insulin-like growth factor-1 gene (igf1) is a biological candidate gene for investigation traits such as growth, body weight and muscles growth in different species. in this research eight pairs of white and wild quails were crossed reciprocally as a base population. a total of 34 quails were produced in first generation (f1) and 422 quails were generated by intercrossing the f1 population. bod...

The pre weaning growth performance of piglets from four different cross bred dams mated back to their native parents was studied in the Breeding and Research Farm Ebonyi State University, Abakaliki. Parameters like body weight, weight gain, feed intake efficiency as well linear measurements length, heart girth height at withers were taken observed for between birth age eight weeks. Results indi...

the objective of this experiment was to investigate inheritance and gene action for resistance to sunn pest (eurygaster integriceps) and related traits in bread wheat including f1, f2 and backcross generations derived from a cross between line 15 as resistance and line 12 as susceptible parents. parents along with f1, f2, bc1 and bc2 generations were evaluated in a randomized complete block des...

Abstract The aim of the present study was to identify grape parent varieties that lead greater frequency seedless genotypes in progenies and understand relationships between trait other fruit traits. A group 200 hybrids (F1) originating from 38 crosses among cultivars Vitis vinifera L. interspecific were evaluated Juazeiro, Bahia, Brazil, over six consecutive crop seasons (2018 2021). placed th...

eight pollinators (as pollen parents) and four cms lines (as seed parents) differing in salinity and drought tolerance were evaluated using agro-morphological traits and microsatellite markers. root yield, leaf weight, sugar content, sodium content (na+), potassium content (k+), a-amino nitrogen content, alkalinity coefficient, molasses sugar, white sugar content, extraction coefficient of suga...

Crosses between Betula nana and B. utilis 'Doorenbos' were undertaken in order to obtain interspecific hybrids which could be characterized by wide spreading stems, strong branching habit, decorative clear white bark and an interesting shape of purple leaves. The research purpose was to examine genetic diversity of the 16 F1 and F2 putative progenies by using the RAPD-PCR method and the ploidy ...
