One hundred and eighty seven traditional varieties/landraces of rice (Oryza sativa L.,) were characterized following the 62 DUS descriptors. The data was recorded on 44 qualitative and 18 quantitative characters. The rice landraces under study recorded a wide range of variability for most of the morphological traits studied. Out of 62 characters studied, five characteristics were found monomorphic viz., leaf ligule, shape of ligule, leaf collar, male sterility and Endosperm: Presence of amylose, remaining characters registered variations among the landraces. Spikelet: Colour of tip of lemma, Panicle: Colour of awns (late observation) and decorticated grain: Shape recorded six states of expression. The descriptors registered maximum variation were decorticated grain: Colour [7] and Lemma and Palea: Colour [9] . Wide variation among the DUS characters indicated wide genetic variation among the landraces under the study, which may be utilized for crop improvement programmes. Not Available |
