An investigation was undertaken to study the feasibility of sugarbeet cultivation under Bangladesh condition during winter season of 2009-2010. Seeds of 14 sugarbeet genotypes were sown in the experimental field of Horticulture Research Centre of BARI, Gazipur on 10 November 2009. Visible root swelling in all genotypes started between 36 and 40 days after sowing (DAS). Nine genotypes had white ...
Mahalanobis’ D-square (D2) statistics was applied to assess diversity in the 9 genotypes collectedof semi-arid region of India (7 genotypes from Gujarat and Rajasthan for normal toxic and two fromOrissa csmcri’s plantation of non toxic nature. These genotypes were grouped into five. Cluster I andIII had two genotypes, cluster II had three genotypes and cluster VI and V contributed as solitaryge...
Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). Many studies have identified Zn-efficient rice genotypes, but causal mechanisms for Zn deficiency tolerance remain poorly understood. Here, we report a detailed study of the impact of Zn deficiency on crown root development of rice genotypes, differing in their tolerance to this stress. Zn deficiency delayed c...
Seedlings of selected six genotypes of maize (Zea mays L.) differing in their drought sensitivity (LM5 and Parkash drought-tolerant and PMH2, JH3459, Paras and LM14 as drought-sensitive) were exposed to 72 h drought stress at two leaf stage. Alterations in their antioxidant pools combined with activities of enzymes involved in defense against oxidative stress were investigated in leaves. Activi...
Using Mahalanobis D2statistics, the level of genetic diversity among soybean genotypes based on 12 agro-morphological traits was investigated in this study. A total 100 were grouped into six clusters. Cluster I had maximum number (53 genotypes), followed by cluster II (37 III (6 clusters IV and V (1 genotype each), VI (2 genotypes). Clusters greatest inter-cluster distance (117618.10). Intra-cl...
Soil moisture is one of the most important determinants of plant’s seed germination, emergence and finally yield formation in arid and semi-arid zone (e.g. IRAN). In such a situation, the selection of a cultivar resistant to drought is the most important task. In this regard, a research at three levels (Farm, Greenhouse, Laboratorial) was conducted to study 10 genotypes with three improved back...
Identification of genotypes adapted to a particular region is of special interest to breeders and plant geneticists. In order to identify adapted genotypes in sesame lines based on multi-trait selection, an experiment was conducted in a completely randomized block design with four replications at Moghan Agricultural Research Station of Ardabil Agricultural and Natural Resources Research and Edu...
In order to evaluate drought tolerance of some safflower genotypes, an experiment was conducted at the Research Farm of Isfahan University of Technology in 2016 and 2017. In this study, 18 safflower genotypes selected from different local populations along with 2 exotic cultivars and one local population (21 genotypes) were separately evaluated at two normal (non-stress) and water deficit (s...
Norovirus (NoV) is an etiological agent of acute gastroenteritis in humans. Genomic recombinations NoV occur mainly at the junction genes encoding RNA-dependent RNA polymerase (RdRp) and major capsid protein (viral 1, VP1), which may produce strains with novel combinations VP1- RdRp-genotypes. Here effect on changes proportions VP1-genotypes was examined through analysis observed frequencies Ja...
Extended Abstract Introduction and Objective: The sunflower is one of the most important oilseed plants in the world and its oil has nutritional and high economic value. Identification and selection of high-yielding genotypes with desirable characteristics are especially important in this plant. Evaluating sunflower genotypes under different environmental conditions would be useful to identify...
