Noteworthy new items on this list include a series of L . hirsutum introgression lines (developed by A . Monforte and S . D . Tanksley), a group of S . lycopersicoides monosomic alien addition lines in L . esculentum (R . T . Chetelat), new marker gene combinations (M . Koornneef, H . Laterrot, J . Maxon Smith, C . M . Rick) and additional cultivars (R . Gardner, J . Scott) . We attempt to maintain all listed accessions in adequate supply for distribution . However, some stocks, such as certain multigenic combinations, aneuploids, or prebreds, are weak and require special cultural care; consequently, seed supplies may at times be too low to permit distribution .   Names and phenotypic classes of individual mutations are given in the last Monogenic Stock List, issued in TGC 49; other pertinent data are presented in previous TGC Reports, as cited below .   Additional information concerning the origin of these accessions, recommendations for growing and reproducing them, and other aspects of these stocks will be gladly furnished on request . Previous stock lists and information such as phenotypic descriptions, collection notes, images of mutants, etc . , can be obtained from our website (http://tgrc . ucdavis . edu ) .    Accession Categories I .
