Plant phenology and grain development traits including (days to anthesis, days to maturity, plant height and grain filling duration) and grain yield and its components traits (spikes number /m<sup>2</sup>, grains number /spikes, grain weight, grain yield, straw yield, biological yield and harvest index) were studied. The analysis of variance indicated that there were highly significant differences between cultivars for most of these traits in both seasons under both normal and heat-stressed conditions. Related to plant phenology and grain development traits, the highest cultivar under heat-stressed conditions at most of these traits was Giza 168 whereas Bani Sweif 5 was the lowest. Concerninggrain yield and its components traits, the highest cultivar under heat-stressed conditions for spikes number /m<sup>2</sup>, grain yield, straw yield and biological yield was Bani Sweif 5. Giza 168 was the lowest for grain weight, grain yield, straw yield and biological yield. These results revealed that Bani Sweif 5 cultivar can be used for heat stress programs in wheat.https://jpp.journals.ekb.eg/article_265992_c2d6df53389fdad41a433f70979e6b14.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669131020221001Half Diallel Analysis and Heat Stress Tolerance Indices for Grain Yield in Bread Wheat76377326525210.21608/jpp.2022.161348.1168ENH.

Mean squares due to genotypes, parents, crosses, general (GCA) and specific combining ability (SCA) were significant or highly significant for the most traits. Days to heading (DH), plant height (PH), spike length (SL) under both dates in addition spikes/plant (NS/P), biological yield/plant (BY/P), harvest index (HI) and 1000 grains weight under normal date and grain yield/plant (GY/P), grains/spike (NG/S) under late date were controlled by additive gene action. The rest traits were controlled by dominance gene action. Under normal date, Sids 14 proved to be a good combiner for NS/P and BY/P. All crosses showed positive highly significant heterobeltiosis for GY/P. The crosses P1XP5 and P3XP4 showed significant or highly significant positive SCA for BY/P, GY/P, number and weight of grains/spike. Under late date, Gemmeiza 11 and Misr 2 proved as good combiner for BY/P, GY/P and NG/S. Significant positive GCA effects found for GY/P of Shandaweel 1. SCA effects were positive significant or highly significant for BY/P and GY/P of the four crosses P1XP3, P1XP5, P2XP6 and P4XP6. The crosses P2XP6, P3XP4, P3XP6 and P4XP6 showed highly significant heterobeltiosis for GY/P. It could be concluded that the two crosses of P1XP5 and P2XP6 were the most heat tolerance with high yield and could be used to obtain segregating populations to apply selection.https://jpp.journals.ekb.eg/article_265252_21eb43d0ed057bdd5f6271658a55c67b.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669131020221001Effect of Planting Methods on the Productivity of some Egyptian Rice (Oryza sativa L.) cultivars77578126567010.21608/jpp.2022.152877.1148ENA.

Days to heading, plant height, number of productive tillers m<sup>-2</sup>, panicle length, panicle weight, number of filled grains panicle<sup>-1</sup>, number of unfilled grains panicle<sup>-1 </sup>and 1000-grain weight, grain yield, biomass yield, harvest index and production efficiency were measured. There were no significant differences between regular and parachute transplanting methods on plant height, number of productive tillers\ m<sup>2</sup> and panicle length whereas the drill planting method recorded the lowest values in both seasons except days to heading showed no significant difference with parachute transplanting. The interaction between planting methods and rice cultivars had a significant effect on the number of days to heading, number of productive tillers m<sup>-2</sup> and plant height. There were no significant differences between parachuting and regular transplanting methods in panicle weight, number of filled grains panicle<sup>-1</sup> and 1000-grain weight where the parachute transplanting method recorded the highest values followed by regular transplanting in the first season. On contrary, the highest values were given by regular transplanting followed by parachuting in the second season. Also, there were no significant differences between regular and parachute transplanting in 1000-grain weight, grain yield, biomass yield and harvest index. These results revealed that regular and parachute transplanting methods are efficient and farmers can choose between them based on their capabilities.https://jpp.journals.ekb.eg/article_265670_0183e6ef1e6b18a889c176c89a14a6b2.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669131020221001Influence of some Storage Conditions on Grain Quality Characters of some Egyptian Rice Cultivars78378926621610.21608/jpp.2022.160818.1167ENKh.

