Evaluating chickpea lines for disease resistance in western Nebraska

Chickpeas (Cicer arietinum) are a newly emerging alternative crop for western Nebraska. Interest in this crop is increasing with approximately 4,000 hectares cropped per year over the last 5 seasons. Several disease problems have been identified that will limit optimal production success if left unchecked. These diseases include Ascochyta blight, caused by A. rabiei, and a root disease complex consisting of Rhizoctonia solani, Fusarium spp., and Pythium spp. Thus trials were conducted at multiple locations (2003–2004) throughout the Nebraska Panhandle for testing chickpea lines and cultivars for yield potential and tolerance to both types of diseases under both dryland and irrigated conditions. Differences were observed between entries and their yield response to the different irrigation systems. In general, those entries with better root disease tolerance tended to yield better from irrigated production, while those more susceptible to disease performed better under dryland conditions. Identification of better sources of resistance is encouraging for the new chickpea industry in Nebraska and this process will continue as interest and production expands

Yield and Agronomic Traits of Waxy Proso in the Central Great Plains

Proso (Panicum miliaceum L.) is a summer annual grass capable of producing seed in 60 to 90 d. This characteristic, and its efficient use of water, makes it well suited to the short, and often hot and dry, growing season in the high plains of the central Great Plains. The introduction of novel end-use characteristics such as waxy starch can stimulate an increased market for proso. We evaluated 18 experimental F5 waxy lines derived from a cross of ‘Huntsman’ and PI436626 across seven locations. Genotype × environment variation in waxy proso was mostly a matter of changes in magnitude and not crossover interaction. When crossover interaction was implicated, it was generally slight and occurred at lower environmental means—at locations with low mean response to any given variable. Waxy progeny mean yield was lower than Huntsman but significantly higher than PI436626. Except for test weight, waxy progeny mean response for most traits was similar to check cultivars. Mean yield of one experimental line did not differ significantly from Huntsman, and 14 did not differ significantly from ‘Horizon’, the second highest yielding cultivar. In addition, regression analysis suggests that top-yielding waxy lines responded well to high-yield environments. Seed sizes for all waxy lines were smaller than the check lines, but most were significantly larger than PI436626. Waxy lines generally headed at a similar time to Huntsman and the other non-waxy checks, and most were significantly earlier than PI436626. Late maturity of PI436626 was the main factor limiting its culture in the High Plains region

G80-487 Spring Small Grains Variety Selection (Revised January 1992)

Tests indicate which varieties of oats, barley and spring wheat are best adapted to Nebraska growing conditions. The primary spring small grain grown in Nebraska is oats. Oats are grown throughout the state, but production is concentrated in the east and northeast cropping districts. Nebraska\u27s estimated harvested oat acreage in 1989 was 310,000 acres. Spring barley production is centered in the northwest and southwest districts. Harvested barley acreage in 1990 was 30,000 acres. Barley is commonly grown as an early summer feed grain and corn substitute. Spring wheat production in Nebraska is concentrated in the northern section of the state where conditions limit reliability of winter wheat
