Abstract
Thirty advanced T-aman rice (Oryza sativa L.) breeding lines along with four checkswere studiedat the experimental farm of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh. The experiment was conducted following Randomized Complete Block Design (RCBD) with three replications. The objective of the study was to know variabilityin yield,yield contributing characters and earliness of studied lines, and to identifyshort duration rice genotypes at F9 generation. The genotypes differed significantly for plant height (cm), length of panicle, total number of tiller per hill, effective tiller number per hill, filled grains per panicle, unfilled grains per panicle, days to 50% flowering, days to maturity, 1000 grains weight and yield per plot (Kg plot-1). Considering all the traits genotype R7 was the earliest compared to all other genotypes which took 113 days for maturity. The genotype R16 recorded the highest yield, took 118 days for maturity, and that was significantly higher than check varieties. Phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the traits studied indicating that the measured traits interacted with the environment to some extent. Allthe studied traits expressed moderate to high heritability estimates. High heritability along with high genetic advance was noticed for the following traits: number of filled grain per panicle, number of unfilled grain per panicle and plant height. Data suggests a few promising breeding lines might be potential as short duration and high yielding T-aman variety.
Keywords: Oryza sativa, variability, GCV, PCV, heritability, genetic advance, F9 generation and advanced breeding lines
