Seven different strains of melon (Cucumis melo L.) were tested for their response to Tetranychus urticae. Data revealed that, all plant growth parameters were affected significantly with infestation of T. urticae; leaf area which considered the main source of mite feeding was the most affected one. However, (L5) had the lowest leaf area (24.98 cm2 ) while (L7) recorded the highest leaf area (41.26 cm). Also, accumulated moving stages in (L2) showed the lowest population density with an average of 1.70 individual /in2 during 4 weeks, of season 2016. During season 2017, the highest leaf area was in hybrids (L4×L1) and (L4×L2) with an average 62.93 and 61.86 cm2 . All hybrids explained three levels of infestation; high level was observed in hybrids (L6×L2), (L5×L2) and (L7×L1) and accumulated the population density of moving stages with an average of 80.70, 70.60 and 61.40 individual /in2 . While medium level was recorded in hybrids (L5×L1 and L7×L2) and the third, low level of infestation was recorded in hybrids (L6×L1, L4×L1, L3×L2, L3×L1 and L4×L2) and moving stages average were 2.70, 3.30, 3.70, 3.90 and 5.30 individual /in2 so these hybrids were resistant to infestation of T .urticae . Regarding horticultural characters obtained data on total yield ranged from 4015.0 to 2185.0 g/plant; (L4) gave the highest value of total yield. Estimates of broad sense heritability were high for all studied traits indicating minor role of the environment. The results showed significant and highly significant mean squares for both general combining ability and specific combining ability in all studied traits, indicating the important role of both additive and non-additive gene effects in the expression of these traits. Highly significant SCA effects in all studied traits were recorded for the crosses (L3×L2), (L5×L2), (L6×L2) and (L3×L1).","PeriodicalId":282479,"journal":{"name":"Egyptian Journal of Plant Breeding","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121848052","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}

Six parental faba bean genotypes and their half diallel crosses (15 F1’s) were evaluated under a randomized complete block design in three replications. The results reflected significant differences for both GCA and SCA in most traits, indicating the important role of both additive and dominant components in the inheritance. Meanwhile, Baker’s ratio emphasized the preponderant role of additive gene action in controlling the most studied traits. Simple correlation results showed that seed yield may be raised through selecting most pods and seeds per plant, which recorded the highest heritability in broad and narrow sense (hb 2 and hn 2%) estimates coupled with highest genetic advance (GA %) in faba bean. Biplot graph (innovative) and Griffing (traditional) analysis exhibited equivalent results for gca and sca effects and are meaningful for identifying Giza 843 (P1), Misr 1 (P2) and Giza 40 (P6) as the best parents and Giza 843 x Misr 1 (C12), Giza 843 x Nubaria 1 (C15), Misr 1 x Giza 3 (C24), Giza 716 x Nubaria 1 (C35) and Nubaria 1 x Giza 40 (C56) as promising five crosses. Then, GT-biplot method is considered as the best alternative analysis for giving a complete picture about the interrelationships among genotypes and traits (for relative comparing genotypes based on multiple traits). Hence, number of pods and seeds per plant traits could be used for the improvement of seed yield. Besides, five faba bean crosses were distinguished which possess genetic factors for high yield and highly promising to be employed in the development of high yielding populations of faba bean breeding programs.","PeriodicalId":282479,"journal":{"name":"Egyptian Journal of Plant Breeding","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128851561","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 results indicated highly significant differences among the genotypes, environments and their interaction for all traits under investigation, suggesting that these genotypes were highly variable for almost all traits, therefore, would respond to selection. The Egyptian genotype (Dorado x LC) gave the best performance for most of studied traits under each environment and their combined data. This genotype could be released as a new Egyptian grain sorghum variety after testing in a large scale. The individual and the combined analyses indicated that most genotypes had higher genotypic and phenotypic variance components than the environmental variance, which an indicative that the environment had less effect on the expression of the studied traits; for that is these genotypes may be exploited in breeding programs. The traits which showed high genetic advance as a percentage of mean (Δg %) were plant height, panicle length, panicle width, 1000- grain weight and grain yield/plant. Moderate GCV% and PCV% were also observed for all studied traits except days to 50% flowering and number of green leaves, revealing that the genotypes have a broad base genetic background as well as good potential that will respond positively to selection. The correlation between grain yield/plant and the other studied traits was negative and highly significant for days to 50% flowering and positive and highly significant with the rest of studied traits, which mean that any improving in these traits will directly give improvement in grain yield. The lowest similarity (87.00%) was observed between genotype 5 (ICSR 89016) and genotype 15 (Dorado x LC) which are located in different groups and was located in highly diverged clusters, Therefore these genotypes were found to be a good parents for a hybridization or heterosis breading programs.","PeriodicalId":282479,"journal":{"name":"Egyptian Journal of Plant Breeding","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132894971","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}

Most of yield traits means in F4 generation were higher than F3 generation via the genetic improvement using the selection procedures. Fiber traits means in F3 and F4 generations were almost the same in values which reflect the early fixation of most of the genetic components of these traits. PCV and GCV for lint cotton yield/plant, bolls/plant and boll weight were larger in F2 generation than those of the succeeding generations. Most of the studied traits showed moderate to high heritability in broad sense in all generations except for bolls/plant and boll weight in F4 generation.

Therefore, the present study was conducted to determine salt tolerance of twenty muskmelon recombinant inbred lines (RILs) based on determining of seeds germination rate and percentage in laboratory experiment and measuring of some morphological and horticultural attributes for them in pots experiment under netted house at Horticultural Research Institute\u0002Agricultural Research Centre, Egypt during 2016 and 2017 early summer seasons. These RILs were exposed to four different levels of sodium chloride (NaCl) viz., 0 mM, 50 mM, 75 mM and 100 mM after 15 days from seed sowing. The findings confirmed that the salinity tolerance of any genotype was increased as the reduction or increment rate for this genotype compared to control reduced and vice versa. So, the muskmelon RILs 305 and 307 showed salinity tolerance till 50 mM NaCl and RIL 309 had salinity tolerance till 75 mM NaCl, but none of RILs had salinity tolerance at 100 mM NaCl in all measured traits. Based on these two salinity experiments, these three muskmelon RILs were selected as salt tolerant and were made all the combinations of crosses among them in one direction to produce three F1 hybrids that were grown under greenhouse at Kaha Vegetable Research Farm (KVRF), Kalubia during 2017 late summer season. These three F1s beside their parents and hybrid Gal 23 (used as control) were sown in the two open fields using drip irrigation system at Sadat city, Menofia Governorate, one of them was irrigated with groundwater 955 ppm salinity (used as control) and the other field was irrigated with groundwater 2760 ppm salinity (used as a field dose for salinity tolerance evaluation) during 2018 early summer season.
