Genotypic coefficient

Levels of inbreeding in cattle populations have increased in the past due to the use of a limited number of bulls for artificial insemination. High levels of inbreeding lead to reduced genetic diversity and inbreeding depression. Various estimators based on different sources, e.g., pedigree or genomic data, have been used to estimate inbreeding coefficients in cattle populations.

As a pestivirus of the Flaviviridae family, bovine viral diarrhea virus (BVDV), has imposed a large burden on animal husbandry worldwide, and such virus can be transmitted mainly through direct contact with other infected animals and probably via aerosols. In the present study, we aimed to develop a real-time RT-PCR method for detection of BVDV-1 in aerosol samples.

Wheat stripe rust (caused by Puccinia striiformis f. sp. Tritici), is a major disease that causes huge yield damage. New pathogen races appeared in the last few years and caused a broke down in the resistant genotypes. In Egypt, some of the resistant genotypes began to be susceptible to stripe rust in recent years.

Thirty six diverse genotypes of Indian mustard (Brassica juncea L. Czern and Coss.) were evaluated for ten quantitative. The variability indicates that Genotypic coefficient of variation (GCV) was moderate for 50% flowering, days to maturity, total no. of siliqua per plant, biological weight, test weight and seed yield; low for plant height, no. of siliqua on main shoot, no. of seed per siliqua and harvest index.

A field experiment was conducted to estimate the genetic variability, trait association and path coefficient analysis among the Indian mustard genotypes during rabi, 2019. Analysis of variance revealed the mean sum of squares due to genotypes was highly significant for all the characters studies indicating the existence of ample variability among the genotypes studied. The high GCV and PCV observed for number of siliquae per plant and secondary branches per plant indicated the influence of environment on the expression of these characters were at minimum level.
