In a breeding effort to develop salt tolerant (ST) rice varieties by designed QTL pyramiding, large numbers of progenies derived from four crosses between salt- or drought- tolerant BC2F5 IR64 introgression lines, were subjected to severe salt stress, resulting in 422 ST plants. The progeny testing of the selected F3 lines under more severe salt stress resulted in identification of 16 promising...

A chlorophyll deficiency expressed as yellowing of leaves was observed in hazelnut (Corylus avellana L.) progenies. Segregation ratios approximated 3 green : 1 yellow, indicating control by a single recessive gene designated chlorophyll deficient #1, for which the symbol c, is proposed. ‘Barcelona’, ‘Butler’, ‘Compton’, ‘Lansing’, Willamette’, and the ornamental selection ‘Redleaf #3’ are heter...

OBJECTIVES Extreme hyperbilirubinemia (plasma bilirubin ≥ 24.5 mg/dL) is an important risk factor for severe bilirubin encephalopathy. Several risk factors for hyperbilirubinemia are known, but in a large number of patients, a causal factor is never established. UGT1A1 is the rate-limiting enzyme in bilirubin's metabolism. The genotype of Gilbert syndrome, the UGT1A1*28 allele, causes markedly ...

Part of the success a breeding program depends on composition base population. Superior genotypes and unimproved dioecious varieties are sources genes for traits interest excellent options formation segregating populations. Here we describe first cycle recurrent selection (RS) in papaya propose an effective strategy, unprecedented crop, to generate variability new cultivars. Initially, RS popul...

background & aim: low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. several studies has conducted to recognize the risk factors of lbp, but despite of strong relationship between obesity and lbp, the underlying mechanisms are unclear. the aim of this study was to evaluate the relationship betwe...

abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...

Assessing the parental genetic differences and their subsequent prediction of progeny performance is an important first step to assure the efficiency of any breeding program. In this study, we estimate the genetic divergence in Eucalyptus camaldulensis based on the morphological traits of 132 progenies grown in a savanna biome. Thus, a field experiment was performed using a randomized block des...

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

N previous communications (MALOGOLOWKIN and POULSON 1957; MALOGOI LOWKIN 1958) a cytoplasmically inherited sex-ratio condition has been described in Drosophila willistoni and in D. paulistorum. In both species, certain females produce progenies consisting mostly or only of daughters. This capacity for the production of unisexual broods is inherited by their entire female progenies and is not tr...

building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
