Grain filling duration

Ebook "Seed biology and yield of grain crops (2nd edition)" of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population.

The present investigation was carried out to estimate relative heterosis and heterobeltiosis in wheat genotypes to identify desirable cross combinations under high temperature stress for days to heading, grain filling duration, days to maturity, plant height, number of tillers per plant, flag leaf area, number of grains per spike, peduncle length, spike length, 1000-grain weight, biological yield per plant, grain yield per plant and harvest index. The F1 crosses were made in half diallel fashion using 10 genotypes.

Wheat is a cool seasoned crop requiring low temperature during grain filling duration and therefore increased temperature causes significant yield reduction.

Photosynthesis is mainly depends on photosynthetic activity and green leaf area duration during grain filling stage, but this trait is highly influenced by environmental factors such as temperature, soil type and amount of rainfall.

Results suggested that due to its maximum heritability, early selection would be feasible in cross Hashim-08 × LU-26, while due to low heritability and variation in cross Parula × Blue Silver, delayed selection will be effective. Yield improvement based on duration of grain filling could be done through selection in later generations until the accumulation of the maximum favorable additive genes is achieved.
