Abstract:

In present study fifteen advance lines of rice (Line-95, Line-168, Line-133, Line-50, Line-79-L, Line-146, Line-149, Line-2, Line-29, Line-35, Line-54, Line-127, Line-64, Line-86-2, Line-71) were evaluated in the background of JP-5 (control) for Quantitative and Qualitative traits. Mean value for quantitative traits were compared according to least significant difference (LSD) statistical test. Data on morphological parameters (qualitative and quantitative) was collected from productive tillers of every three plants of each variety at suitable phase of growth to check variation. Findings were recorded according to IRRI description morphology and varietals characteristics. The material exhibited considerable inconsistency for qualitative and quantitative characters with few exceptions. Genetic distance based on SDS PAGE analysis ranges from 0–70%. Dendogram was constructed which divided sixteen genotypes in six groups (A – F) comprising of 3, 2, 5, 1, 3 and 2 genotypes, respectively. The advance rice lines such as Line-2, Line-29, Line-35, Line-54, Line-127 and Line-86-2 showed good physical characteristics (grain length, grain width, L/B ratio, chalkiness). While grain quality traits (GT, GC) were excellent in advance Line-95, Line-168, Line-2, Line-35, Line-54, Line-127, Line-64 and Line-71. However, highest yield/plant was recorded in Line-86-2 (162g), Line-79-L (134.9g), Line-71 (116.5g), Line-95 (114.1g), Line-168 (110.1g) and Line-149 (103.7g). Our findings showed great variations in morphological, physical and biochemical traits of advance rice lines and these variations may be exploited to develop high yielding and high quality rice either through breeding or by genetic engineering.
