A previous study on maize F(2:3) families derived from Lo964xLo1016 highlighted one QTL in bin 1.06 (hereafter named root-yield-1.06) affecting root and agronomic traits of plants grown in well-watered (WW) and water-stressed (WS) conditions. Starting from different F(4) families, two pairs of near isogenic lines (NILs) were developed at root-yield-1.06. The objective of this study was to evalu...
BACKGROUND AND AIMS Root traits can be selected for crop improvement. Techniques such as soil excavations can be used to screen root traits in the field, but are limited to genotypes that are well-adapted to field conditions. The aim of this study was to compare a low-cost, high-throughput root phenotyping (HTP) technique in a controlled environment with field performance, using oilseed rape (O...
Future rice (Oryza sativa) crops will likely experience a range of growth conditions, and root architectural plasticity will be an important characteristic to confer adaptability across variable environments. In this study, the relationship between root architectural plasticity and adaptability (i.e. yield stability) was evaluated in two traditional × improved rice populations (Aus 276 × MTU101...
Future rice (Oryza sativa) crops will likely experience a range of growth conditions, and root architectural plasticity will be an important characteristic to confer adaptability across variable environments. In this study, the relationship between root architectural plasticity and adaptability (i.e. yield stability) was evaluated in two traditional 3 improved rice populations (Aus 276 3 MTU101...
in order to evaluate the effect of some qualitative traits of sugar beet (beta vulgaris l.) under irrigation water quality and different types of fertilizers, a field experiment arranged as split plot in rcbd design with three replications at research station of shahrekord university in 2013. the main factor include irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigat...
in order to investigate the effects of plant growth promoting rhizobacteria (pgprs) inoculation on the growth, yield and quality of eesetial oils of summer savory (satureja hortensis l .) a pot experiment based on randomized complete block design with three replication were conducted in field of research institute of forests and rangelands at 2012. bacterial treatments include suspension of thr...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
To study yield, yield component and some morphological traits in cotton, six parents with 15 hybrids (totally 21 genotypes) were evaluated using a randomized complete block design with three replications at a salty farm Bandar Torkaman area in 2005. Nine traits were measured including the percentage of germination, plant height, number of monopodial branches, length of monopodial branches, numb...
study on genetic variation in safflower collection (carthamus tinctorius l.) under rainfed condition
safflower is an oilseed crop with high adaptability to rainfed conditions of iran. it is native crop in iran and due to some morphological characters specially root system it shows good resistance to drought stress. in present investigation to study genetic variation in fall planting of safflower in rainfed condition 100 genotypes were evaluated in a 10×10 simple lattice square design with two ...
Reducing water requirements and lowering environmental footprints require attention to minimize risks to food security. The present study was conducted with the aim to identify appropriate root traits enhancing rice grain yield under alternate wetting and drying conditions (AWD) and identify stable, high-yielding genotypes better suited to the AWD across variable ecosystems. Advanced breeding l...
