GWAS: Fast-forwarding gene identification and characterization in temperate Cereals: Lessons from Barley – A reviewUnderstanding the genetic complexity of traits is an important objective of small grain temperate cereals yield and adaptation improvements. Bi-parental quantitative trait loci (QTL) linkage mapping is a powerful method to identify genetic regions that co-segregate in the trait of interest within the research population. However, recently, association or linkage disequilibrium (LD) mapping using a genome-wide association study (GWAS) became an approach for unraveling the molecular genetic basis underlying the natural phenotypic variation. Many causative allele(s)/loci have been identified using the power of this approach which had not been detected in QTL mapping populations.

Effect of various food on the growth of Gryllus bimaculatus De Geer, 1773 and proposal of a breeding processCurrently, cricket farming is becoming more and more popular since it brings high economic efficiency to farmers. Crickets can be raised in a small area, are easy to care for, have a short harvest time, and have no pollution problem. This paper provides insight into the effects of three types of food on the growth and development of crickets (Gryllus bimaculatus) and proposes the rearing process of crickets.

Combining ability and gene action studies in new intra Hirsutum hybrids with suggested breeding strategiesThe prime objective of any plant breeder is developing new cultivars with high yield. The present investigation aimed at estimating the general combining ability among parents and specific combining ability in hybrids for various yield and related traits in upland cotton. Forty hybrids were obtained by crossing 8 elite lines with 5 selected testers in a Line × Tester fashion.

Embryonic mortality in cattle - A reviewCattle is one of the major livestock species for milk production, contributing significantly to the economy of our country and continuous milk production needs regular conception and successful calf crop production. World-over, for dairy economy, there is emphasis on one calf per year per cattle. Successful calving follows survival of the conceptus through embryonic and fetal development. Embryonic mortality is a major source of economic loss with mortality rate upto 40% in animal production through repeat breeding and increased cost of artificial insemination, cost of treatment, extended calving intervals and prolonged dry period resulting in reduced milk production.
