Incorporation of AMMI Stability Value and Grain Yield in a Single Non-Parametric Index (GSI) in Bread Wheat

Abstract: In order to determine stable bread wheat genotypes with high grain yield via a single parameter, field experiments were conducted with 20 genotypes for 4 consecutive years in two different conditions (irrigated and rainfed) in a completely randomized block design with three replications in each environment. Combined analysis of variance showed highly significant differences for the GE interaction indicating the possibility of selection for stable entries. The results of additive main effect and multiplicative … Show more

“…For convenience, this disproportionate genotype response is referred to as crossover GEI. On the other hand, same sign or near zero scores represent a non-crossover (quantitative) GEI or a proportionate genotype response (Mohammadi et al, 2007;Mohammadi and Amri, 2008;Farshadfar, 2008).…”

“…By using these measures, suitable rice varieties can be identified for varying existing environmental conditions. Stability per se should however not be the only selection parameter because the most stable genotypes would not necessarily give the best yield performance (Mohammadi et al, 2007;Mohammadi and Amri, 2008); hence, there is a need for approaches that incorporate both mean yield and stability in a single index and that is why various authors have introduced different selection criteria for simultaneous selection of yield and stability (Eskridge, 1990;Kang, 1993;Dashiell et al, 1994;Bajpai and Prabhakaran, 2000;Rao and Prabhakaran, 2005;Farshadfar, 2008;Babarmanzoor et al, 2009). In this regard, since ASV takes into account both IPCA1 and IPCA2, most of the variation in the GE interaction is justified; therefore, the rank of ASV and yield mean is such that the lowest ASV is rank one, while the highest yield mean is rank one and the ranks are then summed in a single simultaneous selection index of yield and yield stability called the yield stability index (YSI).…”

“…Various authors have proved that stability indices are genetic and hence heritable (Patanothai and Atkins 1974;Busch et al, 1976;Dhillon and Singh, 1977;Lin 257 and Binns, 1988;Farshadfar et al, 1999). If stability is heritable, the next step in the genetic analysis is the identification of the chromosomal location of the genes controlling adaptation (Eskridge et al, 2000;Farshadfar, 2008). Various techniques (biometrical, cytogenetic and molecular) have been used to locate the genes monitoring quantitative traits, among which cytogenetic methods (monosomic, disomic, substitution and disomic addition analysis) have been widely used (Morgan, 1991;Kőszegi et al, 1996;Farshadfar and Sutka, 2003).…”
