The experiment was conducted using Randomized Complete Block Design with Row Column arrangement and three replications. Grain yield, phenological and other traits were recorded. The Residual Maximum Likelihood (REML) combined analysis of variance across locations showed very highly significant (P

This study aims to develop content-based image retrieval (CBIR) system for the retrieval of T1-weighted contrast-enhanced MR (CE-MR) images of brain tumors. When a tumor region is fed to the CBIR system as a query, the system attempts to retrieve tumors of the same pathological category. The bag-of-visual-words (BoVW) model with partition learning is incorporated into the system to extract info...

مقدمه: برآورد دقیق اجزای واریانس ژنتیکی و غیر ژنتیکی با اطلاعات شجره‌ای و ژنومی، از ملزومات پیش‌بینی صحیح ارزش‌های اصلاحی می‌باشد. دسترسی به آرایه‌های چندشکلی تک‌نوکلئوتیدی (SNP) با تراکم بالا و افزایش تعداد حیوانات با اطلاعات ژنوتیپی، دقت و صحت برآوردهای مبتنی بر جمعیت را افزایش می‌دهد. انتخاب ژنومی به‌طور بالقوه‌ای قادر است بیشتر واریانس ژنتیکی را توسط نشانگرها توجیه نماید. هدف از مطالعه حاضر...

Data on 368 birth records of Swedish Red and White cattle herd raised organically at Dogan Organic Dairy Cattle Farm for a period of 2006 and 2009 (4 years) were used to estimate the effects of different environmental factors on birth weight. Additionally, a comparison of four methods for variance component estimation to compute heritability of birth weight was performed using ML (Maximum likel...

The main aim of sire evaluation is to obtain an accurate, efficient and ranking them according to their merit so as to enable the breeder to choose the best bulls. Today, the need for sire evaluation for their additive genetic ability (breeding values) or transmitting ability to its progeny has been recognized. For assessing the breeding values of bulls for the traits viz. age at first calving ...

Genetic parameters and breeding values were estimated based on 11 708 daily milk yields from 2255 lactations (1351 sheep, 19 different flocks) between the years 2004 and 2010. The pedigree covered 2334 individuals, including both the recorded animals and their known ancestors. The fixed effects were estimated by the least-squares method, while the genetic parameters were estimated by the REML m...
