The focus of this research was to compare the effect of BAP and Kinetin affected Sweet Charlie strawberry multiplication. The experiment was located at the Seed Technology Tissue Culture Laboratory, Faculty of Agriculture, Padjadjaran University.

This study showed that BAP had a better effect than Kinetin on the number of shoots, number of leaves, and wet weight of strawberry Sweet Charlie cultivar. The addition of BAP was recommended over Kinetin to obtain the highest number of shoots, the highest number of leaves, and the highest wet weight of culture on strawberry Sweet Charlie cultivar.","PeriodicalId":340373,"journal":{"name":"Jurnal Agroteknologi","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122817226","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}

One way to increase the genetic diversity of black rice is by using gamma ray irradiation. This study aims to determine the genetic diversity and heritability value of M2 generation black rice resulting from gamma-ray irradiation. The research was conducted in February - June 2021 at the Screenhouse Universitas Perjuangan Tasikmalaya. The genetic material used was black rice M2 generation resulting from gamma ray irradiation with doses 200 gy and PH5 as a control. The research was conducted in 2 experimental stages. The first experiment was in the nursery where M2 seeds were planted with 1000 seeds and 200 seeds for the control. In the second study, the M2 generation black rice mutant was planted with 250 seedlings without replication and the control 10 plants were repeated three times. The results showed that there was a chlorophyll mutation in the M2 generation lines which produced color variations including albino 0.5%, xantha 42%, viridis 5%, tigrina 0.5%, normal 52% at 21 HSS. The survival ability of the black rice mutant was smaller than that of the control. The heritability values in the broad sense of the high category and high genetic diversity were found in the number of productive tillers, the number of total grain, and the number of empty grain. M2 generation black rice irradiated with 200 gy gamma rays was able to provide a response of longer flowering time, narrower flag leaves, lower weight per plant, less filled grain, and increased number of empty grain compared to control (PH5).","PeriodicalId":340373,"journal":{"name":"Jurnal Agroteknologi","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125657881","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}
