Information regarding the adaptation of maize (Zea mays L .) inbred lines to various field conditions and seed longevity is essential for companies. The objective this work was evaluate different vigour tests detecting differences among naturally aged seeds assess relationship between quality parameters pedigree data lines. A 15 lines, selected at Maize Research Institute Zemun Polje, belonging...

Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...

abstract- maize production, which is ranked after wheat and barely in fars province, iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. therefore, proper planting method can improve irrigation water management. the objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...

Maize (Zea mays L) is the most important food grain in sub-Saharan Africa and is mostly grown by small-scale farmers under rainfed conditions. Aluminum toxicity caused by low pH is one of the abiotic factors limiting maize production among smallholder farmers. Therefore, breeding maize hybrids that are tolerant to aluminum toxicity will sustain and increase maize production in these areas. Henc...

Combining ability, gene action and heterosis was studied for no. of days to 50% tasseling, no. of days to 50% silking, flag leaf area, plant height, no. of rows/ear, no. of grains/row, 300-grain weight and grain yield/plant in a Factorial Mating in Randomized Completely Randomized Design conducted separately in spring and autumn sowing dates, 2013 through hybridization between three parents of ...

An experiment was conducted at Al- Hamidhia Research Fields, Faculty of Agriculture / Anbar University in North Ramadi city to study the levels salicylic acid 0, 200 and 400 mg. L-1 fifteen genotypes (5 inbred lines + 10 hybrids) maize. A randomized complete block design used a slit table arrangement; thus, main treatments are for spray, secondary tables (inbred hybrids). Three replications wer...

Many commercial inbred lines are available in crops. A large amount of genetic variation is preserved among these lines. The genealogical history of the inbred lines is usually well documented. However, quantitative trait loci (QTL) responsible for the genetic variances among the lines are largely unexplored due to lack of statistical methods. In this study, we show that the pedigree informatio...

the choice of an efficient breeding procedure depends to a large extent on knowledge of the genetic system controlling the character to be selected. the objective of this study was to determine genetic parameters for yield and other traits including some of the yield components under three planting densities, using analysis of generation means (p1, p2, f1, f2, bc1 and bc2) derived from crosses ...
