This experiment was conducted at two ecologically different regions, Boka,
and Gellien, using 3 lines of X.triticosecale Wittmack (372, C.187, and C.G.2)
and 6 cultivars of wheat (5 of them were triticum durum Cham1, Cham3,
Cham5, Bohoth5, and Hau
rani, and one of triticum aestivum Cham6), to assess
the changes in water content and dry matter in the grains during the period
from anthesis to physiological maturity .The results showed that all genotypes
had the same moisture content curves, whereas it had seemed that the two
durum wheat cultivars (Cham1 and Bohoth5) exhibited a disturbance in the
moisture development curves in the first region, and the same observation was
noticed on (Cham1, Cham3, and Cham5) in the second region. However,
triticale lines had a higher test weight of 1000 grain compared with wheat
cultivars in the two regions, and there was a positive relationship between grain
fill duration and the weight of 1000 grain, whereas, there was a depression in
the test weight of wheat cultivars in the second region in comparison with the
first one, but it is associated with an increase of protein percentage, and this
might be attributed to temperature elevation during grain fill stage.
