in order to assess the heritability of short vegetation period (early maturity) of sugar beet hybrids, an experiment was carried out in randomized complete block (rcb) design with 4 replications in abdolrasoul motahari agricaltural research station of sugar beet seed institute, karaj, iran in 2009. in this research, the heredity of the traits in testcrosses derived from crosses of 18 half sib f...

Compared with morphological and life history traits, quantitative genetic variation of metabolic and related traits in animals has been poorly studied. We used flow-through VCO(2) respirometry and simultaneous activity measurement on nymphs of the sand cricket (Gryllus firmus) from inbred lines to estimate broad-sense heritability of four metabolic variables. In addition, we measured a number o...

The narrow-sense heritability and expected selection response are very important to be recognized in the F2 population of maize determine character selected. This study aimed estimate narrow-senseheritability quantitative characters population. experimental method used this was field experiments on dry land using pumping wells for irrigation. conducted from April October 2022 Amor-Amor Hamlet, ...

Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

Genetic improvement of seed vigour and emergence of yellow-seeded flax (Linum usitatissimum L.) is important to have a good stand establishment, since they are negatively affected by yellow seed colour. This study was conducted to investigate genetic variation, broad-sense heritability and expected genetic response to selection for germination, seed vigour and field emergence. Sixteen genotypes...

Abstract To evaluate the relationships among clones and open pollinated families from same plus trees to select elite breeding materials, growth, wood characteristics of 33-year-old Pinus koraiensis were measured analyzed. The results show that growth characters varied significantly. variation due clonal effects was higher than family effects. ratio genetic phenotypic coefficient in traits abov...
