Research ArticleOpen accessIn the keywordsGenetic and Environmental Interactions in Spring Wheat Resistance to Bipolaris Sorokiniana Root Rot in KazakhstanYerlan Dutbayev, Ardak Bolatbekova, Aidana Kharipzhanova et al.Common root rot caused by Bipolaris sorokiniana represents a major constraint to wheat production in Kazakhstan. This study evaluated the resistance of 30 spring bread and durum wheat genotypes under diverse environmental and treatment conditions in two contrasting regions (Almaty and Aktobe) during 2024. The experimental design included three treatment regimes: fungicide application, artificial inoculation with the pathogen, and natural … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Mar 2026 · 1,517 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstimation of Adaptability and Stability of Nellore Sires, based on the Productive Progeny Performance Raised in Brazilian SavannaJúlio César De Souza, Fabio Fábio Rafael Leão Fialho, Carolina Fregonesi De Souza et al.The study investigates the performance and adaptability of Nellore sires across different regions, focusing on weight traits at 205 days (W205) and 550 days (W550). Analysis reveals significant variations in progeny weight means among evaluated sires, highlighting the importance of sire selection for herd improvement. Notably, certain sires consistently exhibit superior weight traits across diverse environmental conditions, indicating their potential … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 2 Jul 2024 · 5,529 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMultienvironment Analysis of Traits Relation and Hybrids Comparison of Maize Based on the Genotype by Trait BiplotSaeed Safari Dolatabad, Rajab Choukan, Eslam Majidi Hervan, Hamid DehghaniProblem Statement: The Genotype by Trait (GT) biplot can be used to compare cultivars on the basis of multiple traits and to identify cultivars that are particularly good in certain traits and therefore can be candidates for parents in plant breeding program. Approach: The objective of this study was to evaluate the maize hybrids based on Genotype by Traits (GT) … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,234 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Phenotypic Plasticity in Dairy Production Traits of Toggenburg Goat Genotypes Across South African Agro-ecological ZonesMatshebuka Tshepho, Obert Tada, Louis Thobela TyasiThe study evaluated phenotypic plasticity (PP) in reproductive and milk production traits of Toggenburg (TOG) goat genotypes across five South African agro-ecological zones (AEZ) using a longitudinal observational design. Data from 2,417 does representing five genotypes (Founders, CP, Appendix A, Appendix B, and StudBook Proper) were sourced from the Milch Breeders Society of South Africa LOGIX database. Descriptive statistics and … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 25 Nov 2025 · 2,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Body Weight and Age at Puberty and Mating on Subsequent Gilt Development Weights, Litter Traits, and Colostral Immunoglobulin G of the F1 Large White X Landrace GiltsThembela Happines Matukane, Khathutshelo Agree Nephawe, Bohani Mtileni et al.The purpose of this study was to assess how body weight and age at puberty and mating in F1 Large White x Landrace pigs influence subsequent gilt development weights, litter characteristics, and colostral immunoglobulin G levels. A total of 168 gilts were categorized into different weight groups, i.e., body weight at puberty (lighter gilts: <103 kg, moderate gilts: 103-109 kg) … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 12 Oct 2024 · 5,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractBeef Productivity of Limousine Cattle at Stable KeepingIrina Vlasova, Inna Ventsova, Alexander Vostroilov et al.The regularities of the post-embryonic development of farm animals have been studied by numerous researchers. Their ontogenesis is a result of the complex interaction of animal genotype with those conditions of the external environment in which their hereditary basis is realized. In Russia, the stable keeping system of the cattle is highly relevant as many farms do not have large … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 23 Oct 2020 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgress Made in Developing New High Yielding Potato Varieties for the Kenyan Highlands at KALRO-TigoniJane Muthoni, Hussein ShimelisBreeding has been going on at Kenya Agricultural and Livestock Research Institute (KALRO), Tigoni in Kenya to develop high yielding potato varieties that have good processing qualities. The objective was to develop high yielding potato varieties that are adapted to the Kenyan climatic and environmental conditions and that are suitable for processing. After initial crossing, the resultant families were evaluated … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 28 Jun 2018 · 8,915 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Association of Early Pregnancy Loss with Polymorphism in Xenobiotics Detoxification GenesElena Vladimirovna Mashkina, Konstantin Nikolaevich Saraev, Elena Viktorovna Butenko et al.Pregnancy loss and other pregnancy complication can be connected with environmental and lifestyle risk factor, among which effect of chemical compounds is the strongest. Effects of xenobiotics can be modified by allele variants of xenobiotic detoxification enzymes phase I or II. A total of 71 women with early pregnancy loss and 101 control patients were examined by a case-control methodology. … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 6 May 2015 · 7,032 accessesView PDFCite
