CER and leaf characteristics of four tall fescue (Festuca arundinacea Schreb.) selections differing in forage yield

Creator:: Cohen, Cynthia Joy
Abstract:: Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...

Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...

Association between length of grain filling period and grain yield in two wheat populations (Triticum aestivum L. em Thell.)

Creator:: Min, Hwang Kee
Abstract:: The objective of this study was to determine interrelationships among agronomic traits in early and late maturing populations. Two populations were obtained from the crosses, Roussalka/Tesopaco 76 and Yamhill/Aspen. Seeds were space planted with split plot design and nine agronomic traits were observed. In comparative studies between early and late...

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...

Assay of the trypsin inhibitor activity in seeds of triticale

Creator:: Yao, Tsui-Li
Abstract:: Triticale, a newly man-made cereal from a wheat-rye cross offers a unique food and feed potential because of its higher protein content with nutritionally balanced amino acid composition as compared to other cereal grains. However, some cereal proteins such as trypsin inhibitors, present in triticale and rye, can affect the...

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...

Durum wheat quality and its relation to electrophoretic banding patterns

Creator:: Encinas-Mungarro, Andrés
Abstract:: Physical properties of gluten and pigment content are of primary importance in determining quality in durum wheat (Triticum turqidum L. var. durum). The objective of this investigation was to evaluate the contribution of different -y-gliadin protein subunits in durum wheat pasta quality as measured by the sodium dodecyl sulphate microsedimentation...

Modeling phyllochron in wheat and barley

Creator:: Cao, Weixing
Abstract:: An understanding of the effect of environment on phyllochron (degree-days between two successive leaves) is necessary to model cereal crop canopy growth. This study was designed to investigate the relationships of phyllochron to temperatures and daylengths in winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). A series...
