The effect of aqueous smoke extract, derived from Tanacetum parthenium, onin vitro plantlet regeneration from rapeseed (Brassica napus L. cv. Topas)microspore-derived embryos (MDEs) was evaluated in this study. Inoculation ofrapeseed MDEs with the smoke-extract dilutions (1:250, 1:500, 1:1000 and 1:2000)for various times (5, 10 and 15 min) significantly enhanced the percentage ofregenerated pla...

Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 12 alfalfa half-sib families. Thirty five individuals of each half-sib family were grown and analyzed basis of completely randomized ...

The present study was aimed to compare the photoautotrophic (PAM) and photomixotrophic micropropagation (PMM) of three potato cultivars (Hermes, Rosetta and Asterix). Cultures were initiated from single node explants and established in MS basal medium with some modifications. Potato plantlets responded in sugar-free media although sugar-containing media (PMM1 and PMM2) performed better as compa...
