Breeding of sweet potatoes has resulted in a large number of genotypes which generates variation in chemical composition and physical properties. Therefore, such characteristics of 17 sweet potato germplasm accessions and four commercial cultivars originated from Malaysia were evaluated to be able to select them for breeding and food purposes. The starch contents were significantly different (p<0.05) that ranged from 10.67 to 25.40% fresh weight basis (fwb). The purple-fleshed group showed a higher amylose content than those of the orange, white, and yellow-fleshed groups. A variation in sugar contents was also noted and the highest amount of fructose was observed in the yellow-fleshed group, followed by the orange, white, and purple-fleshed groups. However, glucose, sucrose, and maltose could not be grouped according to their tuber flesh colors. The textural properties of steamed tubers considerably varied between sweet potato genotypes. The white-fleshed sweet potato showed the lowest hardness value, followed by the orange, yellow and purple-fleshed genotypes. Moisture, starch, and amylose contents significantly correlated with hardness of the steamed tuber with r = -0.83**, 0.60**, and 0.61**, respectively, while adhesiveness was affected by moisture and amylose contents with r =0.54** and -0.37**, respectively. Springiness had a positive correlation with adhesiveness and chewiness exhibited a negative correlation with moisture content, however, it positively correlated with hardness. Sweet potatoes with low hardness and chewiness are suitable to be used as raw material for juice and jam, while those with medium hardness and chewiness are suitable for products made from mashed tubers. Sweet potatoes with firm texture are tailored for flour preparation, which can be further used for flour-based products. This study reflects a great variation in chemical and physical characteristics of sweet potato genotypes that can be further used for the breeding of improved varieties with desired criteria as well as suitability for particular food products.","PeriodicalId":246741,"journal":{"name":"Buletin Palawija","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123543291","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 availability of high yielding varieties would considerably increase the national soybean production and have a positive impact on farmers’ income and welfare. This study aimed to evaluate selected soybean characters supporting high yield in several genotype crosses. The study was conducted in 2017 using 26 soybean lines derived from crosses among different parents. A randomized block design was used with three replications. The results showed that the soybean lines tested showed differences in days to flowering, days to maturity, plant height, number of branches per plant, number of productive nodes per plant, number of filled pods per plant, 100-seed weight, and seed yield per plot. The lines with the same days to maturity were related to selection process. Seed yield was significantly correlated with the number of productive nodes per plant, and the number of filled pods per plant. The parent of the cross had an effect on the grouping. There were two major groups with Tgm/Anj-773 as a separate group. The highest number of filled pod was achieved by Grb/Lwt-17, while the highest seed yield was noted in Tgm/Anj-773. In addition to the highest seed yield, Tgm/Anj-773 also had early days to flowering, as well as many number of branches, productive nodes and filled pods, thus this genotype is promising to be released as a variety with high yield potential.","PeriodicalId":246741,"journal":{"name":"Buletin Palawija","volume":"236 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123055875","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}

Penelitian ini bertujuan untuk mendapatkan isolat lokal cendawan entomopatogen di Kabupaten Sidrap, Sulawesi Selatan yang dilaksanakan mulai bulan Juli hingga September 2020. Metode eksplorasi yang digunakan adalah isolasi menggunakan sistem pengumpanan serangga (insect baiting). Isolat yang diperoleh kemudian diuji patogenisitasnya pada larva ulat Tenebrio molitor. Hasil eksplorasi dan identifikasi morfologi menunjukkan bahwa seluruh isolat lokal cendawan entomopatogen yang diperoleh mempunyai peluang yang cukup besar untuk digunakan sebagai agens pengendalian hayati. Dua isolat diantaranya yang cukup menonjol, yaitu Beauveria bassiana dan Metarhizium anisopliae memiliki kemampuan membunuh serangga uji T. molitor hingga 80-100% dengan indeks kematian berkisar 5-9 hari. Isolat cendawan M. anisopliae yang diperoleh dari Merittengae lebih patogenik, karena mampu menyebabkan mortalitas T. molitor mencapai 100% hanya dalam waktu lima hari jika dibandingkan dengan isolat lainnya.

That objective of this esearch was to identify the salt-tolerant soybean germplasm accessions. The experiment consisted of two treatments and these were arranged in a randomized complete block design with three replications. The first factor was three soil salinity levels i.e. 1.44-1.72 dS/m (used as a check), 6.75±0.40 dS/m, and 10.48±0.30 dS/m. The second factor was 25 soybean accessions selected from previous salinity screening activity. Parameters observed were soil electrical conductivity (EC), plant height, yield and yield attributes, as well as K, Ca, and Na concentration in soil and plant. The results showed that salinity treatment increased the soil EC, Na concentrations in shoot and root, and reduced K, thereby causing a reduction in soybean growth, seed weight, and seed size. Meanwhile, MLGG 0169, MLGG 0640, MLGG 0767 (Lokon variety), MLGG 1109 (Dega 1 variety), and MLGG 1098 (Detam 2 variety) were identified as tolerant tosalinity level up to 10.48±0.30 dS/m.  The tolerant genotypes were characterized by high ITC index, high seed yield, fewer reduction of seed yield, and mild leaf damage. The tolerances were likely determined by the ability to absorb more K and less Na, translocate more K from root to shoot, and higher K/Na ratio in shoot and root than Ca/Na ratio. It means the K/Na ratio is more important in determining salinity tolerance than Ca/Na ratio. Therefore, accessions can be used as gene source for salt-tolerant breeding, and Lokon, Dega 1, and Detam 2 varieties were recommended for saline soil.","PeriodicalId":246741,"journal":{"name":"Buletin Palawija","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132070893","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}
