The experimental design was laid out using randomized complete block design with four replicates. Maize hybrids were significantly differed in all traits studied in both seasons, except grain oil percentage. The variety S.C 128 exhibited the highest days to maturity, while the lowest ones was T.W.C 321 in both seasons as compared with other tested hybrids. The variety T.W.C 321 significantly surpassed other tested hybrids in mean values of grain yield /fed and relative grain yielding ability, while T.W.C 324 and T.W.C 329 gave the lowest mean values in both seasons. Concerning grain quality, S.C 131 and S.C 2031 recorded the highest mean values of oil yield/fed, Meanwhile, T.W.C 321 and S.C 2031 surpassed the other hybrids in mean values of protein percentage and protein yield/fed in the both seasons. It could be summarized that the best hybrid was T.W.C 321 when planting maize in late sowing, where it produced grain yield more than other S.C 131, S.C 2031, S.C 10, S.C 128, T.W.C 324 and T.W.C 329 hybrids by 2.74, 3.08, 4.85, 4.89, 21.40 and 24.96%, respectively as an average of both seasons.","PeriodicalId":215483,"journal":{"name":"Menoufia Journal of Plant Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128667842","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 obtained results point out that, growth parameters (plant height, number of shoots and leaves/plant and stem thickness, shoot fresh and dry weight and total green color) as well as the leaf mineral contents were significantly increased when buttonwood seedlings were watered every four days than when they were watered every eight days in both season. Conversely, leaf proline content was increased under irrigation every 8 days. in addition, adding hydrogel at 0.4 or 0.6 caused a significant increase in the previous growth aspects but decreased leaf proline content compared to the control. Both low irrigation period (4 days) or high of hydrogel rate (0.6% w/w) and their interaction gave the highest values of leaf total and free water contents as well as bound water and osmotic pressure were reduced.

This investigation was carried out to estimate heterosis, combining ability, proportional contributions, genetic components and heritability estimates of some characters for six Egyptian cotton varieties as lines i.e, Giza 90, Giza 95, Giza 86, Giza 94, Giza 92 and Giza 96, while, the other five genotypes used as testers were Karshenky, Suvin, Australy 13, Pima S7 and Pima S6, using line x tester analysis. In 2018 season a randomized complete blocks design with three replications was carried to evaluate all genotype (eleven parents and their 30 F1s crosses) for some genetic parameters. The results indicated that mean squares due to the genotypes, parents, crosses and parents vs. crosses were significant and highly significant for all traits studied, except No. of bolls/plant in the parents, lint percentage in the crosses and fiber strength in the crosses and parents vs. crosses. The mean squares due to lines were significant for all studied traits. Mean square for testers and Line x Tester were significant for most traits studied. The following crosses demonstrated the best heterosis relative to midand better-parent, i.e, Giza 95 x Karshenky, Giza 95 x Australy 13 and Giza 95 x Pima S7 for most traits studied, while the following crosses demonstrated the best heterosis relative to midand better-parent for most studied yield traits, i.e. Giza 90 x Australy 13 and Giza 86 x Karshenky.
