selection of drought-tolerant half-sib families in sugar beet
one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...
متن کاملگزینش برای تحمل به خشکی در فامیل های نیمه خواهری (Half sib family) در چغندر قند
یکی از مؤثرترین روشهای کاهش مقابله با خشکی و افزایش رادمان مصرف آب، اصلاح و تهیه ارقام مقاوم به خشکی است که از تحمل بالایی به خشکی برخوردار بوده و به ازاء یک واحد کاهش مصرف آب، کاهش عملکرد کمتری داشته باشند. بدین منظور اصلاح گردهافشانهای دیپلوئید متحمل به خشکی بهعنوان یکی از پایههای رقم هیبرید مدنظر قرار گرفت. از چهار توده گردهافشان دیپلوئید، تعداد 45 فامیل نیمهخواهری تهیه و در شرایط تنش...
متن کاملCOMPARISON OF HALF-SIB AND FULL-SIB PROGENY SELECTION METHODS IN INDIAN MUSTARD (Brassica juncea L.) UNDER RAINFED CONDITIONS
An experiment was carried out to compare half-sib and full-sib progeny selection methods in Indian mustard (Brassica juncea L.) under rainfed conditions from 2006-07 to 2009-10 for 14 morpho-physiological characters. Full-sib and half-sib progenies were developed from different populations. The values of genetic parameters were higher in full-sibs compared to half-sibs for a greater number of t...
متن کاملStock Quality of Black Walnut (Juglans Nigra) Seedlings as Affected by Half-Sib Seed Source and Nursery Sowing Density
Morphological quality of black walnut (Juglans nigra L.) seedlings largely dictates their capacity to establish well in plantations and their performance potential for use as rootstocks in grafting. Larger seedlings and rootstocks, attained from propagation at relatively low nursery sowing densities, have comparatively more expansive root systems for exploitation of soil resources and greater n...
متن کاملOptimal haplotype reconstruction in half-sib families
In the goal of genetic improvement of livestock by marker assisted selection, we aim at reconstructing the haplotypes of sires from their offspring. We reformulated this problem into a binary weighted constraint satisfaction problem. Our results showed these problems have a small treewidth and can be solved optimally, improving haplotype reconstruction compared to previous approaches especially...
