HETEROSIS AND GENE ACTION STUDIES OF SOME YIELD AND YIELD COMPONENT TRAITS IN SQUASH

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

Path Analysis of Grain Yield and Yield Components and Some Agronomic Traits in Bread Wheat

JANMOHAMMADI MOHSEN, SABAGHNIA NASER, NOURAEIN MOJTABA. 2014. Path Analysis of Grain Yield and Yield Components and Some Agronomic Traits in Bread Wheat. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 62(5): 945–952. Development of new bread wheat cultivars needs effi cient tools to monitor trait association in a breeding program. This investigation was aimed to charact...

QTL mapping of forage yield and forage yield component traits in Sorghum bicolor x S. sudanense.

The sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense) is an important forage crop. However, little is known about the genetic mechanisms related to forage yield and the 4 forage yield component traits in this forage crop. In this study, a linkage map was constructed with 124 assigned SSR markers using an F2 mapping population derived from the crossing of sorghum Tx623A and sudangrass S...

Genetic Effects and Heterosis of Yield and Yield Component Traits Based on Gossypium Barbadense Chromosome Segment Substitution Lines in Two Gossypium Hirsutum Backgrounds

We hybridized 10 chromosome segment substitution lines (CSSLs) each from two CSSL populations and produced 50 F1 hybrids according to North Carolina Design II. We analyzed the genetic effects and heterosis of yield and yield components in the F1 hybrids and parents in four environments via the additive-dominance genetic model. Yield and yield components of the CSSLs were controlled by combined ...
