| dc.description.abstract | Abstract :
vperiment was conducted at the Laboratory of Agronomy Department, andhu Sheikh Mujibur Rahman Agricultural University, Gazipur from ■ : -.me, 2009-2010 to evaluate the rice (Oryza saliva L.) genetic resources for •■ierance to salinity. In this experiment for screening of rice genotypes one ,:•• •'v.d cultivars/landraces of rice including two check variety (Pokkali as TviiifdiU and 1R29 as susceptible) were used at germination stage up to 9^ day at U/, 15, and 20 dSnr1 (5:1 molar concentration of NaCl and CaCl2 solution).
Based on visual salt injury symptoms score (scale 1 to 9, where lower score denotes the tolerance and higher score denotes sensitivity) and 13 genotypes were found tolerant at 15 dSm-* salinity level. Among 13 genotypes, only Patnai23 showed higher germination index and seedling relative dry weight than check salt tolerant Pokkali at 15 dSnr1. Beside these, performance of Awned-1 and Soloi also well at this level. | en_US |
