“…Consequently, lines sown in spring having shorter stems were observed to be more resistant to lodging, whereas those sown in autumn showed moderate lodging near harvesting time. Similar findings for plant heights above 100 cm and severe lodging for einkorn lines were reported in the literatures [33,34,35]. By evaluating morpho-agronomic variability of 1039 einkorn accessions obtained from several world gene banks, it was reported that wild form (T. monococcum subs.…”

“…In this manner, einkorn lines sown in autumn, which exhibited average 93 days more heading time and taller plants, provided higher gross grain yields by producing longer spikes with more spikelets including heavier grains but less glume and protein content than those sown in spring. Similarly, it was reported that the relationship between thousand grain weight, number of spikelets per spike, grain weight per spike and grain yield per plant were to be found significant for 22 einkorn lines [35].…”

“…and more NSS (31-42, Avg. 36) were recorded for 22 einkorn wheat accessions evaluated in the Institute of Plant Genetic Resources "Konstantin Malkov"-Sadovo, Bulgaria [35]. Because NSS is quite variable yield related component among the einkorn genotypes, different values were reported in the literatures [33,36].…”

Nowadays diploid einkorn wheat (Triticum monococcum L. ssp. monococcum), widely cultivated in the Neolithic age, has been reconsidered as the valuable genetic resource for breeding and organic farming due to its high resistance to pests and diseases, adaptation to harsh climates, ability to provide acceptable yields on poor soils even with low/without inputs and high nutritional values. In this research, local 45 cultivated einkorn lines, selected from 500 single rows planted by each single spikes collected from total 50 farmers’ fields in 34 villages of Kastamonu/Turkey, were evaluated in terms of their morpho-agronomical traits and nutritional characteristics during two sowing seasons, autumn 2017 and spring 2018. Einkorn lines sown in two different seasons showed significant variations for heading time, plant height, lodging susceptibility, spike length, number of spikelets per spike, gross grain yield, amount of glume, single kernel weight, kernel diameter, hardness index, grain protein content and the color (a, b, L) values of flour. Furthermore, most of the correlation coefficients between these characteristics were found to be significant. All lines showed “facultative” growth habit, flowering well when sown both in autumn and in spring. Although lines sown in autumn had more yields, the same lines sown in spring provided higher grain quality and more resistance to lodging due to having shorter stems. In order to enable sustainable future use of einkorn, further research is suggested for reduction of plant height to avoid lodging and improvement of grain yield to compete with modern high yielding wheat cultivars.

“…It was observed that grain yield/plant and 1000-kernel weight had significant SCA effects (Hassan et al, 2007). Correlation studies (Desheva and Kyosev, 2017) suggested that spike length, 1000-kernel weight, grain weight/spike and grains per spike showed valuable contribution in grain yield, while, grain yield also affected by plants/m 2 and spikes/m 2 significantly (Asrar et al, 2016). The role of peduncle length in yield improvement is not fully understood.…”

The main emphasis of wheat breeders is to strive for genetically more stable, high yielding varieties than the pre-released ones to sustain the yield. Yield improvement efforts should be made while considering all contributing factors that can improve it. The role of peduncle length influencing yield and other supporting features are barely taken into consideration, and still not fully elucidated. Understanding and utilization of plant natural response will help to develop genetically and morphologically more adaptable genotypes for ever-increasing feed demand. The present research was conducted to assess the nature of gene action controlling inheritance of these traits coupled with manipulating role for yield traits. In this regard, 27 F1 hybrids were developed by crossing 9 female and 3 male parents using Line × Tester (L×T) mating design and evaluated for yield and its related traits. The analysis of variance for combining ability pointed out the presence of broad genetic variation in material with highly heritable nature. Correlation studies portrayed strong phenotypic and genotypic association between peduncle length, plant height, flag leaf area, spike length and grain weight/plant. Strong association of peduncle length with other yield contributing traits may be utilized as an indirect selection criterion for yield improvement. Hence, short stature and high yielding varieties can be developed by controlling the favourable genes for peduncle length. All yield related traits except peduncle length, spike length, and flag leaf area were controlled by dominant genes. Selection in the later generations for peduncle length may indirectly improve yield.

“…These results were in agreement with those obtained by (Iqbal et al, 2017), They also found high positive phenotypic correlation for grains/spike with grain weight/spike and spike length with grains/spike. In a correlation study, Desheva and Kyosev (2017) found that 1000-kernel weight, spike length, grain weight/spike and number of grains/spike showed significant and valuable contribution in grain yield. Also, (Gerema et al, 2020) observed positive highly significant correlation for plant height with spike length and tillers with grain yield per hectare.…”

Eight bread wheat (Triticum aestivum L.) genotypes included 6 lines and 2 testers were crossed in a line × tester mating design. The 12 F1's and their parents were evaluated for grain yield/plant and 9 agronomical traits. The results indicated highly significant genetic variability for all studied traits. Line Q8 was the best combiner for early flowering date, grains/spike, grain weight/spike and 1000kernel weight traits. While line Q10 was the best parent for tallness and grain yield/plant. The T1 (PI330456) was a potential tester parent for spike length, spikelets/spike, stem diameter, grains/spike, and grain yield/plant. While T2 (PI330458) was good combiner for earliness and 1000-kernel weight. Several hybrids showed highly significant positive specific combining ability (SCA) for some studied traits. Mother lines played a positive influential role towards plant height, spike length, tillers/plant and grain weight/spike. While paternal testers influence was predominant for days to flowering, spikelets/spike, stem diameter, grains/spike, 1000-kernel weight and grain yield/plant. Additive gene action was found for plant height, spikelets/spike, stem diameter grains/spike and grain weight/spike. While, for days to flowering, spike length, tillers/plant, 1000-kernel weight and grain yield/plant, non-additive gene action was predominant. High estimates of broad-and narrow-sense heritability for grains/spike, grain weight/spike, plant height and 1000-grain weight. Maximum genetic advance along with high narrow-sense heritability were observed for grains/spike and plant height reflecting that a reliable selection for these traits can be made on the basis of phenotypic performance in early generations. Highly significant positive correlations were observed between most studied traits.
