    In this study, the water saving and conservation potential of various furrow irrigation management techniques for irrigated cotton were compared. Conventional every-furrow irrigation with open-end furrows (EFO) and blocked-end furrows (EFB), and alternate every-other-furrow management with open-end furrows (AFO) and blocked-end furrows (AFB), were considered. Considerable seasonal water savings were obtained with AFO and AFB flows, on average from 717 mm to 906 mm, respectively, when compared to EFO. Alternate furrows showed the ability to reduce tailwater runoff considerably. When compared with EFO, water use was reduced by 9063 m(3) ha(-1) (60%) using AFB and 7167 m(3) ha(-1) (48%) using AFO, with decreases in yield of 765 kg ha(-1) (27%) and 492 kg ha(-1) (17%), respectively. Similarly, average water use efficiencies were 0.36 kg m(-3) for AFB and 0.31 kg m(-3) for AFO, compared to 0.20 kg m(-3) for EFO. Results showed the possibility of applying alternate-flow furrow management techniques for water conservation in cotton irrigation. Additionally, the alternate furrow method could also be considered as a deficit irrigation approach in the Harran Plain.

    MOLECULAR CHARACTERIZATION OF SOME SELECTED PERSIMMON GENOTYPES AND CULTIVARS BY SRAP AND SSR MARKERS

    In this study, SRAP and SSR markers were employed to determine genetic relationships among 42 persimmon genotypes (Diospyros kaki Thunb) obtained from Hatay province and 3 persimmon cultivars, 2 of which belong to Diospyros kaki Thunb and one belongs to Diospyros oleifera Cheng. Genetic relationships were determined by using a total of 29 molecular DNA primers (SRAP and SSR). Of these primers, 21 SRAP primer combinations produced a total of 107 bands and 77.6% of them were polymorphic; 8 SSR primers produced 26 polymorphic bands with an average polymorphism ratio of 84.6%. The SRAP and SSR markers produced 4.6 bands as average and the number of bands produced per marker was calculated as 3.6. The lowest similarity was observed between MK-113 (Diospyros oleifera Cheng) and the other genotypes all belongs to Diospyros kaki Thunb (with similarity ratios of 0.41-0.69 for SRAP primers, between 0.25-0.67 for SSR primers). The genotypes/cultivars belongs to Diospyros kaki had similarity ratio between 0.98-1.00 according to SRAP and SSR markers. This synonym or similarity could be results of clonal propagation rather than autogamy.
