Notes, scoring (yield, etc.): population size and selection experiment. Contains typescript report on earlier stages of experiment (1951).

Scoring for yield of crosses. Probably a continuation of AJ Bateman's study of heterosis and inbreeding depression in brassica (JIHI Annual Report 1952, 1955).

Notes, experimental results, draft papers etc. relating to Peter Matthews work in the Applied Genetics Department at JI, 1958-1988, initially on cherry breeding and Pseudomonas morsprunorum, and later on genetics and pathogens of Pisum. Also records of work on resistance to Fusarium wilt in carnation.

Register of descriptions of cherry varieties, with notes on origin, character, genetics, and references. Contains separate registers of similar notes on JI selections (in range 4813-14716), also with notes on NFT status and reference to slide collection, and on sources of genetic variation (separate sections on x-ray mutations and self-fertiles). Also lists of varieties with particular characters, including those carrying genetic traits such as dwarf.

Extensive notes and experimental results: cherry stone accessions and sowings, test inoculations using different strains of Pseudomonas, leaf washes, early work on bacteriophages and bacteriocins of Pseudomonas morsprunorum.

Notes on experimental procedures, etc. and tables of scoring of selected inoculated varieties (including 'Merton' cherries) for infection/ resistance.

Table of major varieties used in breeding, with genetic information (s-alleles, flesh colour, albino and dwarf characters) and notes on susceptibility to bacterial canker.

Isolation of Pseudomonas morsprunorum, Pseudomonas syringae. Includes photographs
