The gene size   for Coptodon zilliii,Oreochromis aureus, and Oreochromis niloticus was (439, 326 & 473 bp long (amplified Cytb gene)), respectively.

In each of the species Oreochromis aureus and Oreochromis niloticus, the research identified two types of unique haplotypes, one in Khaur Abdallah and the other in Shatt-Al-Arab. However, three haplotype patterns for Coptodon zilliii populations were discovered: one in the Shatt al-Arab River and two in Khaur Abdallah. Low nucleotide (π) and haplotype diversity (Hd) values were found in both Oreochromisaureus and Oreochromis niloticus populations in the Shatt Al-Arab river and Khaur Abdallah, indicating low genetic variation among populations for both species in the two regions. However, there was no diversity within the Oreochromis aureus population in both Shatt Al-Arab and Khaur Abdallah. The population of Oreochromis niloticus has the same indication. Three haplotypes for Coptodon zilliii indicate to genetic variance across populations in the Shatt Al-Arab riverand Khaur Abdallah regions, although no variety within the Coptodon zilliii species was found in the Shatt Al-Arab river.

The results also showed the effectiveness of the combination of IAA (1 mg L-1 ) + BA (0.5 mg L-1 )  increasing the number and length of shoots  (6.50 shoot plant-1 and 4.83 cm for Provento and Rivera cultivar). A decrease in the number of roots was also observed with increasing concentrations of BA which added to the medium with or without of IAA. Results also recorded the highest average of diameter and weight of minitubers was 8.63 cm and 3.64 g for the mother plants of the Riviera and Provento cultivars, respectively, while the mother plants and in vitro  propagated plants of three cultivars did not differ in the average number of minitubers.","PeriodicalId":101768,"journal":{"name":"University of Thi-Qar Journal of agricultural research","volume":"263 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125382568","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}
