Expression Of Susceptibility To Fusarium Head Blight And Grain Mold In A1 And A2 Cytoplasms Of Sorghum Bicolor, James P. Stack, Jeffrey F. Pedersen

West Central Research and Extension Center, North Platte

Panicle diseases are among the major constraints to sorghum (Sorghum bicolor) production in the northern Great Plains; host plant resistance is the primary management option. However, essentially all commercial sorghum hybrids contain A₁ cytoplasm, which raises the concern about increased disease risk as a result of cytoplasmic genetic uniformity. To determine the influence of cytoplasmic background on the expression of susceptibility to panicle diseases, F₁ hybrids with four nuclear genotypes in each of two cytoplasms (A₁ and A₂) were planted in three environmentally diverse geographic locations in Nebraska. Fusarium head blight ranged in …

Dalea Purpurea 'Stephanie', Dale T. Lindgren, Daniel Schaaf

West Central Research and Extension Center, North Platte

Dalea L. (prairie-clover) is a large genus of the western hemisphere consisting of herbaceous and shrubby plants (Great Plains Flora Association, 1986). Barneby (1977) lists over 160 species that range from the Canadian prairies into South America. The forage value of daleas for livestock is well known. Ornamentally, daleas are showy plants, desirable for their foliage as well as for their delicate flowers. Their value as a legume can also contribute to sustainable landscapes.

Dalea purpurea Vent., formerly designated as Petalostemon purpureus (Vent.) Rydb., and sometimes listed as Dalea purpureum is found growing from the Canadian prairie provinces to Texas …

Dalea Villosa ‘Sandhills Satin, Dale T. Lindgren, Daniel Schaaf, James H. Locklear

West Central Research and Extension Center, North Platte

Daleas (prairie-clovers) are annual or perennial, warm season legumes found from southern Canada to South America (Barneby, 1977). They are an important group of legumes in native grasslands of the Great Plains. The genus name Dalea L. is in honor of Samuel Dale, an English botanist (1659–1739). Until recently, these plants were classified in the genus Petalostemon Michx. (Weber, 1990). The prairie-clovers have potential as attractive garden ornamental plants in addition to their importance as constituents of prairies and pastures. They have uses, along with other native species, for beautification of roadsides, rest areas, parks, and recreation areas, and for …
