Heading date effect on winter Triticale (X Triticosecale Witttmack)‎ grain yield production

الملخص EN

A total of 10 Triticale genotypes were grown in a Randomized Complete Block Design using 3 replications to improve our understanding the importance of different heading date time (early and late) on triticale genotypes and its impact on grain yield.

Results of this study indicated that the early heading triticale genotypes are the best for grain yield production as example NT15406 genotype heading early (143 day) and produce the highest grain yield in Lincoln (6144.8 kg / h).

Significant differences were observed among genotypes regarding Heading date and grain yield.

Results indicated diverse effect of the different environments overall genotypes on the grain yield.

At Sidney, the overall mean of grain yield (4997.16 kg / h), and (4330.784 kg / h) for Lincoln.

Overall tow environments the highest grain yield genotypes were NT14407, NT15406 and NE03T416-1 with grain yield (5372.1, 5369.7 and 5267.1 kg / h, respectively).

Whereas, for grain yield, overall tow environments the highest significant grain yield genotypes were NE03T416-1 at Sidney and NT15406 at Lincoln with Grain yield (6024.1 and 6144.8 kg / h, respectively).

Current study showed high genetic variability among the studied triticale genotypes that could be used as a rich genetic resource for breeders to develop newer Jordanian Triticale drought tolerant genotypes.
