    Effect of sowing dates on some yield components and yield of dry bean (Phaseolus vulgaris L.) cultivars
    (2004) Ceyhan, Ercan.
    The aim of this study was to evaluate the effect of sowing date on seed yield and yield components of dry beans. For this purpose, six dry bean cultivars (Sehirali-90, Karacaşehir, Akman-98, Göynük-98, Önceler-98 and Yunus-90) sown different dates were grown under Central Anatolia conditions in the 2000 and 2001. Analyses of variance indicated significant differences among sowing dates and cultivars with respect to seed yield. Based on mean values of years and cultivars, the highest seed yield (2800.36 kg ha{-1}) was obtained from May 4 sowing date. Based on mean of years and sowing dates the maximum seed yield (3038.08 kg ha{-1}) was achieved from Sehirali-90. Generally, seed yield decreases in delay sowing date. Correlations amongst the traits as well as their direct and indirect effects on seed yield were also calculated using correlations and path coefficients analysis, respectively. Relation between seed yield and number of seed per pod was positive and significant (r2 0.384**), with a direct effect of 88.15 % and indirect effects of 11.85 %, through thousand seed weight.

    Genetic and biochemical properties of Cicer spp reveal distinction between wild and cultivated chickpea genotypes
    (AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2019) Kafadar, Feyza Nur.; Özkan, Ali.; Can, Canan.; Kar, Yağmur.; Mart, Dürdane.; Ceyhan, Ercan.
    Chickpea (Cicer arietinum L.) is the third most important legumes after beans and peas in the world. Turkey is one of the main chickpea producing countries but the yield is not within the expected quantity considering cultivated area. Breeding chickpea varieties requires well-characterized wild Cicer spp progenitors including C. reticulatum, C. echinospermum, C. bijugum and C. pinnatifidum that exhibit sympatric distribution in the Southeastern Anatolia region of Turkey. This study contributes to the identification of similarities and differences among wild and cultivated Cicer spp. ecotypes using DNA marker systems and biochemical parameters. RAPD and ISSR markers revealed four groups and separated C pinnatifidum ecotypes as a single population. Wild Cicer spp and cultivated chickpea species exhibited significant variations for their oil, protein, starch, cellulose, fructose and sucrose content. Furthermore, the cultivated chickpea genotypes had higher content of fat, starch and sucrose than those of the wild progenitors whereas wild Cicer spp ecotypes possessed higher values for cellulose, fructose and glucose than cultivated chickpea genotypes.
