the russian wheat aphid (rwa), diuraphis noxia (mordvilko), is a significant insect pest of wheat worldwide. the objective of this study was to assess the genetic variation within and between f2-derived families for reaction to rwa using f3 and f4 families originating from individual f2 plants of a cross between the susceptible line (synthetic hexaploid-11) and the resistance cultivar (‘halt’)....

Behavioral traits generally show moderate to strong genetic influence, with heritability estimates of around 50%. Some recent research has suggested that trust may be an exception because it is more strongly influenced by social interactions. In a sample of over 7,000 adolescent twins from the United Kingdom's Twins Early Development Study, we found broad sense heritability estimates of 57% for...

Sugarcane is one of the important cash crops for Pakistan and it has been primary source sugar production. used in our mills it’s by products are making cattle feed, soil manure etc. Present research experiment was conducted to assess 32 genotypes sugarcane collected from different farms cane yield through contributing traits natural field conditions. Traits like Cane height, girth, area leaf...

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...

salinity is one of the abiotic stresses and exploitation of heterosis could increase the crop yield and extend the stress tolerance, especially in salinity stress. in this research, a set of full diallel design involving 7×7 crosses from cultivars including flat, bam, ghods, roshan, arg, kavir and pishtaz were conducted in a randomized complete block design with three replications under both no...

A diallel cross from seven parents and their F1 hybrids were evaluated across three locations using a Randomized complete block design with replications for quantitative traits performance. Parameters assessed include plant heights, days to 50% headings, panicle lengths, weights, number of seeds per panicle, productive tillers, branches, yield plots which extrapolated in tonnes hectare 100 grai...
