Russian Wheat Aphid (RWA) is a serious pest of wheat, barely and other small grains in cereal-producing regions of the world. The use of resistant cultivars is an effective management strategy to control this pest. In this study, 15 lines and 13 cultivars of durum and bread wheats along with two resistant and susceptible controls were used to evaluate their reaction to RWA under greenhouse cond...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
Background: The YMD is one of the serious viral diseases in blackgram and being transmitted by whitefly (Bemisia tabaci). development YMV resistant varieties important aspects for sustainable production. Marker assisted selection genetic transformation could be utilized developing genotypes. Methods: We attempted to map QTLs governing resistance employing parents i.e., PBG32 (susceptible) PU31 ...
Thirteen betelvine cultivars (PB 001 to PB 013) collected from different locations of Bangladesh showed remarkable variations in disease reaction foot and root rot caused by Sclerotium rolfsii. The lowest incubation period 8 days was required for the 005 (BARI line), 006 (Misti pan), 009 Pan-1) 010 (Bangla pan) highest 22 (Laldingi 013 (Gayasur appearance 1st symptoms. incidence ranged 8.33 100...
Sesame is one of the plants that due to the high content (47-52%) and high quality (low cholesterol and some antioxidants) its seed oil, important role has in human health. An experimental with objective to evaluate eight local landraces of sesame to drought stress based on grain yield and drought tolerance indices using factorial split plot design was conducted with three replications in resea...
the soybean cyst nematode (heterodera glycine ichinohe, scn) is one of the most serious yields limiting pathogen on soybean (glycine max (l.) merr) which is found in many soybean–growing regions throughout the world. applying of resistant sources is one of the efficient measures to manage this nematode. in this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in f...
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
