High grain protein content (GPC) is a frequent target of wheat breeding programmes because of its positive effect on bread and pasta quality. A wild wheat allele at the Gpc-B1 locus with a significant impact on this trait was identified previously. The precise mapping of several senescence-related traits in a set of tetraploid recombinant substitution lines (RSLs) segregating for Gpc-B1 is repo...

The shape of the rice flag leaf affects yield. Therefore, detection quantitative trait loci (QTLs) and alleles related to is great significance for yield improvement. in 2019 2020, we carried out a genome-wide association study length (FLL), width (FLW), length–width ratio (FLR), area (FLA), considering 1.3 million single-nucleotide polymorphisms (SNPs) 173 accessions, order investigate effects...

To evaluate the effects of O3 on the net photosynthetic rate in flag leaves of rice (Oryza sativa L.) based on stomatal O3 flux and reactive oxygen species (ROS) scavenging enzyme activities, the Japanese rice cultivar Koshihikari was exposed to O3 for 1 month after heading in O3-exposure chambers. During the exposure period, rice plants were exposed to charcoal-filtered air or O3 at 60 or 100 ...

The grain yield of pearl millet has increased continuously in past decades through development hybrids and improved production practices. Elite inbred lines are crucial for innovating new germplasm/traits to break the plateau. Hence, 64 were evaluated assess extent genetic variability association among agronomic, physiological contributing traits. Analysis variance showed significant difference...

abstract this research was conducted in toroq experimental field station, mashhad, iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. moisture stress treatments (at seven levels) were assigned to main plots, including: d1 ( full irrigation), d2 (no irrigation from one-leaf to double ridge) stag...

The aim of this research was to identify the vegetative and generative characters G16 rice mutants due gamma-ray irradiation. experiment conducted in Saribaye Village, Lingsar District, West Lombok Regency. experimental design used an Augmented Design, using three comparison plants, namely line (parent), Inpago Unram 1 variety, IPB 3S variety. four mutant populations tested were doses 200, 300,...

Video resolution can be improved when a group of corresponding frames from two or three videos are registered, which are taken by two or three camcorders with fixed focus length and position. An efficient algorithm for constructing high quality video from videos is proposed. In order to reduce registration errors, we apply a gradient descent algorithm to the matching images, which results in an...

Rice germplasm investigated as completely randomized design under flooding and deficit irrigation conditions. The results of the association analysis indicated that RM29, RM63, RM53 could be used for rice breeding programs to improve yields irrigation. highest accuracy performance prediction was 98.36 RFA (RFA) panicle length, flag leaf width, number primary branches, after that, MLP algorithm ...

Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...
