Breeders often use generation means analysis to obtain information about inheritance, gene action, and to determine effective breeding methods to improve important agronomic traits, especially under drought stress conditions. To investigate the genetic parameters of agronomic and morphological traits in durum wheat, a field experiment was carried out using F1, F2, BC1 and BC2 generations obtain...
Andrographolides, the diterpene lactones, are major bioactive phytochemicals which could be found in different parts of the medicinal herb Andrographis paniculata. A number of such compounds namely andrographolide (AG), neoandrographolide (NAG), and 14-deoxy-11,12-didehydroandrographolide (DDAG) have already attracted a great deal of attention due to their potential therapeutic effects in hard-...
Diallel analysis was used to estimate the combining ability, gene action, gene number, heritabilties and other genetic parameters of a set of wheat genotypes. For this purpose, nine parents and their 36 crosses were evaluated for 9 traits in a randomized complete block design with three replications in 1996. The analysis of variance revealed significant differences among all genotypes for all ...

inheritance of cold resistance and estimation of genetic parameters in rice at the germination stage
the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...
Common beans are an important nutritious food crop to many people in developing countries. Inadequate soil-P is one of the major constraints high bean seed yield productivity. Information about genetic effects that control inheritance root traits common grown under low conditions scarce, and a challenge for enhancement. This study was therefore implemented determine gene action tolerance soil-P...
Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....
Four advanced breeding lines of wheat which had appeared to be resistant to stripe rust in the past years along with a susceptible variety, Bolani, were intercrossed in all combinations of a half-diallel design. Seedlings were grown in greenhouse until the first leaves fully expanded and then inoculated with two pathotypes (races) 6E134A+ and 134E148A+, separately. Days to the first pustule eru...
to estimate combining ability and the model of gene action for some quantitative characters, 5 different rice genotypes were used for producing a half diallel hybrids. to consider 7 quantitative traits, hybrids and their corresponding parents were evaluated based on a randomized complete block design with three replications at the rice research station of amol, iran in 2007. mean squares regard...
Five wheat varieties were used to estimate gene action for morphological traits and yield and estimate the heritability of traits. The varieties including White Bolani, Brown Bolani, Tajan, Kealk and AS48 mutant have been crossed based on full diallel. The F2 genotypes were planted in a randomized complete block design with three replications in the Nuclear Agricultural Research Institute. Anal...
