Advancements and strategies of genetic improvement in cassava (Manihot esculenta Crantz): from conventional to genomic approaches por Xiao, L., Cheng, D., Ou, W., Chen, X., Rabbi, I.Y., Wang, W., Li, K., Yan, H.

“…Finally, we put forward the perspective of developing genomic selection breeding model and super-hybrids of cassava through building inbreeding population and emphasize the generation of triploid cassavas, as well as using gene editing technology allowing cassava to be a tropical model plant to serve for basic biological research and molecular breeding.…”

Heritability of litter size in the Swedish population of Shetland sheepdogs por Eleryd, Annika

“…The results indicate that a breeding progress to increase litter sizes in the Swedish Shetland sheepdog population is possible with the implementation of best linear unbiased prediction (BLUP) based breeding values, if the trait is prioritised when selecting breeding animals.…”

Candidate gene sequencing and validation of SNP markers linked to carotenoid content in cassava (Manihot esculenta Crantz) por Udoh, L.I., Gedil, Melaku A, Parkes, Elizabeth Y., Kulakow, Peter A., Adesoye, A.I., Nwuba, C., Rabbi, Ismail Y.

“…Significant SNPs were used to design competitive allele-specific PCR assays and validated on the larger population for potential use in markerassisted selection breeding. Candidate gene sequencing of the genes β-carotene hydroxylase (crtRB), phytoene synthase (PSY2), lycopene epsilon cyclase (lcyE), and lycopene beta cyclase (lcyB) yielded a total of 37 SNPs. …”
