Defining subregions and estimating benefits for a specific-adaptation strategy by breeding programs: a case study.

From: Crop Science | Date: September 1, 2005| Author: Annicchiarico, Paolo; Bellah, Fadila; Chiari, Tiberio | Copyright information

Producing specific varieties for each subregion of a target region, instead of widely adapted varieties, may exploit positive genotype x location (GL) interactions to increase crop yields. With reference to the Algerian durum wheat (Triticum durum Desf.) region, as defined in a Geographic Information System (GIS), this study aimed at (i) comparing additive main effects and multiplicative interaction (AMMI) vs. joint regression modeling of GL effects, (ii) verifying the reliability of a GIS-...

Benefits of Cooperation Between Breeding Programs in the Presence of Genotype by Environment Interaction
Journal of Dairy Science ; ABSTRACT Dairy cattle breeding programs and dairy farmers are selecting sires and dams across environments. Genotype environment interaction (G E) limits the possibilities for cooperation between breeding programs operating in different environments. The objectives of this study were 2-fold: 1) to
Genetic Progress from 40 Years of Orchardgrass Breeding in North America Measured under Hay Management.(Statistical Data Included)
Crop Science ; ORCHARDGRASS (cocksfoot) is a widely grown perennial forage grass used for both hay, silage, and pasture in North America. It is grown in 45 of the 48 contiguous United States (van Santen and Sleper, 1996) and in all Canadian provinces (Lawrence et al., 1995) where it is adapted to a wide range of
Cultivar adaptation across Italian locations in four turfgrass species.
Crop Science ; TURFGRASS SEED TRADE is a consolidated sector of modern agriculture because of the importance of turfgrass germplasm to establish recreational and sport field areas on the one hand and grassy ground covers for orchards, vineyards, roadsides, and ski runs on the other (Beard and Green, 1994).

Trends over time among cotton cultivars released by the Oklahoma agricultural experiment station.
Crop Science ; NUMEROUS STUDIES in cotton have described long-term trends in lint yield, fiber properties, and agronomic characters for the cultivars developed over time in selected regions of the Cotton Belt, in individual states, or in particular breeding programs. Most of these investigations have compared
Biplot analysis of forage combining ability in maize landraces.
Crop Science ; ENSILING MAIZE stabilizes forage availability throughout the year, since it permits a supply of good quality forage when seasonal production is low. Although the whole maize plant (ears plus stover) is used for silage, most hybrids utilized for silage were selected for grain production alone.
