    Effect of replications on estimation of the tuber yield and plant height in potatoes
    (1996) Budak N.; Yildirim M.B.
    Tuber yield is an important selection criterion in breeding programs conducted in diverse environments. It is important to precisely measure tuber yield within a location in order to make recommendations to farmers. The number of replications that should be measured to accurately determine tuber yield and plant height, and to detect the desired difference between potato genotypes, were determined using statistical formulas and data from a total of six yield trials in three diverse environments. Despite the environment diversity, measuring tuber yield and plant height on only two replications provided a very accurate estimate of the mean for each trial and of the detectable difference between two potato genotypes.

    Heterosis in bread wheat
    (1996) Budak N.; Yildirim M.B.
    Values of heterosis and combining ability for seven traits were estimated in a 6 × 6 diallel population by using Method 4 of Griffing type analysis. High heterosis was found for the harvest index and yield in the cross Orsa × Ak 702. which had the best specific combining ability. In crosses involving Orso and Ak 702, Orso reduced the plant height while Ak 702 increased it. For Harvest index, plot yield, and thousand kernel weight, Genaro and Marmara 86 were the best general combiners, while Gerek 79 and Ak 702 had the best general combining ability for plant height and number of tillers, respectively.

    Investigation of genotype X planting time interaction by using ammi statistical model in potatoes [Patateste genotip X dikim zamani i·nteraksiyonunun ammi i·statistik modeline göre i·rdelenmesi]
    (TUBITAK, 1999) Yildirim M.B.; Budak N.; Çalişkan C.; Çaylak Ö.
    In studies on potato planting time, the main effects of genotype and planting time were determined by variance analysis and are discussed. However, the main specific causes of interaction were not demonstrated clearly. Five potato genotypes (Resy. 81028/1, Sultan, Granola and Yaylakizi) were planted on six different dates (January 30, February 10. February 20. February 28, March 10 and March 20) in three different years (1993, 1994 and 1995). Tuber yield data were analysed with the AMMI (Additive Main Effects and Multiplicative Interaction) statistical model. The results showed that the January 30, February 10 and March 20 planting times had similar yield ranges. Granola and Resy gave low. Sultan and 81028/1 gave high and Yaylakizi gave moderate yields. The results clearly identify the main effects of the specific genotype and planting time, causing the genotype x planting interaction.
