Characterization of Some AUS Rice Genotypes for Yield Traits

The investigation was carried out under field conditions to characterize yield contributing traits of eighteen (18) advanced Aus rice lines (F5) and three commercial check varieties. The experiment was conducted in a randomized complete block design (RCBD). The field was divided into three blocks; each block was sub-divided into 21 plots (lines) where genotypes were randomly assigned. The experiment was conducted during the period of Transplanting Aus season (April 2015 to August 2015) at the genetics and plant breeding experimental field of Sher-e-Bangla Agricultural University, Bangladesh. All the genotypes were characterized and categorized as per the descriptors developed by Biodiversity International, IRRI and WARDA-2007 for DUS test of inbred rice. All the genotypes were grouped and classified as well as described based on yield contributing characters as per descriptors so that all the observed genotypes containing described characters can be easily evaluated and identified at a glance for further studies.
