another none of the schedules which had been used
in judging walnuts were satisfactory and usable in giving an accurate
estimate of the cracking quality and value of a variety. It was
recognized also that the schedule proposed was only tentative and that
it would need to be modified in the ligh
