Drought stress is one of the most important factors limiting production in the agricultural sector. Due to the need to use smart agriculture adapted to climate change, the use of drought-tolerant alternative plants with high water use efficiency is of great importance. Foxtail millet (Setaria italica L.) is one of the important drought tolerant fodder and food grains in semi-arid regions. In th...
Panicle exsertion (PE) is an important morphological trait that is closely associated with spikelet fertility and grain yield. To understand the genetic basis of PE and its relationships with yield and yield-related traits, a recombinant inbred population consisting of 240 lines derived from a cross between an Indica cultivar 'Kasalath' and a Japonica germplasm 'TD70', was studied over two year...
Tillering and secondary stems in graminea plants are permanent characters, whereas there were being food matters and proper temperature for regeneration. Ratooning or regeneration phase is explained to remain of plant for growing in next season. Recombinant inbred lines (RILs) consisting of 80 lines, derived from a cross between Hashemi and Nemat were used to analyze the genetic basis ratooning...
Panicle traits are among the most important agronomic characters which directly relate to yield in rice. Grain number (GN), panicle length (PL), primary branch number (PBN), and secondary branch number (SBN) are the major components of rice panicle structure, and are all controlled by quantitative trait loci (QTLs). In our research, four advanced backcross overlapping populations (BIL152, BIL19...
Rice is one the most important crops in Iran and worldwide. Abiotic stresses including drought, restrict rice production. In order to saturation of linkage map in recombinant lines population caused by Sepidroud × Anbarbou crosses, an experiment was conducted using 96 recombinant lines and 40 ISSR markers at Gonbad Kavous University. 96 Recombinant lines were plant under hydroponic condit...
Pearl millet [Pennisetum glaucum (L.) R. Br.] is a staple crop for the people of arid and semi-arid regions of the world. It is fast gaining importance as a climate resilient nutricereal. Exploiting the bold seeded, semi-dwarf, and early flowering genotypes in pearl millet is a key breeding strategy to enhance yield, adaptability, and for adequate food in resource-poor zones. Genetic variation ...
Time-related mapping of quantitative trait loci controlling grain-filling in rice (Oryza sativa L.).
Grain-filling is a crucial process that determines final grain yield in rice (Oryza sativa L.). To understand the genetic basis of dynamics of grain-filling, quantitative trait locus (QTL) analysis was conducted using time-related phenotypic data on grain-filling collected from a population of 155 recombinant inbred lines (F12), derived from a cross between Milyang 23 and Akihikari. Two QTLs de...
Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
To identify the genes responsible for yield related traits, and heterosis, massively parallel signature sequencing (MPSS) libraries were constructed from leaves, roots and meristem tissues from the two parents, 'Nipponbare' and '93-11', and their F1 hybrid. From the MPSS libraries, 1-3 million signatures were obtained. Using cluster analysis, commonly and specifically expressed genes in the par...
this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...
