incompatibility in tomatoes EB. F, Paddoc's Expt Sta

The genetics of wide species hybrids in the tomato group is of consic-
erable practical importance in the development of new disease-resistant vari-
eties, In addition, the unique chromosome morphological differentiation of
this group deserves to be further exploited in cytogenetic analysis, The pro-
posal does appear, therefore, to elate to problems of a fundamental nature,
However, from a fundamental basis there seems to be very little that is really
new in the indicated research, The patterns of embryo to endosperm relation=
ships have, as the authors indicate, been rather thoroughly worked out in this

group and it is doubtful whether lip service to the term allomitry iexto add" tre or

very much to what has already beon developed, The technique of genome @nely-
sis by means of trisomic is of course an old story and the productivity of

the authors does not suggest a very Likely and rapid development of their
subject. For this reason I feel that the authors are not likely to make quite
as much out of the mroblem as there might be there, but the proposal is nonee
theless meritorious, For the same reasons, however, a fiveeyear grant would
not appear to be justified and this should be cut to about three, In addition,
the over-all proposal seems to be somewhat ambitious in relation to the funda
mentel value o% the observations thet can be anticipated,
