Analysis of Re-Heterosis for Yield and Fruit Quality in Restructured Hybrids, Generated from Crossings among Tomato Recombinant Lines

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...

Heterosis Decreasing in Hybrids--Yield Test Inbreds

U.S. corn production was 53 million Mg annually and corn yield averaged 1518 kg ha in the 1930s, when corn hybrids were first commercially grown. Corn production grew to 76 million Mg annually in the 1950s, to 150 million Mg annually in the 1970s, and to 219 million Mg in the 1990s (USDA/NASS 2007). In 2001 corn became the highest tonnage cereal crop worldwide: 557.6 million Mg of corn, 542.4 m...

Implications of heterosis and combining ability among productive Single cross hybrids in tomato

Ten tomato commercial and productive single cross hybrids extensively grown in Northern Transitional Zone of Karnataka were planted in the field at UAS, Dharwad following RBD design with three replications. A 10 x 10 diallel set was generated by crossing these single cross hybrids in all possible combinations (excluding reciprocals) and 45 double cross hybrids were planted during February, 2007...
