dc.description.abstractTwenty cultivars of rice were studied at Rice Research Station, Kaul, Chaudhary Charan Singh Haryana Agricultural University, Hisar during 2006-2007. The study revealed that plant morphological characters viz. awning, panicle length, plant habit, Node base colour, stigma colour, Anthocyanin coloration as stem, node and internodes are the most important diagnostic characters to variety identification in rice. Stigma colour, attitude of branching of panicle, flag leaf angle are also helpful in testing the varietals purity of rice. There are only two characteristics (leaf Pigmentation and hairiness on leaf blade) which are not very much helpful in distinguishing the rice variety. The study also concludes that the seed morphological characteristics such as Kernel length, breadth, L/B ratio, hundred seed weight, grain yield, husking percentage, milling percentage and head rice recovery also proved to be very helpful in varietals identification. The differential response of paddy varieties to phenol, FeSo4, NaOH, modified phenol and KOH-bleach test was found to be accurate means of classification. The reaction which was observed on the husk was distinct and consist ant. It is, therefore, concluded that the field morphological characters and the laboratory parameters could be used for genetic purity testing.en_US
