in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...
Breeding for environmental stress is one of the most important goals in plant breeding. Among stresses, drought stress has high influencing on limitation of maize production. Therefore, in order to find the best drought tolerant hybrids, 38 maize hybrids were planted in two separate experiments: one with optimum irrigation (control) and another with water stress at grain-filling stage in Moghan...
Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability. Determining of the combining ability and genetic variance components is one of the most important stage in breeding program of maize inbred lines. For this purpose, the number of 25 early maturity lines with two testers (k1263/1 early and late A679) crossed...
samples with stalk rot, yellowing and stunting symptoms from maize fields in western provinces of iran were collected. after cultured of them on eosin methylen blue (emb) medium, twenty bacterial strains with metallic green color colonies on emb medium were selected for identification tests. according to the biochemical and phenotypic characteristics, these strains were identified as dickeya ze...
Salinity stress is one of the most important abiotic stresses that effects on many agronomic, nutritional, physiological and biochemical processes of crops. A factorial experiment based on completely randomize design with four replications under laboratory conditions with four maize hybrids (SC640, SC704, SC740 and SC Simon) and three levels of salt stress (0, 100 and 200 mM NaCl) was carr...
Two field experiments were conducted in 1995-1996 to determine if there are common yield responses among maize hybrids to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. Three yellow dent hybrids, five white food grade dent hybrids, and a popcorn hybrid were included in the study. The minimum level of rootworm injury as measured by root damage ratings (3.2-4.2) that...
in order to study drought tolerance indices and to introduce tolerant maize hybrids in drought conditions, an experiment was conducted at the experimental field of seed and plant improvement institute, in 2009. the experiment was carried out using split-plot in a randomized complete block design (crbd) with three replications. the main plots consisted of three levels of irrigation regimes (irri...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
To facilitate the interpretation of data from a genotype by environment experiment (GE), a cluster method is proposed to group genotypics according to their response to the environments especially when the GE interaction is large. The interaction structure of two-way classification data often can be identified if the data stratified into homogeneous subsets. In this paper four GE interaction cl...
ABSTRACT Measures of epistasis in maize hybrids have been estimated by (i) triple-test crosses, (ii) making comparisons Certain maize (Zea mays L.) inbred lines are more successful than of single, three-way, and double cross hybrids, or (iii) others in forming elite hybrids. This study was conducted to determine measuring variance components (Hallauer and Miwhether epistatic interactions play a...
