STUDY OF INCORPORATED DIVERSITY IN PHENOTYPIC FEATURESOF JNPT LINES OF RICE

Pratibha Choudhary, Naveen Patle2 and D. K. MishraDepartment of Plant Breeding and Genetics, J.N.K.V.V. Jabalpur (M.P.)

ABSTRACTOn the basis of DUS descriptor, 180 JNPT lines derived from Indica x Japonica sub-

species crosses of rice (Oryza sativa L.) with five checks were characterized for differentagro-morphological traits. A significant amount of variation was displayed for most of thetraits examined. The result revealed that maximum variation was recorded in lemmaand palea colour followed by panicle attitude of branches, leaf pubescence of blade surface,flag leaf attitude of blade (late), flag leaf attitude of blade (early), panicle distribution ofawns, spikelet density of pubescence of lemma, panicle exsertion, panicle curvature ofmain axis, panicle secondary branching, culm attitude, panicle awns and leaf intensityof green colour. The variation found in varieties will be utilized for the selection of

specific lines/varieties for protection, conservation and utilization for further breedingprogramme. This study will strengthen rice breeding programmes for the development ofnew varieties with specific traits resulting sustain for long time in seed chain. This alsoprovides help to isolation of the specific variety in the mixture of other lines.
