IDENTIFIKASI KULTIVAR LOKAL PADI SAWAH (Oryza Sativa L) KALIMANTAN TIMUR BERDASARKAN KARAKTER AGRONOMI DAN MORFOLOGI
Abstrak: The objective of this
researchis identification local low land rice cultivars explored based on
morphological and agronomical character from East Kalimantan. This research
used single plot and single plant method. The data were then analyzed by computerized
Cluster Analysis. Research result showed identification stalk and plant
heightwas found that most cultivar were medium height (> 130 cm), medium
stalk diameter (5-7 mm), large amount of tillerand productive tiller (> 25
tillers). Identification on morphological character or traits of ligule and
leaf showed that all cultivars had colorless or white and split-shaped ligules,
light green collars, and light green auricles. Most of them had ligules of
medium length (> 20 mm), leaves of medium length ( 61-80 cm), narrow leaf
width (1-2 cm), smooth leaf surface, and green colored leaves.The results of
identification on morphological traits of panicle and grain showed that any
cultivar have axis of panicle floppy and that a greater part of the cultivars had
long panicles (>25 cm), compact and straggle or dense panicles, relatively
large amount of secondary branches, panicle position is a little above the flag
leaf, rice grain most of which were tilled with yellow strawcolor, stigma of
rice with yellow strawcolor, head pistil with white color, palea lemma with
yellow strawcolor, lemma sterile turn yellow straw color with sterile length of
lemma in short criterion.The result of cluster analysis combination of all
existing traits or character indicated that 26 local low land rice cultivar of
East Kalimantan identified there were not found cultivarsof 100 % similar.
