Estimation Genetic Stability of Faba bean (Vicia faba L.) Genotypes in Sallahaddin Governorate

Abstract

A field experiment was Carried out at two Locations (First: Field Crops station research \\ Collage of agriculture \\ university of Tikrit) and The Second in the agricultural Farm in AL-Houaish District of Salahaddin Province during 2017-2018 winter season to study the stability of some Faba bean genotypes (po6-oo1FB/FL, PO6-OO3FB/FL, PO6-OO5FB/FL, PO6-OO9FB/FL, PO6-O11FB/FL, PO6-O14FB/FL, Syrian Local 1arge and Aguadolce) introduced from ICARDA. Three distances among plants (20, 30 and 40 cm) was used. Factorial Randomized completely Block Design with–three replications was used. Result Showed that: most studied genotypes can be predicted by using linear function in most traits except protein percentage.(PO6-OO3FB/FL) and (PO6-OO5FB/FL) genotypes were stable ( coefficient of regression nearest to one ) in individual plant seed yield, and number pods.plant−1 and number seeds. pod−1, while (PO6-O11FB/FL) and (PO6-O14FB/FL) were stable in plant height, number pods. Plant−1, 100 seed weight and total seed yield. Therefore, PO6-OO5FB/FL followed by(PO6-O14FB/FL) produced high and stable seed yield also were stable in both in individual and efficiency plant yield and adapted for poor environments which can be regarded as a good stable genotype in Salahaddin Governorate environments.
