Grain yield is the most important quantitative character in breeding of soybean (Glycine max (L.) Merrill), depending on both the genotypic potential and environmental conditions of soybean growing. Essentially, all of the genetic gains in soybean yield have been achieved by traditional breeding methods, involving hybridisation and phenotypic selection (CORYELL et al., 1999). Grain yield is a c...

Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...

Increasing the yield of oilseed crops is an important objective for biotechnologists. A number of individual genes involved in triacylglycerol metabolism have previously been reported to enhance the oil content of seeds when their expression is altered. However, it has yet to be established whether specific combinations of these genes can be used to achieve an additive effect and whether this l...

To evaluate the effect of residue of sulfonylurea herbicides and  wheat residues on the growth and yield of sunflower, a split factorial experiment was conducted based on a randomized complete block design (RCBD) with four replications at the College of Agriculture, Shiraz University, Shiraz, Iran. The treatments included with and without wheat residues from the tested farm as the main plots, a...

Five biotic and abiotic inducers namely, (Bio-Arc and Bio-Zaid) and (salicylic acid, K HPO and neem 2 4 oil) were examined for their effectiveness in controlling fungal diseases, improving growth and yield of alfalfa. The field trials have shown that salicylic acid, K HPO and neem oil respectively gave a significant P 0.05 2 4 protection against rust, downy mildew in both tested cvs. Ismailia-1...

in order to study the effects of drought stress on yield and yield components of safflower genotypes, a split plot based on randomized complete block design with four replications was performed at the research field, islamic azad university, arak, iran during summer of 2009. irrigation treatments included three levels of 100, 75 and 50% crop water requirement and four levels of safflower genoty...
