Karpuz Melezlerinde Tohum Kabuk Rengi Kalıtımının Belirlenmesi

Bu çalışmada, Alata Bahçe Kültürleri Araştırma Enstitüsü Müdürlüğü karpuz gen havuzunda bulunan 11 adet hat ve bu hatlardan resiprokal olarak elde edilen melezlerin tohum renginin ve tohum iriliğinin kalıtım modeli ortaya konmuştur. Tohumlarda UPOV’a göre; büyüklük (çok küçük, küçük, orta, büyük, çok büyük), kabukta zemin rengi (beyaz, krem, yeşil, kırmızı, kızıl kahve, kahverengi, siyah), kabuğun ikincil rengi (yok, var), kabuğun ikincil renginin dağılım şekli (nokta, parça, nokta ve parça), zemin rengi ile ikincil rengin alan ilişkisi (küçük, orta, büyük), hilumda leke (yok, var), kenarda leke (yok, var) karakterleri gözlemlenmiştir. Yapılan gözlemlerde; 2 hat ve 5 melezde siyah renk, 3 hat ve 8 melezde kahverengi renk, 1 hatta kızıl kahve renk ve 1 hatta beyaz renk oluştuğu, 5 hat ve 9 melezde büyük tohum, 1 hat ve 4 melezde küçük tohum ve 1 hatta çok küçük tohum oluştuğu, 2 hat ve 4 melezde hilumda leke oluştuğu ve tüm hat ve melezlerde tohum kenarında leke oluşmadığı gözlemlenmiştir.

Determination of the Seed Coat Color Inheritance in Some Watermelon Hybrids

In this study, 11 lines in the watermelon gene pool of Alata Horticulture Research Institute Directorate and the inheritance model of the seed color and seed size of the hybrids obtained from these lines were revealed. According to UPOV; size (very small, small, medium, large, very large), ground color of testa (white, cream, green, red, red-brown, brown, black), secondary color of testa (absent, present), type of distribution of secondary color of testa (in dots only, in dots and in patches, in patches only), area of secondary color in relation to that of ground color (small, medium, large), patches at hilum (absent, present), patches at margin (absent, present), were examined for these parameters. Observations made; black color in 2 lines and 5 hybrids, brown color in 3 lines and 8 hybrids, one red-brown color and 1 line white color, big seeds in 5 lines and 9 hybrids, small seeds in 1 line and 4 hybrids and 1 line very small seeds, patches at hilum in 2 lines and 4 hybrids and no patches at margin of the seed.
