Postweaning, feedlot, and carcass data from crossbred calves sired by five Bos indicus breeds and one Bos taurus breed were evaluated. Data included records from F1 calves out of multiparous Hereford cows sired by Angus, Gray Brahman, Gir, Indu-Brazil, Nellore, and Red Brahman bulls. The Zebu crosses grew faster postweaning and were heavier and taller as yearlings than the Angus crosses (P < .0...

Specific crosses resulting in 305 litters sired by Duroc, Spot or Hampshire boars out of Landrace, Duroc-Landrace or YorkshireLandrace sows were evaluated for preweaning and postweaning performance. Duroc-sired litters were heavier (P<.05) at 21 days postfarrowing than Spotor Hampshiresired litters. Hampshire-sired litters were heavier (P<.05) at birth than Spot-s i red litters. Litters from cr...

Generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[Sorghum bicolor (L.) Moench. Six basic generations, namely P1, P2, F1, F2,BC1P1, BC1P2 of four crosses involving seven diverse parents were evaluated inrainy 2009. The mean performance of the F1 in all the crosses indicated dominantgene effect fo...

A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...

C ONNECTED VEHICLES is an emerging technical field which crosses multiple disciplines and industries including automotive, travel and transportation, information technology, communications, consumer electronics, industrial electronics, media and entertainment, energy and utilities. By connecting vehicles with various devices, services and participants, we are able to make our mobility more enjo...

Intense structuring of plant breeding populations challenges the design of the training set (TS) in genomic selection (GS). An important open question is how the TS should be constructed from multiple related or unrelated small biparental families to predict progeny from individual crosses. Here, we used a set of five interconnected maize (Zea mays L.) populations of doubled-haploid (DH) lines ...

The P family of transposable elements in Drosophila melanogaster transpose with exceptionally high frequency when males from P strains carrying multiple copies of these elements are crossed to females from M strains that lack P elements, but with substantially lower frequency in the reciprocal cross. Transposition is associated with enhanced mutation rates, caused by insertion and deletion of P...

In 2001, Sen and Churchill reported a general Bayesian framework for quantitative trait loci (QTL) mapping in inbred line crosses. The framework is a powerful one, as many QTL mapping methods can be represented as special cases and many important considerations are accommodated. These considerations include accounting for covariates, nonstandard crosses, missing genotypes, genotyping errors, mu...

Growth, puberty and pregnancy were studied in 665 crossbred heifers produced by breeding Hereford and Angus cows to Hereford, Angus, Red Poll, Brown Swiss, Gelbvieh, Maine Anjou, and Chianina sires. Estrus was determined from an average of 240 to 476 days of age. Puberty age was defined as age at first observed, standing estrus followed by an estrus within 45 days, except during the last 45 day...
