Segregation pattern and inbreeding depression in F2 generation of some hybrid okra varieties

Estimates of inbreeding depression and heritability for yield and yield components from the F2 generation of a common bean diallel cross

Evidence for Heterosis in Italian Ryegrass (Lolium multiflorum Lam.) Based on Inbreeding Depression in F2 Generation Offspring from Biparental Crosses

Italian ryegrass is one of the most important temperate forage grasses on a global basis. Improvement of both dry matter yield and quality of herbage have been major objectives of pasture grass breeding over the last century. F1 and F2 progeny sets derived from controlled pair-crosses between selected Italian ryegrass genotypes have been evaluated for yield and nutritive quality under field con...

Inbreeding and Inbreeding Depression on Body Weight in Iranian Shal Sheep

The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...

A next generation of studies: Heterosis and inbreeding depression

Heterosis or hybrid vigor is a phenomenon in which the F1 progeny is superior in characteristics than its inbred parents. Inbreeding depression refers to the reduced vigor in the offspring from matings involving related parents. The world’s most important grain crop, Zea mays exhibits significant heterosis and inbreeding depression, and despite billions of dollars of sales and investments in hy...

coordination of protective schemes in distribution and subtransmission systems including distributed generation

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
