Abstract
The present study was carried out to evaluate some Stevia rebaudiana segregates
to facilitate selection of superior genotypes for hybridization in breeding programs.
Three varieties, namely Sugar-High-A3, Egy.1 and Shou-2 and their F1 populations were
evaluated for their morphological characteristics at Giza Research Station (latitude of
30.02o N and longitude of 31.22o E) in 2017 and 2018. Various quantitative
morphological traits including plant height, number of branches/plant, number of
leaves/plant, leaf fresh and dry weight/plant, leaf moisture%, stems fresh weight and
leaf: stem ratio were recorded. Individuals were identified with leaf fresh weight ranging
from 40 to 670 g, while the highest leaf dry weight (215 g) was recorded by strain No. 2
of Egy.1 variety. Shou-2 variety had the highest leaf dry weight (60 g/plant). Stevia Egy.1
variety produced the highest percentage of superior strains (65 %), compared to the other
varieties. Correlation indicated that, leaf dray weight was positively and highly
significantly correlated with leaf fresh weight and leaf number/plant, recording 0.97 and
0.81, respectively.
