Results of the third International Spring Wheat Yield Nursery (ISWYN), 1966-1967
Fifty wheat vanettes representative of the major spring types were tested in the Third International Spring Wheat Yield Nursery ( ISWYN). Results were obtained from 62 locations throughout the spring wheat regions of the ...
A survey on stem rust resistance in the USDA world durum collection and in CIMMYT durum breeding lines
Utilizing the stem rust races with known pathogenicity genes, 349 varieties of durums have been screened. These varieties were selected from over 3,000 of the USDA World Durum Collection on basis of their field reaction ...
Annual report CIMMYT-I.D.G.C. 1975-1976 Algeria
(IDGC; CIMMYT, 1977)
The 1975-76 crop season was marked as the best cereal production year in Algeria since 1909 (the date from which data is kept). The rain distribution in almost all the regions was excellent from seeding to mid dough stage, ...
Annual report CIMMYT-I.D.G.C. 1976-1977 Algeria
The season of 1976-77 started with excellent prospects for another record crop for Algeria and ended up as one of the worst. Preseeding rainfall was excellent and at times too much in the east and this hindered proper land ...
Results of the fourth International Spring Wheat Yield Nursery, 1967-1968
Fifty wheat vanetles representative of the major spring types were tested in the Fourth International Spring Wheat Yield Nursery ( ISWYN). Results were obtained from 63 locations throughout the spring wheat regions of the ...
Triticale breeding and research at CIMMYT: a progress report
Triticale has created considerable discussion and controversy during the past few years. It has been promoted extensively in North America as a miracle crop, the answer tc growing protein deficits. Its failure to live up ...
Treatment design for fertilizer use experimentation
Ideally the experimenter would like to use treatment design to minimize both variance and bias problems in estimating yield from fertilizer application. Selecting a treatment design for variance considerations will not ...
Progress in developing triticale as an economic crop
This report summarizes the progress made and some of the problems encountered in the Triticale program at CIMMYT during the past year and a supplement to the reports prepared in 1968 and 1969. Since copies of the previous ...
Epidemiology of wheat rusts in the western hemisphere
Shortly after the turn of the century, devastating wheat rust epidemics in the Great Plains of North America (Northern Mexico, the Plains of the U.S.A. and the Prairie Provinces of Canada), prompted the study of physiologic ...
A survey on leaf rust resistance in the USDA World Durum Collection
Leaf rust of wheat, Puccinia recondita rob. ex Desm., is a major disease of wheat in many areas of the world. Samborski and Peturson (1960) reported reduction in yield of 58 percent at Winnipeg, Canada. Phipps (1938) ...
