Climatic change: a review of causes
Autor: J. B. Harrington
Publikováno v: Canadian Journal of Forest Research. 17:1313-1339
The earth's climate is constantly changing. Climatic change is effected by many factors: the influence of continental drift, variations in solar intensity, volcanism, the impact of meteors and comets, changes in the earth's orbital parameters, ice ac

THE INHERITANCE OF REACTION TO BLACK STEM RUST OF WHEAT IN A DICOCCUM × VULGARE CROSS
Autor: J. B. Harrington, W. K. Smith
Publikováno v: Canadian Journal of Research. 1:163-188
A genetical study of resistance of wheat to black stem rust, and a plant breeding attack on the rust problem are described. A large F2population of the cross Vernal (T. dicoccum) × Marquis (T. vulgare) was grown under severe natural epidemic conditi

YIELDING CAPACITY OF WHEAT CROSSES AS INDICATED BY BULK HYBRID TESTS
Autor: J. B. Harrington
Publikováno v: Canadian Journal of Research. :578-584
In order to determine readily the usefulness of heterosis as an indicator of the yielding capacity of cereal crosses, replicated half rod row yield trials were made with bulk unselected seed of ten wheat crosses in F2 and of six in F3. The practical

PREDICTING THE VALUE OF A CROSS FROM AN F2 ANALYSIS
Autor: J. B. Harrington
Publikováno v: Canadian Journal of Research. 6:21-37
The results of extensive breeding work with the cross Marquillo × Marquis were compared with both the original expectation and the expectation calculated from a study of random F2 populations. The cross was made for the purpose of combining the rust

THE RELATIONSHIP BETWEEN ENDOSPERM DEVELOPMENT AND MORPHOLOGIC CHARACTERS IN THE F2 GENERATION OF A T. DICOCCUM × T. VULGARE CROSS
Autor: J. B. Harrington
Publikováno v: Canadian Journal of Research. 5:208-218
The relationship between the degree of plumpness of F2 seeds and the type of the resulting F2 plants was studied in the cross Vernal (T. dicoccum) × Marquis (T. vulgare). A random sample of F2 seeds was divided into three classes based upon kernel p

THE RELATIONSHIP BETWEEN MORPHOLOGIC CHARACTERS AND RUST RESISTANCE IN A CROSS BETWEEN EMMER, (TRITICUM DICOCCUM) AND COMMON WHEAT, (TRITICUM VULGARE)
Autor: J. B. Harrington
Publikováno v: Canadian Journal of Research. 2:295-311
A study of morphologic character in relation to field resistance to black stem rust of wheat (Puccinia graminis tritici, Erikss. & Henn) was made on the cross Vernal (Triticum dicoccum, Schubl.) × Marquis (T. vulgare, Host.). Fifteen morphologic cha
