Dry root rot (DRR) caused by Rhizoctonia bataticola [(Taub.) Butler] is an emerging disease of chickpea (Cicer arietinum L.) and a serious constraint to production in warm arid regions. To identify the genomic regions conferring resistance DRR, total 182 F9 derived Recombinant Inbred Lines (RILs) were developed from cross between susceptible line BG 212 moderately resistant breeding ICCV 08305....

The objective of this study was to evaluate boron tolerance wheat genotypes using mature embryo culture. analysis involved 79 recombinant inbred lines the International Triticeae Mapping Initiative (ITMI) population and three Serbian varieties with known (B) (Pobeda - sensitive S, Balerina-medium tolerant MT, Nevesinjka T). evaluation performed on a modified MS medium which 15 mM boric acid add...

We consider fixed recombinant inbred lines (RILs) derived either by selfing or by full-sib mating; when applicable, we also consider intermated recombinant inbreds (IRIs). First, we show that the usual estimate of recombination fraction based on RIL data is biased, and we provide an estimate where the major part of that bias is removed. Second, we derive simple formulas to compute the frequenci...

The Collaborative Cross (CC) is a multiparental recombinant inbred panel derived from eight laboratory mouse inbred strains. Breeding of the CC lines was initiated with mice from The Jackson Laboratory at multiple international sites. Currently, we are breeding independent CC lines at the University of North Carolina (UNC), at Tel Aviv University (TAU) and at Geniad in Western Australia (GND). ...

Aryl hydrocarbon (benzo[a]pyrene) hydroxylase inducibility by benzo[a]anthracene was studied in 29 somatic cell hybrid clones, developed by fusing mouse spleen or peritoneal cells from four different inbred strains with hypoxanthine phosphoribosyltransferase-deficient Chinese hamster E36 cells. Karyotype analysis plus 25 markers assigned to 16 autosomes and the X chromosome were examined. In 28...

In a line or a hybrid breeding program superior lines are selected from a breeding pool as parental lines for the next breeding cycle. From a cross of two parental lines, new lines are derived by single-seed descent (SSD) or doubled haploid (DH) technology. However, not all possible crosses between the parental lines can be carried out due to limited resources. Our objectives were to present fo...
