The fiber properties of the studied varieties on HVI and Nep tester instruments were made at Cotton Arbitration and Testing General Organization (CATGO) and measure the efficiency qualities of spinning yarn varieties for 3 yarn counts at Delta company (20 - 30- 40 ’S for cotton varieties Giza 95 and Giza 90) and (50 - 60- 70 ’S for Giza 94 and Giza 86) and (60 - 90- 120 ’S for Giza 96 and Giza 88)).  The mean squares of cotton varieties for all studied fiber properties were highly significant differences as well as the two growing seasons mannered the same trend for all studied fiber properties as cotton varieties except fiber length, fiber elongation, short fiber index and neps count revealed insignificant differences.The interaction between six Egyptian cotton varieties and two growing seasons was recorded as highly significant for all studied fiber properties except for two traits fiber elongation and trash area. The yarn properties revealed high significance for the yarn traits of Giza 94 and Giza 86 for three yarn counts (50 - 60- 70 ’S).

Results reflected obvious differences among the six genotypes of cowpea for most of the studied characters. The coefficient of variation (C.V.) was less than 10 % for all the studied traits in all genotypes of cowpea. These results indicate that the six genotypes of cowpea are genetically identical concerning these traits. Analysis of variance showed that variances of genotypes were highly significant in all studied traits. These findings refer to that there were highly variations between genotypes under study. Generally, the data prove that all of the studied traits could be improved through the selection method, but with different degrees of the improving depending upon the amount of variation present in each population. Meanwhile, mean squares of years were significant only in height of the first flower, this can be interpreted as this property being affected by the different environmental conditions in both years of the study. Cluster analysis, based on RAPD plus ISSR analysis, divided the 6 studied genotypes into 3 major groups. The first contained Geza and Kareem7 Cvs. with similarity of (30%), the second consisted of Fowa Lr. and Kaha Cv., and the third one contained the ones of Behira Lr. and Kafr Elshikh Cv.","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90759165","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}
