Abstract
Characterization of exotic germplasm of rice for qualitative traits was done in the Department of Plant Breeding and Genetics, College of Agriculture, Kerala Agricultural University during 2019. Eighty-nine exotic rice accessions received from IRRI, Philippines were characterized along with five check varieties. The experiment was set in augmented block design with five blocks. Accessions were characterized for qualitative traits as per DUS descriptor. Out of the 25 qualitative traits observed, eight each had one and two character states. The traits flag leaf attitude, lemma and palea colour, colour of apiculus, distribution of awns, panicle attitude of main axis, panicle exsertion, and pericarp colour were having three character states. Colour of awns and caryopsis shape had four classes. Qualitative traits, less affected by environment can be used as morphological marker for identifying genotypes. Twenty-two accessions with superior characteristics like erect leaf, erect flag leaf, erect and strong culm and well exserted panicle were identified.
