Uji Ketahanan beberapa Varietas Unggul Jagung terhadap Penyakit Gibberella dan Diplodia
Abstrak: Gibberella and
Diplodia ear rot is a disease that can damage the corn cobs and corn kernels
resulting in lower quality and quantity of seed. The objective of the research
are to find the varieties of corn which are resistant the ear
rot disease Gibberella and Diplodia. This study was conducted in Limang
Karo regency, North Sumatera, a randomized block design with three
replications, each treatment comprised 4 rows and each row contained 25 plants
with a spacing of 75 x 20 cm. The results showed 25 Hybrid maize tested against
Gibberella ear rot there are 7 Hybrid corn hybrids that are resistant to ear
rot Kenia-2, NK33, Bima 3, Bima 10 Bima
12 Q, NEI-9008 and X8B649 (check resistance) and moderately resistance there
are 9 hybrid that Kenia-3, DK979, NK22, P12, Gumarang, Srikandi putih, Lamuru
and Sukmaraga and 9 hybrid to ear rot
disease were reacted susceptible and highly susceptible. Whereas from 25 Hybrid
maize tested against Diplodia ear rot there are 6 Hybrid corn hybrids resistant
to ear rot disease is Kenia - 2, NK33, Bima 3, Bima 12 Q, NEI-9008 and X8B649
(check resistance) while that is moderately resistancet there are 11 hybrid
that is Kenia-3, DK979, NK22, P29, Bisi 2, P12, Bima 10, Gumarang, Srikandi
putih, Lamuru and Sukmaraga, while 8 hybrid others were reacted susceptible and
highly susceptible.
