ABSTRACT

Twenty cultivars of rice were studied to know various morphological characters responsible for
identification of rice cultivars. The study revealed that plant morphological characters viz, awn
length, panicle length, leaf blade colour and leaf sheath colour were found as the most important
morphological characters for varietal identification in rice.Other morphological characters viz. node
base colour, awning, distribution of awns, anthocyanin colouration of stem nodes and internodes
and stigma colour were of secondary importance for identification of rice cultivars. On the other
hand, leaf pigmentation, flag leaf angle, colour of lemma and palea, leaf hairiness, secondary
branching of panicles, secondary branching pattern of panicles and attitude of panicle branching
were not helpful in distinguishing the rice cultivars.
