Pedigree reconstruction using molecular markers enables efficient management of inbreeding in open-pollinated breeding strategies, replacing expensive and time-consuming controlled pollination. This is particularly useful in preferentially outcrossed, insect pollinated Eucalypts known to suffer considerable inbreeding depression from related matings. A single nucleotide polymorphism (SNP) marke...

Records of five inbred lines at the Livestock and Range Research Laboratory were used to evaluate effects of inbreeding and heterozygosity on preweaning traits. Members of each line were descendants of a single founder Hereford bull. A total of 8,065 records of birth weight and 7,380 records of preweaning daily gain and weaning weight were analyzed by derivative-free REML using a model that inc...

blast (magnaporthe grisea) is the most important disease of rice in mazandaran province, north of iran, which causes severe damages annually on susceptible cultivars. tarom mahalli is a local aromatic cultivar with high cooking quality and marketability, but very susceptible to blast. to protect this cultivar and similar susceptible cultivars against rice blast, farmers have to use high amounts...

The present study was performed to study the effect of inbreeding on the pre-weaning growth traits including the birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and lamb survival from birth to weaning (SUR) in Baluchi, Iran-Black and Zandi sheep. Significant positive inbreeding trends were found only for Baluchi and Iran-Black breeds as 0.038 and 0.278, resp...

Inbreeding adversely affects life history traits as well as various other fitness-related traits, but its effect on cognitive traits remains largely unexplored, despite their importance to fitness of many animals under natural conditions. We studied the effects of inbreeding on aversive learning (avoidance of an odour previously associated with mechanical shock) in multiple inbred lines of Dros...

In the present study, three sets of F4 progeny lines developed through different cycles pollen selection for heat tolerance were studied genetic differences using 16 SSR markers during 2017–20 at Department Plant Biotechnology, University Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru, Karnataka. Three groups progenies used study are GGG (pollen in F1, F2 and F3 generation); GCG...

LTHOUGH close inbreeding does divide a population up into lines, members A of which are in general very similar-wRIGHT claims there was never any difficulty in telling to which of his 23 lines of inbred guinea pigs any individual guinea pig belonged-it has often been observed that some characters in some lines become more variable with inbreeding. The characters for which this has been found to...

While the genetic consequences of inbreeding and small population size are of fundamental importance in many areas of biology, empirical research on these phenomena has proceeded in the absence of a well-developed statistical methodology. The usual approach is to compare observed means and variances with the expectations of Wright's neutral, additive genetic model for quantitative characters. I...

Abstract Euterpe precatoria is a Neotropical palm from South and Central America hyperdominant in Amazonia, where it increasingly important the Brazilian market for açaí. Genetic diversity, population structure mating system of E. were characterized with 10 microsatellite markers three localities (Codajás, Manacapuru, Manaquiri) along lower Solimões River, Amazonas, Brazil. Leaves 63 mature pal...

In chickpea a multi-parent advanced generation intercross (MAGIC) population was developed using eight parents that are improved varieties and widely adaptable breeding lines. The main objective to enhance the genetic diversity bring novel alleles for developing superior varieties. development scheme involved sequence of 28 two-way, 14 four-way 7 eight-way crosses, followed by bulking final F1 ...
