In order to evaluate phenologic and thermal time response of three maize hybrids (KSC 704, Maxima and TWC 604) in different rates of nitrogen (0, 92, 220 and 368 kg ha-1), a two-year experiment was laid out as a randomized complete block design with a factorial arrangement of treatments and three replications in 2014 and 2015. Results showed that nitrogen and genotype had a significant effect (...
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...
There has been some concern about using small seeds that may result from seed position on the ear or poor growing conditions for seeding hybrid maize. This study was designed to investigate the effect of seeding three commercial maize crosses (Single Cross 2010, Three-Way Cross 310 and Three-Way Cross 321) with three seed sizes (large, medium and small) under seven salinity levels of irrigation...
This experiment was conducted to study the effects of water deficit stress on morphological traits, yield and yield components of 60 maize single cross hybrids at Torough Agricultural and Natural Resources Research C enter located in Mashhad, Iran on 2013. This experiment was laid out in randomized complete block design with three replications. The irrigation treatments were consisted of two ...
A study was conducted to assess the performance of maize hybrids with Bt event MON810 (Bt-hybrids) against the maize stem borer Busseola fusca (Fuller) in a biosafety greenhouse (BGH) and against the spotted stem borer Chilo partellus (Swinhoe) under confined field trials (CFT) in Kenya for three seasons during 2013-2014. The study comprised 14 non-commercialized hybrids (seven pairs of near-is...
Drought stress is the most important limiting factor in crop plants including maize (Zea mays L.), which is the third important world crop after wheat and rice. Water deficiency at different growth stages affects maize yield differently. To examine the response of four maize hybrids to drought stress at different growth stages, a field experiment was carried out as a split plot based on complet...
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...
Recombination distances and linkage heterogeneity were compared among a wide range of maize inbreds, wide crosses and maize x teosinte hybrids. Twelve maize and four teosinte races were backcrossed to stocks fixed for rare marker alleles on chromosome arm 1L. Recombination fraction estimates were higher for exotic germplasm than for either U.S. maize or maize x teosinte crosses. Serrano, Tuxpeñ...
In order to identify the most important traits affecting yield in maize inbred lines and hybrids, an experiment was conducted in Shushtar City in 2009 and 2010 years. Fifteen inbred lines in 2009 and 28 hybrids in 2010 studied in two planting dates, 6 July (to coincide heat stress with pollination time and grain filling) and 27 July (normal condition) using a randomized complete block design wi...
