Additive Main Effects And Multiplicative Interactions Analysis Of Yield Performances In Bread Wheat Genotypes Across Environments, Yüksel Kaya, Çeti̇n Palta, Seyfi̇ Taner

This study was carried out to determine the yield performances of 20 bread wheat genotypes across six environments in Central Anatolia, Turkey, in the 2000-2001 growing season. The experimental layout was a randomized complete block design with four replications. Additive main effects and multiplicative interactions analysis (AMMI) indicated that the yield performances of genotypes were under the major environmental effects of genotype by environmental interactions. The first two principal component axes (PCA 1 and 2) were significant (p < 0.01) and cumulatively contributed to 78.64% of the total genotype by environment interaction. A biplot generated using genotypic and environmental scores of the first two AMMI components also showed that genotypes with larger PCA 1 and lower PCA 2 scores gave high yields (stable genotypes), and genotypes with lower PCA 1 and larger PCA 2 scores had low yields (unstable genotypes), as in the sites tested.
Effects Of Girdling, Ga3 Applications And Additional Nutrient Applications On Fruit Yield, Fruit Set And Fruit Size In The Clementine Mandarin, Turgut Yeşi̇loğlu, Ebru Cücü Açikalin

In small fruit species, like the mandarin, fruit size is lower in Turkey than in other countries and this has a negative effect on their marketing. There are problems with fruit yield and size in the Clementine mandarin, which is a commonly grown mandarin cultivar in Turkey. To solve these problems, various studies have been carried out. Girdling is one of the methods studied and it had positive effects on fruit yield and size without lowering the fruit quality. However, fruit yield and fruit size were reduced to previous levels if the treatment was repeated over a long period. In …

This experiment was carried out to determine the yield and oil contents of jojoba populations that were derived from a base population raised from seed in Antalya between 1999 and 2001. In the first year 59 types were evaluated, and 19 promising types were determined. In the second and third years experiments were conducted on these 19 types. Chilling, insect and disease damage was not seen during the experiment periods. However, some plants were dead where water ponded after heavy rains. The mature seeds were hand collected after they fell onto the soil in September, and their yield and oil …
