The correlations among seed yield components, and their direct and indirect effects on the seed yield (Z) of Russina wildrye (Psathyrostachys juncea Nevski) were investigated. The seed yield components: fertile tillers m(-2) (Y(1)), spikelets per fertile tillers (Y(2)), florets per spikelet(-) (Y(3)), seed numbers per spikelet (Y(4)) and seed weight (Y(5)) were counted and the Z were determined...

in order to select the suitable lines of red bean for chahharmahal & bakhtiari province, this experiment was conducted in lordegan & boldaji regions at 2001-2005. at the first year, single plants of local red bean (from lordegan, ardal, boldaji, dastgerd emamzadeh and gandoman regions) were selected at research farm for phenotypic characters, yield and yield components. at the second year, sele...

Sixteen Jatropha curcas genotypes collected from four states were grown in randomized block design and evaluated for 12 characters. The genotypes showed significant differences in most component traits and seed yield, excepting primary branches/plant, fruits/bunch and seeds/fruit. The genotypes Utkal nursery, Phule1, IST 1, Jodhpur1 and Chhatrapati had above average (>84.7 g) seed yield/plant. ...

Broad bean (Vicia faba L.) is an important crop worldwide. An increase in seed yield would increase both the grain reserve and the profit for farmers. Previous studies on increasing broad bean seed yield have focused mainly on increases at the whole population level. Few studies have focused on the differences in plant type within populations. In this study, we classified broad bean plants into...

Common bean (Phaseolus vulgar is L.) demand is increasing with an alarming rate around the world, especially in Latin America, Africa, and Asia. Therefore, increased bean yield per hectare i.s the best way to meet the world demand rather than expansion of area under cultivation. The objectives of this experiment were to determine the genotypic variations for green bean and dry seed yield and ma...

The effect of applying plant growth regulators on seed yield and quality of guinea grass (Panicum maximum) cv. Tanzania was studied in one crop on a sandy clay in Mexico. The treatments consisted of 3 growth regulators [ethephon, salicylic acid and a steroidal phytohormone (cidef-4)], 2 stages of application (before seed head emergence and at the beginning of anthesis) and 4 application concent...
