EVALUATION OF SOME HEAT TOLERANT WHEAT GERMPLASMS FOR YIELD AND YIELD QUALITY
AMAL HASSAN SELIM;
Abstract
Two and three field experiments were carried out in Agricultural Experimental farm, Kom-Ombo Experimental Research Station, Agric. Res. Center during 1997/98 and 1998/99 growing seasons, respectively.
Twelve semi dwarf wheat cultivars were. used in the present
investigation. Ten wheat cultivars (Triticum aestivum,L.) namely Qiza
160, Giza 164, Giza 165, Sakha 8, Sakha 69, Sakha 92, Gemmiza 3, Gemmiza 5, Sahel 1 and Sids 2 and two wheat cultivars (Triticum turgidum,L.) sub species durum namely Benisuef 1 and Sohag 3 were provided by wheat Research Section, Agric. Research Center, Ministry of Agriculture at Giza.
The results could be summarized as follows:
1. Genotypic effect:
1.1. GrQwth, yield attributes and yield:
The data revealed that Giza 165 gave the longest period from sowing to heading and to maturity in both growing seasons. The yield
attributes of plant Giza 164 including number of spikes/m2
main spike
characters (length, spiklets and grain number) were statistically the highest comparing to the other genotypes in both two growing seasons.
In the first season, plants of Gemmiza 5 had significant highest parameters of grain yield, biological yield, crop and harvest indices. it was in the second order after Giza 164 in its straw yield. Whereas, Giza 164
surpassed the other studies genotypes in the above yield parameters in the second growing season. The data of hard wheat genotypes showed higher response of Sohag 3 to grow and yield under high temperature stress than Benisuef I.
Therefore, it could be concluded that wheat genotype Gemmiza 5 was adapted to cultivate under high temperature stress in the first season. While, Giza 164 was more adapted to grow and yield under relatively less high temperature stress in the second season
