in order to evaluate of diversity among new maize hybrids for quantitative and morphological traits, 17 new single cross maize hybrids were studied in shahrood agriculture research station using randomized complete blocks design with four replications. results showed that five independent factors were responsible for significant correlation between 16 measured traits and explained 89.18% of tot...
Sexual reproduction in plants requires development of haploid gametophytes from somatic tissues. Pollen is the male gametophyte and develops within the stamen; defects in the somatic tissues of the stamen and in the male gametophyte itself can result in male sterility. The maize fuzzy tassel (fzt) mutant has a mutation in dicer-like1 (dcl1), which encodes a key enzyme required for microRNA (miR...
spot, has been observed causing severe damage in all maizegrowing areas of Brazil since 1982 (Fantin, 1994). The causal organism of this disease was initially described in the USA as Phaeosphaeria maydis (Henn.) Rane, Payak & Renfro (sin. Sphaerulinia maydis Henn.), anamorph Phyllosticta sp. (Rane et al., 1966). Doubts regarding the etiology of this disease have resulted in several attempts to ...
The heading stage of rice is a critical period for disease control, such as panicle blast. rapid and accurate monitoring growth great significance plant protection operations in large areas mobilizing resources. For this paper, the canopy multispectral information acquired continuously by an unmanned aerial vehicle (UAV) was used to obtain rate inversion. results indicated that multi-vegetation...
Orchardgrass (Dactylis glomerata L.), is a well-known perennial forage species; however, rust diseases have caused a noticeable reduction in the quality and production of orchardgrass. In this study, genetic diversity was assessed and the marker-trait associations for rust were examined using 18 EST-SSR and 21 SCoT markers in 75 orchardgrass accessions. A high level of genetic diversity was det...
Abstract Morphological and phenological variability of Guaraní maize germplasm from Northeastern Argentina (NEA) are potential sources genetic resources, constituting valuable repositories alleles associated with tolerance resistance to biotic abiotic stresses. Here, we studied the morphological in populations 14 landraces NEA analysed relationship among them. These were characterised according...
