Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Ekse, Ali Osman
Abstract:: Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...

Time and duration of growth stages and subsequent grain yield in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Choi, Byung Han
Abstract:: The need to develop a shorter life cycle wheat cultivar which would be more adapted to multiple cropping systems prompted this study. Thus the following information was obtained. Greatest variations in developmental patterns were found in the stem elongation, booting, inflorescence emergence and anthesis for five winter and five spring...

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...

Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

Creator:: Tola, Jaime
Abstract:: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

Nature of inheritance, genotype-environment interaction and association of selected agronomic characters in crosses of winter X spring wheats (triticum aestivum L. em Thell)

Creator:: Brajcich, P.
Abstract:: This investigation was motivated by the apparent increase in genetic variability resulting from the systematic combining of gene pools represented by winter and spring types of wheats. It was the objective of this study to provide information regarding the nature of this genetic variability for nine agronomic characters in populations...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:: Baltazar, Baltazar
Abstract:: Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

Duration and rate of the grain filling period and subsequent grain yield in crosses between facultative and winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Mou, Beiquan
Abstract:: Concerns about the genetic control and environmental influence of various stages of development including the grain filling period, and the relationship between early maturity and grain yield prompted this study. The experimental material consisted of two facultative and two winter wheat cultivars. A dial!el cross, excluding reciprocals, was also developed...
