Genetical and environmental analyses of yield in six biparental soybean crosses

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...

Heritability and correlation of grain yield and its components in F2 plants of ten six-rowed barley crosses

Assessment of Genetic Variability, Correlation and Path Analyses for Yield and Its Components in Soybean

A study was conducted at the National Agriculture Research Center, Islamabad during summer 2001 on 27 genotypes of soybean to determine the correlation and path analyses of yield and its components. Significant differences among genotypes for characters viz., leaf area, chlorophyll content, first pod height, days to 50% flowering, days to flowering completion, days to pod initiation, days to 50...

Heterosis and Inbreeding Depression in Two Soybean Single Crosses

Heterosis is considered to be of little importance in soybean (Glycine max L. Merr.) because the crop is produced as “pure-line” cultivars or blends of inbred lines. The F1 generations Holladay/ Hutcheson (Cross 1) and Brim/Boggs (Cross 2) were generated by hand pollinations. Inbred generations were generated by bulk selfing. The F1, F2, F3, F4, and F5 generations were yield-tested in replicate...

Biplot Analysis of diallel crosses for yield and some morphological traits in durum wheat

Six varieties of durum wheat were included in a full diallel mating design during 2003-2004 and 2004-2005 cropping seasons in the farm of Maragheh Dryland Agricultural Research Institute (DARI), Iran. Parental durum wheat genotypes and their complete diallel progenies were grown in a randomized complete block design with two replications in the growing seasons of 2005-06. The highest values of ...
