Description
Penelitian ini bertujuan untuk mendapatkan klon harapan gladiol yang tahan terhadap layu fusarium.Rancangan yang digunakan adalah acak kelompok pola faktorial. Faktor (1) klon-klon harapan gladiol, terdiri dari96212/168; 96210.2/20; 96215/49; 96203.2/14; 9607.2/129; 96215/202; 96215/122; 96204/69; 96213/109;96210.1/170; hol land merah; dan 621-1. Faktor (2) kerapatan inokulum F. oxysporum, terdiri dari 0 sel konidia/gtanah; 104 sel konidia/g tanah; 108 sel konidia/g tanah. Hasil percobaan menunjukkan bahwa gladiol dengan nomorklon 96215/49; 623-1 dan 96213/109 merupakan klon harapan gladiol yang pal ing tahan terhadap layu F. oxysporumf. sp. dan klon 9612/168 merupakan klon yang pal ing rentan. Re sponse of glad i o lus prom -is ing clones to Fusarium oxysporum f. sp. glad i oli. The aim of the ex per i ment was to ex am ine the re sis tance of glad i -o lus clones to fusarium wilt. Fac to rial randomized block de sign was used in the ex per i ment. The first fac tor wasglad i o lus prom is ing clones, con sist of 96212/168; 96210.2/20; 96215/49; 96203.2/14; 9607.2/129; 96215/202;96215/122; 96204/69; 96213/109; 96210.1/170; hol land merah; 621-1. The sec ond fac tor was den sity of inoculum F.oxysporum, con sist of nill conidia/g soil; 104 cells conidia/g soil; and 108 cells conidia/g soil. The re sults showed thatthe glad i o lus clone num ber 96215/49; 623-1 and 96213/109 were the most re sis tant to Fusarium oxysporum f. sp.glad i oli and clone num ber 9612/168 was the most susceptible.
