Morphological diversity on fruit characteristics among some selected mulberry genotypes from Turkey.

Abstract

Turkey hasimportant mulberry genetic resources .In contrastto the other mulberry producing countries, in Turkey mulberry treeis usedonly for fruit production not for sericulturSome selectedmorphological fruit characteristics such asseedformation, fruitweight,SSC (Soluble solid content), titratableacidity, juice yield and pH of 34 selected mulberry genotypes found togetherin anex-situcollection parcel in Mala tya Fruit Research Institute in Turkeywere investigated. The collection parcel has been established in 1996 year with 3x5 m row spacing. The morphological fruit characteristics are represented of 3 years average data (2006 -2008). The results showed that t here were big differences among genotypes in terms of most of the fruit characteristics. Fruit weight varied from 0.66 (Istanbul dutu2) to 3.07 (Gumushaci beyaz); SSC varied from 17.33% (Erzincan karadut16) to 30.67% (Lokum dut ); titratable acidity varie d from 0.06% (Angut 9) to 1.62% (Gumushaci kara dut 8)andpH varied from 2.19 (Kemaliye karadut9) to 5.86 (Mersin mor dut) , respectively .
