The current research aimed to evaluate and select bread wheat stable cultivars with high productivity across diverse sowing dates. Fourteen wheat cultivars were grown in a randomized complete block design with three replicates at six sowing dates during two successive seasons of 2018/2019 and 2019/2020 representing twelve environments. The cultivars were evaluated for grain yield and its attributes. Highly significant differences were obtained among the wheat cultivars, sowing dates, and their respective interaction for all measured traits. The highest grain yield (2.992-ton fed-1) was recorded on 30th November, after this date, each day delay in sowing of wheat onward decreases grain yield at the rate of 21 kg fed-1 day-1. Overall, the cultivar Gemiza 11 gave the highest grain yield with an average of 2.861 ton fed-1, recorded the highest 1000-GW with an average of 47.73 g, highest straw yield with an average of 8.303-ton Fed-1, and was the earliest cultivar with a mean heading date of 92.9 days. According to GGE biplot results, Gemiza 11, Gemiza 9, and Sakha 94 ranked in the first order as high-yielding cultivars and had greater stability level overall sowing dates under Assiut conditions. The most adequate cultivars for sowing in the first half of November (1st -15th ) are Misr 2, Sids 12, Sakha 95, Gemiza 9, and Gemiza 11. Also, Sakha 94, Gemiza 9, and Gemiza 11 can be sown after 30th November because they produce a satisfied yield, have good stability, and can be considered as late sowing tolerant.

Wheat (Triticum aestivum L.) is an important cereal crop all over the world as well as it is considered the major cultivated, most consuming staple food in Egy pt and for millions of people worldwide. Egypt remains a highly importer of wheat despite it was the first crop to be planted. To obtain high produc tion of wheat under Egyptian agriculture is one of the main targets of food production increa se in order to reduce the food gap as a result of the continuous population increase. Land reclamation is one of the important solutions for this reason which is the most important strategic aim to reduce the gap between production and consumption.

Effect of light-sources, quality, and intensities on morphogenesis, shoot multiplication, development and roots, and biomass production in Stevia investigated using shoot tips cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of plant growth regulators (PGRs). 2000 Lux intensity provided by fluorescent light lambs was found the most favorable for shoot induction and production, shoot length, number of leaves/explant and also for fresh and dry weights/foliage. Under this light condition, the optimum contents of photosynthetic pigments, cholorophyll a, cholorophyll b, total cholorophyll, and carotenoids recorded. Blue-LED light treatment created growth condition for the highest shoot elongation, leaves number/shoot, leaf fresh weight, leaf dry weight, and photosynthetic pigment production. Cent percent of shoot induction was obtained under red-LED treatment resulting in the largest number of shoot production. Root formation was promoted by 2000 and 3000 Lux intensities of light. However, the 2000 Lux intensity treatment provided the most favorable growth condition permitting generation of largest number of longest roots with maximum fresh/dry weights. Root induction was 100 percent under fluorescent light, the maximum fresh and dry weights of roots were achieved on blue-Led light and red-LED treatment induced the longest roots.

AN EFFICIENT and simple regeneration protocol using leaf explants was described on MS medium in the presence of various plant growth regulators. After four weeks of culture, the highest induction of adventitious shoot buds from leaf culture (90%) was achieved on MS medium with 1.0mg/L BA. The largest number of shoot buds (3.02) per leaf explant with no callus formation was achieved on MS medium with 2.0mg/L BA. The best combination for the induction of numerous shoot buds was found to be TDZ + BA + IBA (0.5, 1.0, and 0.5mg/L, respectively), which presented 10.4 shoots per explant with 3.15cm in length. For in vitro root formation stage, Healthy shoots were collected and cultivated on a half-strength MS with various concentrations of NAA and IAA alone or in combination with 2,4-D or IBA. Furthermore, the highest roots (8.17) per shoot with root formation (100 %) was observed using a half-strength MS medium in the presence of 2.0mg/L IAA. Therefore, healthy in vitro rooted plantlets were acclimatized successfully after four weeks in the greenhouse.
在多种植物生长调节剂的作用下，利用叶片外植体在MS培养基上进行高效、简便的再生。培养4周后，在添加1.0mg/L BA的MS培养基上，叶片不定芽的诱导率最高(90%)。在BA浓度为2.0mg/L的MS培养基上，叶片外植体的芽数最多，为3.02个，且无愈伤组织形成。TDZ + BA + IBA(分别为0.5、1.0和0.5mg/L)是诱导芽数最多的最佳组合，每个外植体可产生10.4个芽，芽长3.15cm。在离体根形成阶段，采集健康苗，在不同浓度NAA和IAA单独或联合2,4- d或IBA的半强MS培养基上培养。在2.0mg/L IAA浓度为半强度的MS培养基中，每枝生根数最高，为8.17根，生根率为100%。因此，健康的离体生根植株在温室中培养4周后就能成功地适应环境。

