Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
since crosses of lines with suitable genetic distance produce excellent hybrids, the identification of genetic diversity between zea mays l. inbred lines in hybrid maize breeding programs has a high priority. a total of 27 inbred lines plus b73 and mo17 (sc704 parents) were evaluated by 15 inter-simple sequence repeat (issr) primers. inbreds were selected randomly from inbred lines from the agr...
Non-additive gene regulation has been recently suggested as an important factor promoting phenotypic variation and plasticity. In order to obtain a description of gene expression status at an early stage of ear development in a maize (Zea mays L.) F1 hybrid as relative to its parental inbreds, we compared gene expression profiles in immature ears of elite inbred lines B73 and H99 to one of thei...
Two lines of Zea mays were developed as a short-generation model for maize. The Fast-Flowering Mini-Maize (FFMM) lines A and B are robust inbred lines with a significantly shorter generation time, much smaller stature, and better greenhouse adaptation than traditional maize varieties. Five generations a year are typical. FFMM is the result of a modified double-cross hybrid between four fast-flo...
Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
Centromere positions on 7 maize chromosomes were compared on the basis of data from 4 to 6 mapping techniques per chromosome. Centromere positions were first located relative to molecular markers by means of radiation hybrid lines and centric fission lines recovered from oat-maize chromosome addition lines. These centromere positions were then compared with new data from centric fission lines r...
To evaluate the effect of nitrogen sources on yield and quality of sweet basil and forage maize under intercropping (additive series), a field experiment was carried out at the experimental field of faculty of agriculture, Lorestan University, Khorramabad, Iran, in 2013-2014 and 2014-2015 growing seasons. Experimental treatments were arranged as factorial in randomized complete block design wit...
* Corresponding author Maize (2n = 40) x Tripsacum dactyloides (2n = 72) F1 hybrid plants (2n = 56) were obtained by embryo rescue and induction of somatic embryogenesis/organogenesis. Hybrid plants showed Tripsacum-like phenotypes, tolerance to stresses such as NaCl salinity and low temperatures. The more frequent meiotic configurations were 28 II (24%), 24 II + 2 IV (19%) and 26 II + 1 IV (12...
In order to study agronomic and morphological traits in maize hybrids in Hammedan, two early (108 and 301), three medium (604, 647 and TWC647) and two late maturing (704 and 711) hybrids were evaluated in a randomized complete block design with three replications in Agricultural and Natural Resources Research Station in Hammedan in 2005. 33 morphological and phonological traits were recorded fr...
Flow sorting maize chromosome 1 and construction of the first chromosome 1 DNA Lambda library are described. Maize metaphase chromosome suspensions were prepared from synchronized seedling root tip cells of the maize hybrid line Seneca 60 and stained with propidium iodide for flow karyotyping and sorting. The observed flow karyotype was very similar to the predicted flow karyotype constructed b...
