Production of pure lines is an important step in biological studies and breeding of many crop plants. The major types of pure lines for biological studies and breeding include doubled haploid (DH) lines, recombinant inbred lines (RILs), and near isogenic lines (NILs). DH lines can be produced through microspore and megaspore culture followed by chromosome doubling while RILs and NILs can be pro...
This study was conducted to investigate the phenotypic diversity of 108 pure barley lines in Augment design with four controls in six blocks in the farm of Darab Agricultural Research Station (2020-2021). In order to select the best lines in terms of yield and other traits, SIIG index was used. The results of restricted maximum likelihood (REML) analysis showed that the lowest and highest level...
Plastic deformation in the form of slip lines is observed in front of notches in pure epoxy and robber-toughened epoxy specimens under four-point bending. In contrast to the case for pressure-insensitive materials, the angles between two families of slip lines emanating from notch surfaces are not 90°: they are smaller than 90 ° under tension, but they are larger than 90 ° under compression. Fo...
