Verticillium wilt, caused by the fungus, Verticillium albo-atrum, is a destructive disease of tomatoes in many areas. Due to the seriousness of this problem, Cannon and Waddoups (1) have developed resistance to this disease in some commercial varieties grown in Utah.

This study is concerned with the meiotic chromosome behavior and the comparative morphology of a sterile grass of doubtless hybrid origin. Though possessing morphological characters which place it in the Hordeae tribe, the unusual combination of morphological characteristics made it difficult to assign it to a particular genus. Its spikelets, usually solitary, placed flatwise at the nodes, on opposite sides of the rachis are typical of Agropyron species: while the bifid plumes, spreading awns and a tardily disarticulating rachis, are characters which suggest Sitanion species.

False Smut Of Buffalograss, John L. Weihing
Nebraska Agricultural Experiment Station: Historical Research Bulletins
False smut of buffalograss, Buchloe dactyloides (Nutt.) Engelm., caused by Cercospora seminalis Ell. & Ev. is a disease that destroys the unfertilized ovary. The disease was first reported by J. B. Ellis and B. M. Everhart in 1888. They gave only a brief description of the disease and named the causal fungus Cercospora seminalis. There are no etiological studies of false smut recorded in the literature. The origin of the term "false smut" is unknown to the author, but it so descriptively fits the general appearances of the disease that one readily understands its usage. The following studies were …

The orchids known today make up one of the largest Angiospermous families in the world. Recent estimates place the number of genera at about 450 which estimates between 10,000 and 15,000 species (some authorities go as high as 20,000). They are without doubt one of the most highly specialized groups of green plants. Botanically the flowers are of more than passing interest for they deviate so distinctly from the norm of the Monocots. They are the possessors of a number of unique structures that are found in no other family of flowering plants.

The occurrence of hybrids, both interspecific and intergeneric, is frequent in the Gramineae generally (Stebbins, 1949), and is especially common in the tribe Hordeae of which both A. trachycaulum and H. jubatum are members. Intergeneric hybrids in this tribe have been studied by Stebbins et al. (1946a, and 1946b), Stebbins and Walters (1949), and Stebbins and Singh (1950) in an effort to determine true phylogenetic relationships on which to base a taxonomic classification, and results of these studies have indicated that the current taxonomic treatment of this tribe is highly artificial. Attempts to produce a perennial wheat and improve …
