Evaluation of yield and its components of some Egyptian wheat cultivars

الملخص EN

The field experiment was conducted to evaluate the yield and yield components of four Egyptian wheat cultivars, namely Gemmeiza11, Giza 168, Sids 12, and Bani Sweif 5.

The field experiment was laid out in RCBD design with three replications during the two growing seasons (2019/2020 and 2020/2021) at Abu El Matamir region, Beheira Governorate, Egypt.

The current study screened the four Egyptian wheat cultivars for 11 traits, including the number of days to anthesis, number of days to physiological maturity, grain fill duration, plant height, number of spikes, number of grains per spike, grain weight, grain yield, straw yield, biological yield, and harvest index.

For the number of days to anthesis, the highest genotype was Giza 168 in both seasons, while the lowest genotype was Sids 12 in 2019/2020 season and Bani Sweif 5 in 2020/2021 season.

As regard days to maturity, the earliest genotype was Sids 12, whereas Gemmeiza 11 was the latest genotype in both seasons.

The results also showed that Gemmeiza 11 had the highest value of grain fill duration in both seasons, while Giza 168 and Sids 12 had the lowest value in 2019/2020 and 2020/2021 seasons, respectively.

For plant height, Gemmeiza 11 was the tallest genotype in both seasons, while the shortest genotype was Bani Sweif 5.

Concerning the number of spikes /m², the highest genotype was Bani Sweif 5 in both seasons.

Concerning the number of grains/spike, the highest genotype was Sids 12 in both seasons.

For grain weight and harvest index, the highest genotype was Gemmeiza 11, in both seasons.

Concerning grain yield, straw yield, and biological yield, the highest genotype was Gemmeiza11 in 2019/2020 season and Bani Sweif 5 in 2020/2021 season.
