Kahramanmaraş koşullarında, yerel ekmeklik buğday genotiplerinde fizyolojik karakterler yönünden mevcut varyasyonun belirlenmesi amacıyla yapılan bu çalışmada, 14 yerel ekmeklik buğday genotipi ve 3 standart çeşit materyal olarak kullanılmıştır. İncelenen özelliklerin çoğunda genotipler arasındaki farklar önemli bulunmuş, yaprak alanı (ZD:31 ve ZD:65), yaprak alan indeksi (ZD:31 ve ZD:65), özgül yaprak alanı (ZD:14-15, ZD:31 ve ZD:65) ve olgunlaşmadaki biyomas yönünden üstün özelliklere sahip yerel genotiplerin bulunduğu belirlenmiştir.
Anasap yaprak alanında sapa kalkma başlangıcından çiçeklenme dönemine kadar olan sürede artış söz konusu olurken, yaprak alan indeksinde sapa kalkma başlangıcı ile çiçeklenme dönemi arasındaki sürede azalış söz konusu olmuştur. Dört yapraklı dönemde özgül yaprak alanı her iki yılda da birbirine yakın değerler göstermiş, sapa kalkma döneminde özgül yaprak alanı değeri ilk yıl düşerken ikinci yıl artmış, çiçeklenme döneminde ise her iki yılda da azalma meydana gelmiştir. Bu değişimlerde özellikler arası ilişkilerin her dönemde farklı ortaya çıkmasına sebep olmuştur. Tane verimi ile; sapa kalkma başlangıcı (ZD:31) ve çiçeklenme dönemindeki (ZD:65) ana sap yaprak alanı, dört yapraklı dönemdeki özgül yaprak alanı (ZD:14-15), sapa kalkma başlangıcındaki özgül yaprak alanı (ZD:31), tane dolum periyodu, yaprak alan süresi ve olgunlaşma dönemindeki biyomas arasındaki ilişkilerin olumlu ve önemli, sapa kalkma başlangıcındaki yaprak alan indeksi (ZD:31), çiçeklenme dönemindeki özgül yaprak alanı (ZD:65) arasındaki ilişkilerin olumsuz ve önemli olduğu belirlenmiştir.
