Genetic Relationship of Stalk Strength and Ear Height in Maize
creased by 22.5% over five cycles of selection for high RPR in MoSCSSS. The correlation between RPR and The rind penetrometer is an effective tool for measuring stalk EH is of interest in terms of direct vs. indirect selection strength in an effort to improve maize (Zea mays L.) germplasm for stalk lodging resistance. However, previous studies have indicated a for stalk strength. That is, to wh...
متن کاملPositive genetic correlation between brain size and sexual traits in male guppies artificially selected for brain size
Brain size is an energetically costly trait to develop and maintain. Investments into other costly aspects of an organism's biology may therefore place important constraints on brain size evolution. Sexual traits are often costly and could therefore be traded off against neural investment. However, brain size may itself be under sexual selection through mate choice on cognitive ability. Here, w...
متن کاملEstimating the genetic parameters for liver fat traits in broiler lines divergently selected for abdominal fat.
Intensive selection of broilers for improved growth rate is known to exert a negative effect on broiler health, such as an increase in body fat (and its related diseases). Excessive fat deposition in the liver can cause fatty liver hemorrhagic syndrome (FLHS); in addition, traits associated with liver fat have also been associated with FLHS. This study explored the genetic relationships among l...
متن کاملCorrelated genetic trends for production and welfare traits in a mouse population divergently selected for birth weight environmental variability.
The objective of this work was to study the changes that, selecting for environmental variability of birth weight (BW), could bring to other interesting traits in livestock such as: survivability at weaning (SW), litter size (LS) and weaning weight (WW), their variability assessed from standard deviations of LS, standard deviation of WW (SDWW) and also the total litter weight at birth (TLBW) an...
متن کاملComplex genetic architecture underlies maize tassel domestication
Maize (Zea mays) tassels underwent profound morphological changes during maize domestication and improvement. Although a number of genes affecting maize inflorescence development have been identified, the genetic basis of the morphological changes in maize tassels since domestication is not well understood. Here, using a large population of 866 maize-teosinte BC2 S3 recombinant inbred lines gen...
