Ontogenetic analysis of yield components and yield stability of durum wheat in water-limited environments

Abstract: One main reason for the slow improvement of durum wheat in water-limited environments is the lack of clear understanding of the interrelationships among yield components and their compensatory changes under low and erratic moisture availability. Five cultivars, varying in many physiological attributes, were tested under different drought-stress conditions in field and greenhouse experiments . The cause-effect relationships of duration of vegetative period, duration of grain-filling period, number of spikes per… Show more

“…For commercial production and human consumption, durum wheat is the second most important Triticum species, next to common wheat (Triticum aestivum L.). Grain yield in smallcereals can be analyzed in terms of three primary yield components (number of spikes m−2, number of grains spike−1 and mean grain weight) that appear sequentially with later-developing components under the control of earlierdeveloping ones (Garcia del Moral et al, 1991;Simane et al, 1993). In the Mediterranean region, the magnitude attained by these grain yield components could be limited by low and unpredictable seasonal rainfall as well as higher temperatures towards the end of the crop cycle.…”

“…These was a strong compensation between panicles per m 2 and spikelets per panicle. In cereal crops, the compensation among yield components always arises (Nickell and Grafius, 1969;Heinrich et al, 1983;Simane et al, 1993;Zeng and Shannon, 2000), either from the physiological competition or from the developmental allometry (Grafius et al, 1976;Grafius, 1978), and it has been held to largely contribute to the failure in breeding efforts to improve yield potential through indirect selection for yield components in cereals (Li et al, 1998). In the present study, the compensation between panicles per m 2 and spikelets per panicle was not significant for spikelets per m 2 between CTTP and NTDS.…”

“…The lower value of WUE of 1-yr in wheat meadow and wheat mixture SY than 2-yr and 3-yr rotations in wheat meadow under both irrigated treatment evidenced that the benefit of forage crop rotations expire its effect since the 2-yr wheat rotation (Figures 1(a), 4(b) and Table 3) [7,21]. According to Rinaldi and Ubaldo [12] and Cui et al [1], the higher values of WUE of the wheat meadow and wheat mixture rotations under irrigated than rainfed treatment, was a consequence of the delay of vegetative cycle (on average 12 days, data not shown) of wheat favoured by water supply which exposed the organs of plant to a longer period of transpiration with a consequent use of water for respiration rather than WUE of physiological process [5,19,20].…”

“…The variation existing between SY and SY component traits in rainfed and irrigated treatment in continuous wheat, wheat meadow and wheat mixture rotations was a consequence of reduced effect of environmental stress on plant development in Mediterranean-type climate [19,20]. According to García del Moral and Rharrabti [5] and Martiniello [4], the reduced variation (difference between 1-yr and 3-yr rotations) between SY in wheat meadow and wheat mixture rotations under irrigated (1.12 and 0.93 t·ha…”