Newly harvested certified seeds in 2018 and 2019 seasons of three rice cultivars namely, Sakha 101 as japonica cultivars, Giza 178 as indica/ japonica cultivars, and Egyptian Yasmin as indica cultivars were provided by Rice Research Program, Agriculture Research Center, Sakha, Kafr El-Sheikh, Egypt. A split- split plot design with three replicates was used. The most noteworthy qualities for hulling % and milling % by keeping Sakha 101 for 3 months in jute bags in both seasons. Furthermore, data revealed that keeping Egyptian Yasmin for year in polyethylene bags showed predominance values for broken %, amylose content % and protein content % in both study seasons. Most elevated values for elongation % and water uptake were realized by keeping Egyptian Yasmin for year in jute bags in both seasons. Most elevated values for gel consistency were recorded by keeping Sakha 101 for year in jute bags while; the most noteworthy values for spreading and clearing were realized by keeping Sakha 101 for 3 months in polyethylene bags in both seasons. We recommend to store paddy rice in jute bags for getting best quality characteristics for rice.https://jpp.journals.ekb.eg/article_266216_bb2e969f826294369746d067eea2dfef.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669131020221001Potassium Fertilization and Micronutrients Foliar Spray Effects on Peanut Productivity and Its Export Traits Using Giza 6 and Nc 9 Peanut Varieties, in Sandy Soils79179826753810.21608/jpp.2022.161489.1169ENManal Sh.Abd El-HaliemAgronomy Department, Faculty of Agriculture, Suez Canal university, Ismailia, Egypt.H.

NC 9 variety significantly surpassed Giza-6 variety in all studied characters (plant height, number of branches/plant, fresh straw weight/plant (g) dry straw weight/plant (g) number of pods/plant, weight of pods/plant (g), weight of seeds /plant (g), weight of 100 pods (g), weight of 100 seeds (g), seeds weight per 100 pods (g) and shelling percentage = (seed yield/pod yield) × 100). Plant height, weight of 100 pods, weight of 100 seeds, seeds weight per 100 pods, seed oil percentage and pod, seed, oil, fodder and biological yields/fad were significantly increased by raising potassium fertilization rate up to 75 kg K<sub>2</sub>O/fad either under spraying plants with micronutrients or without it.For all aforementioned characters, a significant interaction between potassium fertilization, micronutrients spray and peanut varieties was recorded. The highest values of the previous traits were produced from NC9 variety fertilized with 75 Kg K<sub>2</sub>O /fad and sprayed with micronutrients. While the lowest values were achieved from Giza 6 variety unfertilized with potassium and unsprayed by micronutrients. The study recommends planting NC9 cultivar, fertilizing at a rate of 57 kg K<sub>2</sub>O/feddan, and foliar spraying with microelements under the conditions of Nafesha area, Ismailia governorate.https://jpp.journals.ekb.eg/article_267538_dbf6173bac4b3ebdb5b1e73da1aa093c.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669131020221001Improvement Grain Yield and Yellow Rust Resistance in Four Bread Wheat Crosses79980626752710.21608/jpp.2022.169213.1177ENM.

The experiments were conducted during four successive growing seasons from 2018/19 to 2021/22</strong><strong>. </strong>For most studied characters in the F<sub>2</sub> and F<sub>3</sub> generations, the genetic variances indicated an important role with moderate to high broad sense heritability. Variations in all studied traits among F<sub>3</sub> families in the four crosses were significant. Regarding yellow rust, the parent Misr 3 was resistant while Sakha 93, Sakha 95 were moderately resistant, Line 1 was moderately susceptible and Misr 1 was susceptible. Yellow rust resistance in the two parents of cross 1 and cross 3 were controlled by one dominant gene for yellow rust. On the other hand, cross 2 and cross 4 were controlled by two dominant genes. The final selection based on grain yield and yellow rust resistant resulted in 11 families from Line 1 × Misr 1 cross, 12 families from Line 1 × Misr 3 cross, 4 families from Line 1 × Sakha 93 cross and 6 families from Line 1 × Sakha 95 cross. These 33 families seemed to be promising genotypes thus, they will be evaluating to select the best lines having highest agronomic traits and yellow rust resistance.https://jpp.journals.ekb.eg/article_267527_737d8caed2e9c3fa6445e952d915efea.pdf
