In order to study the heritability and genetic parameters of antioxidant activity in barely (Hordeum vulgare L.) under salinity stress, a seven-parent half diallel (F1 crosses + parents) was conducted non-stress salt stress (8 12 dS m-1) conditions greenhouse, during 2016-17, Ardabil, Iran. this experiment, enzymes ascorbate peroxidase (APX), catalase (CAT) superoxide dismutase (SOD) were measu...
STUDY OF THE GENETIC DIVERSITY OF SOME GENOTYPES OF MAIZE UNDER TWO LEVELS OF NITROGEN FERTILIZATION
The present study aimed to determine the genetic divergence of seven maize genotypes (Al-Maha, Sumer, Al-Fajr, Baghdad, 5018, 4 × 1 single hybrid, and 2 hybrid) under two varied levels nitrogen fertilization (92 276 kg N ha-1). experiment occurred in 2022 a randomized complete block design (RCBD) with split-plot arrangement three replications at College Agricultural Engineering Sciences, Univer...
Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] production in the United States has, in the past few years, incurred significant losses to races 1W and 2WU.S. powdery mildew (Podosphaera xanthii) infection. We report the mode of inheritance, gene action, and heritability of race 2WU.S. resistance in two populations derived from a cross involving the resistant genotype pI 189225 and the ...
Characterization and conservation of germplasm is a critical step toward the genetic improvement crop. This study assessed variation in 257 common bean genotypes which included 207 accessions obtained National Gene Bank Kenya, 33 from Kenya Agricultural Livestock Research Organization (KALRO), 13 landraces collected farmers’ fields four commercial varieties for various agronomic traits. T...
apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
BACKGROUND Optic nerve head (ONH) and surrounding structures such as β-zone peripapillary atrophy (PPA) are important structures in glaucomatous pathogenesis. Thus, for understanding genetic components in glaucoma pathogenesis, it is necessary to evaluate the heritability of ONH and surrounding structures. The present study investigated the genetic influences on ONH and surrounding structures s...
UNLABELLED BACKGROUND Autism spectrum disorders (ASD) are early onset neurodevelopmental syndromes typified by impairments in reciprocal social interaction and communication, accompanied by restricted and repetitive behaviors. While rare and especially de novo genetic variation are known to affect liability, whether common genetic polymorphism plays a substantial role is an open question and...
hande, 1957; Nyquist, 1991). This approach is based on the assumption that both random and systematic Inexpensive estimates of broad-sense heritability (BSH) may be environmental variation within a planting containing a valuable in plant breeding. This research evaluated two methods for estimating BSH with data from stands of equidistantly spaced genosingle genotype follows an inverse logarithm...
