Iran is a part of the secondary center of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. In this work, 14 morphological traits were studied in order to select the most discriminating traits. Significant difference among accessions was revealed for almost quantitative traits. KMO coefficient obtained was 0.723 that is explaining of appropriation of this test. The results of the principal component analysis (PCA) for the morphological traits indicated that the first three PCs explained 53.46% of the total variation. Principal component analysis results (PCA) for morphometric data indicated that samples of Semnan and Khorasan showed high degree of  variation and were hi

A project to develop new maize (Zea mays L.) inbreds from inbred populations, crossed, and tested for performance. The project elapsed six seasons, 3 spring and 3 full plantings during 2015-2017. Newly developed inbreds showed significant grain yield increase as compared to the cross of its progenitor inbred. An increase of 2 t ha^-1 was obtained with one of the new inbreds. The crosses obtained were evaluated in field trials with a registered hybrid (60×21). Method of selection counts on a unique plant trait in the inbred population, such as longer ear, thicker ear diameter, stay-green leaves, large kernel, and so on. The merit obtained due to hybrid vigor could be attributed to parental inbreds that have hig

Field experiment was conducted at field of Fallujah- Anbar Governorate/ Iraq, during the two seasons of 2017. Seeds of eight maize inbred lines were cultivated, and line × tester method was used to produce 16 crosses. The seeds of parents were cultivated and crosses in the fall season of 2017 in a randomized complete block design with three replicates. The objectives of the study were to estimate gene action, hybrid vigour, and the effects of general and specific combination abilities of the inbred lines  and to evaluate test cross performance of the hybrids for grain yields and yield related traits. There were significant differences between parents and their crosses for all studied traits. The results showed that crosses

The certain crop cultivars could be adapted that characterized their performance via given trait over given environments. Thus this adaptation could be investigate by many methods. Therefore, ternary plot method advocated to assess the adaptation of ten caraway cultivars using seed yield (Mg ha^-1) over two environments viz. Fallujah and Ramadi for two successive seasons (2011/2012 and 2012/2013). This method was fortified with AMMI Biplot technique. PAST software was adopted to construct triangle graph. Cropstat7.2 software was also applied to extract cultivars own biplots. Results from ternary plot showed that G7 was the both most adaptable cultivars over most circumstances, G3 irresponded because it located on point