Lentil (Lens culinaris Medik.) is one of the winter season pulse crops which has a considerable nutritive value for human beings present in their seeds which contains about 21–31% protein, 43.4–69.9% total carbohydrate, 0.7–4.3% fat, 5.0–26% fiber and 2.2–4.2% ash (Joshi et al., 2017). Furthermore, like any leguminous crop, lentil cultivation can share in the sustainable development of agroecosystems. Its cultivation has a vital role in nitrogen cycling because it can be fix biologically about 85% of its required nitrogen from the surrounding atmosphere 14.39% of nitrogen is drawn from soil source (Gan et al., 2016; Kabir et al., 2019). In Egypt, statistics showed that lentils’ production in 2017 was only 480 tonnes which was produced from 235 ha (≈ 580.7fed) harvested area (FAOSTAT, 2019).
扁豆(Lens culinaris Medik.)是一种冬季豆类作物，其种子中蛋白质含量约为21-31%，总碳水化合物含量为43.4-69.9%，脂肪含量为0.7-4.3%，纤维含量为5.0-26%，灰分含量为2.2-4.2%，对人类具有相当的营养价值(Joshi et al.， 2017)。此外，像任何豆科作物一样，扁豆种植可以分享农业生态系统的可持续发展。它的种植在氮循环中起着至关重要的作用，因为它可以从周围大气中生物固定约85%的所需氮，14.39%的氮来自土壤源(Gan等人，2016;Kabir等人，2019)。在埃及，统计数据显示，2017年扁豆产量仅为480吨，来自235公顷(≈580.7公顷)的收获面积(粮农组织统计司，2019年)。

Drought stress is the primary restricting factor of crop productivity in Egypt. The development of drought-tolerant lines is urgent. However, drought tolerance is a complex trait. So, this work aimed to reveal the genetic background and gene effects controlling of yield parameters and to discover the epistasis in two bread wheat crosses; Sakha 93 × pureline 5 and Gemmeiza 10 × pureline 42 under irrigated and drought conditions, utilizing seven generations viz. P1, P2, F1, BC1, BC2, F2 and F3. Genetic analysis revealed that additive and dominance effects are involved in the genetics for most traits in both crosses and conditions. Both additive x additive and additive x dominance effects were significant in most cases, supporting the presence of duplicate type of epistasis. Therefore, early generation selection would have failed. F1 hybrids (Drought susceptibility indexes were 0.278 in cross I and 0.295 in cross II), were less affected by drought stress conditions, displaying the presence of heterobeltiosis for drought tolerance. Broad-sense and narrow-sense heritabilities and genetic advance ranged from moderate to high for most of the studied traits and these two crosses could be selected to produce high yielding lines under drought conditions.

Sugar beet (Beta vulgaris L.) is the second source of sugar around the world after sugar cane. Two field experiments were carried out in the Research Farm , Faculty of Agriculture, Sohag University, in two successive seasons of 2016/2017 and 2017/2018 to study the effect of Nano-micronutrients fertilizer on yield and quality of sugar beet varieties under normal and late sowing conditions. The results showed the early sowing at 21st October increased the root, quality, sugar and root yields comparing with the late sowing at 21st November in both seasons. the foliar application at 60 days after sowing exhibited the higher values of all studied traits comparing with both of foliar application at 105 days and non-fertilizer in both seasons. The four sugar beet varieties (Nabila, Karta, Kosmas and Tesla) differed significantly on all studied traits in the two seasons. Tesla variety was superior than the others of all studied traits. The highest sucrose % (18.32 and 18.42 %) and sugar yield (5.20 and 5.83 ton/fed) were obtained from Tesla variety with Nano-fertilized at 60 days from sowing of early sowing in 21st October in 2016/2017 and 2017/2018 seasons respectively. According to principal component analysis, the most appropriate sugar beet varieties for selecting of sugar yield was Tesla variety under the most treatments of foliar Nano- micronutrients in the two environments (stable genotype and recommended for the test environments), especially under D1 (sowing at 21 October ) and F2 (spraying time of 60 day after planting).
