Mineral Composition of Inbred Confectionary Pumpkin Candidates from Turkey Originated Populations

Abstract

Turkey is one of the most important countries in the production of confectionary pumpkin. The aim

of the study is to reveal the amount of some mineral elements in seed coat and the seed of confectionary pumpkin

candidates which gathered from different regions of the country and reached in S5 level. In the present study, a

total of twenty-seven pumpkin genotypes which were self-pollinated to the level of S5 and two local population

characterized genotypes were used as plant material. Contents of P, K, Ca, Fe, Mg, Mn, Cu, S and Zn minerals were

determined in the seed coat and seed, separately. Results of the study indicated that the highest content inside of

the seeds as following genotypes; “A14” and “A25” for P, “A14” for K, “B17” and “A8” for Ca, “B33” and “C24”

for Fe, “A14” for Mg, “C30” and “A32” for Mn, “A14” for Cu, “A14” for S and “A14” for Zn. Seed coat produced

the highest content as following; “B14” for P, “A14” for K, “A11” for Ca, “C25” and “B25” for Fe, “A11” for

Mg, Ürgüp Sivrisi (population characterized) for Mn, “A33” for Cu, “C18” for S and “A14” for Zn. Consequently,

“A14” was found as the highest content of nutritional compounds.

Türkiye’den Toplanan Popülasyonlardan Elde Edilen Çerezlik Kabak Çeşit Adaylarının Mineral Madde İçerikleri

Abstract

Türkiye, çerezlik kabak üretiminde en önemli ülkeler arasındadır. Çalışmanın amacı, ülkenin farklı

bölgelerinden toplanan ve S5 kademesine ulaştırılan çerezlik kabak ıslah hatlarında tohum kabuğu ve tohumdaki

bazı mineral maddelerin miktarını ortaya koymaktır. Bu çalışmada, S5 kademesinde yirmi yedi kabak genotipi ve

genotip olarak karakterize edilmiş iki yerel popülasyon kullanılmıştır. Tohum kabuğu ve tohumda P, K, Ca, Fe,

Mg, Mn, Cu, S ve Zn minerallerinin içeriği ayrı ayrı belirlenmiştir. Araştırma sonuçlarında, tohum içerisindeki

en yüksek mineral madde içeriği P için “A14” ve “A25”, K için “A14”, Ca için “B17” ve “A8”, Fe için “B33”

ve “C24”, Mg için “A14”, Mn için “C30” ve “A32”, Cu için “A14”, S için “A14” ve Zn için “A14” hatlarında

belirlenmiştir. Tohum kabuğunda ise P için “B14”, K için “A14”, Ca için “A11”, Fe için “B25” ve “C25”, Mg için

“A11”, Mn için Ürgüp Sivrisi (popülasyon), Cu için “A33”, S için “C18” ve Zn için “A14” hatlarında en yüksek

değerler gözlenmiştir. Sonuç olarak A14 en yüksek mineral madde içeriğine sahip genotip olarak tespit edilmiştir.
