Eight bread wheat genotypes and their F 1 hybrids were evaluated under drought stress induced by the treatment with Polyethylene Glycol-6000. The studied traits were shoot length (SHL), root length (ROL), number of lateral roots (NOR), fresh weight of seedling (FRW) and dry weight of seedling (DRW). Highly significant (P<0.01) differences were observed among studied genotypes for all seedling traits under drought stress conditions. Highly significant (P<0.01) mean squares due to GCA and SCA effects were observed for all seedling traits, indicating the importance of both additive and non-additive gene actions. Obviously, GCA mean squares were larger in magnitude than that of SCA, indicating the importance role of the additive gene action in the inheritance of the studied traits. Compared to their parents, F 1 hybrids produced longer roots under drought stress conditions, indicating the presence of heterosis. The regression analysis indicated a partial adequacy of an additive-dominance model for ROL, NOR, FRW and DRW, while non adequate model was observed for SHL. Based on GCA effects, the parental genotypes P 1 , P 2 and P 3 were the best general combiners for most studied traits under drought stress conditions. The highest desirable SCA effects were obtained from the crosses P 1 ×P 3 , P 1 ×P 6 , P 1 ×P 8 , P 2 ×P 5 and P 2 ×P 7 for most studied traits, indicating their usefulness as best promising combinations under drought stress conditions.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135646499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, genetic diversity among cultivars was studied using RAPD-PCR molecular marker. Physical characteristics results of the fruit showed significant differences among the tested cultivars. Samani and Magdool showed the highest values for both fruit dimensions and weight characteristics. All 5 tested RAPD primers were able to differentiate among the tested date palm cultivars and showed high polymorphism percentage ranging from 75-100%. Thirteen different specific positive and negative markers associated with some cultivars were obtained. The genetic similarity among cultivars ranged from 40% to 100% and the highest genetic similarity value was observed between Nawashf Red and Nawashf White. The results showed that the cultivars with the same name from different geographical locations are genetically different and showed significant differences in fruit physical characteristics.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135646498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out in randomized complete block design (RCBD) with three replications utilizing a strip plot configuration. The foliar sprays (Control, Indole Acetic Acid, Gibberellin Acid, and Salicylic Acid) were organized vertically, whereas the application times (one, two, and three times) were organized horizontally. In the two growing seasons, the evaluated growth regulators significantly influenced the number of branches plant -1 , 100-seed weight, seed weight plant -1 , and seed yield faddan -1 characteristics. Plants treated with 200 ppm Gibberellin or Salicylic Acid had the highest mean values of the specified attributes in both seasons. The results also demonstrated that the examined application timings had a highly significant impact on all analyzed features in both seasons. Furthermore, growth regulators were applied three times at 30, 60, and 90 days after sowing (DAS), yielding the greatest average values of seed yield faddan -1 (1365.64 and 1373.87 kg in the first and second seasons, respectively)","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135707236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Highly significant differences were found among crosses, lines (L), testers (T), and their interaction for grain yield/plot (GY/P), ear diameter (ED), number of kernels/row (NK/R) and days to 50% silking (SILK). The contribution of L vs. T interaction was higher than lines and testers indicating high estimates of variance due to specific combining ability for NK/R and GY/P. The general mean over all testers surpassed both S1 families and S1 top-crosses for GY/P (414.29 and 77.05%), and only S1 top-crosses for SILK (3.42%). Otherwise, the testers were less than S1 families for SILK (2.84%). Moreover, the S1 top-crosses exceeded the S1 families for GY/P (190.48%). The S1 top-crosses were earlier than both testers (-3.31%) and S1 families (-5.98%). 22, 28, and 26 S1 families possessed positive and significant GCA effects for GYP, ED, and NKR, respectively, and 16 lines with negative and significant GCA effects for SILK.
