Diallel Analysis of Haploid Production Ability in Japanese Wheat Varieties Crossed with Hordeum bulbosum L.

A diallel analysis of height in wheat

مطالعه سیتولوژیک Hordeum bulbosum L. در ایران

گونه‌ Hordeum bulbosum همواره به عنوان یکی از منابع آللی مفید که می‌تواند در اصلاح غلات زراعی استفاده شود مد نظر است. در این تحقیق، کاریوتیپ 32 نمونه جمعیتی این گونه جمع‌آوری شده از نقاط مختلف ایران مورد بررسی قرار گرفت. تقارن کایوتیپی جمعیت‌ها و ارتباط آن با مناطق جغرافیایی ارزیابی شد. تمامی جمعیت‌های مطالعه شده تتراپلوئید با کاریوتیپ، متقارن بودند و شاخص‌های بررسی شده نشان از اتوتتراپلوئید بو...

Diallel analysis of some important Morpho-Phenological traits in bread Wheat (Triticum aestivum L.) crosses

Wheat (Triticum aestivum L.) is the most important food crop. It offers a great wealth of material for genetic studies due to its wide ecological distribution. The effects of GCA and SCA of morpho-phenological traits i.e. days to emergence, days to flowering, days to maturity, flag leaf length, grain filling duration, spike weight per plant, stem weight and grain yield were studied uti...

مقایسه روش‌های تلاقی گندم * ذرت و کشت بساک در تولید گیاهان هاپلویید گندم

The significance of haploid plants as genetic and plant breeding tools has been recognized for a long time. Haploid production techniques including anther culture, isolated microspore culture and intergeneric hybridization between wheat × Hordeum bulbosum and wheat × maize have been used to produce homozygous lines which accelerate breeding programs. In this study, wheat × maize hybridization a...

Different Salts Effects on the Germination of Hordeum vulgare and Hordeum bulbosum

The germination responses of Hordeum ulgare seeds to saline stress caused by different salt types was studied. For this, 25 seeds of mentioned species were placed on filter paper in Petri dishes containing distilled water (control), 60, 120, 180, 240, 300, 360 and 420 mM. saline solution of NaCl, CaCl2 an KCl. The results indicated that saline levels effects were significant (P < 0.05) for seed...
