Abstract
Present study was undertaken to evaluate different morphological traits of rice advance lines. The experiment was laid out in randomized complete block design (RCBD) with ten rice advance lines replicated three times at National Tea and High Value Crops Research Institute (NTHRI) Shinkiari, Mansehra, Pakistan. Three plants per plot were selected randomly to record the important agro-morphological data viz. plant height, panicle length, number of tillers per plant, branches per panicle, flag leaf length, flag leaf width, flag leaf area, grain length, grain width and length/breadth (L/B) ratio were measured. All the recorded data was analyzed through SPSS 16.0 and Statistix 8.1. The results revealed that the vegetative growth attributes i.e. plant height was significantly increased in FH10-2 (152.7 cm), No. of tillers in FH4-1 (4.3), No. of branches in JP-6 (24.33), panicle length in Line 2(24) (49.6 cm), flag leaf length in FH10-2 (50.7 cm), flag leaf width in Super NPT-3 (4.3 cm) and flag leaf area in FH4-1 (143.6 cm), respectively. Furthermore, yield contributing attributes like grain length (8.5 mm) and Length/Breadth ratio (4.7) were significantly increased in FH4-1 and grain breadth in Super NPT-3 (2.8 mm). Among ten advance lines of rice, nine were recorded with slender grain shape while four advance lines were recorded with extra long slender and long slender grain size each.
