Post-mining lands, especially abandoned gold mining areas, present serious challenges for agriculture and forage cultivation due to poor soil fertility, heavy metal contamination, and damaged soil structure. To address these issues, this study evaluated the impact of gamma irradiation on the agronomic traits, nutritional content, anatomical characteristics, and in vitro digestibility of dry matter, organic matter, and fiber fractions of Pennisetum purpureum cv. Mott grown on degraded post-gold mining soil. A completely randomized design was used, applying seven doses of gamma rays (0, 5, 10, 15, 20, 25, and 30 Gy). Initially, irradiated plants were cultivated under optimal soil conditions. Selected cuttings were then transplanted onto post-mining soil for two months. Variables observed included growth performance, proximate composition, fiber fractions, macro minerals, and digestibility (dry matter digestibility [DMD], organic matter digestibility [OMD], in vitro digestibility [IVD], neutral detergent fiber digestibility [NDFD], acid detergent fiber digestibility [ADFD], cellulose digestibility [CeD], hemicellulose digestibility [HmD]). Results showed that a moderate dose of 10 Gy significantly enhanced dry matter digestibility, in vitro digestibility, and fiber degradation, accompanied by increases in crude protein and mineral levels. Anatomically, beneficial changes such as thicker mesophyll and vascular tissues were observed at this dose. While the 20 Gy dose also showed improvements in some fiber digestibility parameters, it did not provide an optimal balance with productivity, which was better achieved at 10 Gy. Multivariate analysis revealed distinct treatment clustering, reflecting physiological responses to irradiation. Cultivars treated with 10 Gy exhibited an optimal balance between productivity and forage quality. These findings suggest that gamma irradiation can successfully induce advantageous mutations, improving both adaptability and nutritional value of P. purpureum on marginal soils. In particular, a dose of 10 Gy is promising for breeding superior forage cultivars for the reclamation of post-mining land.

Indonesian sorghum (Sorghum bicolor L.) germplasm with the highest genetic diversity can serve as a valuable resource for developing high-yielding cultivars. Therefore, the present research aimed to obtain information on genetic variability in the population and also determine the key traits associated with grain yield using correlation and path analysis in sorghum F2 population. The sorghum parental genotypes 'Demak 4' and 'Soraya 3', and a local high yielding IPB line, NS 19, NS 109, and NS 111, were used in the crosses. The F2 population was evaluated against parental cultivars and four check genotypes. The results showed that 64 individual plants were observed as transgressive segregants. Meanwhile, the number of leaves and plant height were controlled polygenically through additive genes. The traits of panicle diameter, dry panicle weight, and grain weight per panicle possessed the highest genotypic coefficient of variance. The traits dry panicle weight and diameter were significantly positively correlated with grain yield. The considerable positive correlation with dried panicle weight, panicle length, and diameter could be used as selection criteria. The path analysis reported that the observed agronomic traits explained 97.07% of the total variation in grain weight per panicle.

Sorghum is one of high value commodities for food and energy security due to its wide adaptation. The objectives of this research were to study some genetic parameters of sorghum agronomic traits grown under acid soil conditions and to select aluminum-tolerant sorghum mutant lines. The selection was conducted in an augmented design with 61 lines at the field research station of B2TP-BPPT Lampung. Genetic materials used were mutant lines developed throught gamma irradiation. The results showed that there was significant differences among the mutant lines for some agronomic characters observed. The heritability estimates for agronomic characters were classified as intermediate to high. Selection based on seed weight and biomass production resulted three best sorghum mutan lines i.e ZH30-29-07, ZH30-30-07, and ZH30-35-07. These lines showed the best yield and biomass production under acid soil condition. Key words: sorghum, acid soil, heritability, selection

This research was aimed to develop selection criteria based on correlation and path coefficient analysis. The experiment was carried out at CETROFS (Center for Tropical Fruit Studies) field station of Bogor Agricultural University, Tajur. The result showed that plant height, pseudostem diameter, number of leaves, weeks to harvest, finger number per plant, and mean of finger weight were positively correlated with bunch weight. Pseudostem diameter, number of leaves, finger number per plant have strong direct effect on bunch weight, with path coefficient 0.321, 0.264, 0.297, and 0.722, subsequently. However, the plant height showed strong indirect effect on bunch weight through pseudostem diameter. These characters are useful as a selection criteria for developing new variety of banana with higher bunch weight Key words: path coefficient, selection criteria, banana

High-yielding variety is one of the targets in soybean breeding program. High-yielding variety could be developed through simultaneous selection. Simultaneous selection using selection index was more efficient than selection based on an individual trait only. Objective of the research was to select agronomic characters for construction selection index on 11 soybean populations F6 generation based on correlation analysis, path analysis, and heritability. The correlation analysis showed that number of branch, number of total nod, number of filled pod, number of unfilled pod, number of total pod, and percentage of filled pod have positively and significantly correlated with yield per plant. Based on path analysis, characters number of branch, number of unfilled pod, and number of filled pod have positive direct on yield per plant. The result also showed that number of filled pod has maximum positive direct effect on yield per plant. Generally, number of total nod, number of filled pod, number of total pod, and percentage of filled pod have higher heritability than other characters. Key words: Soybean, correlation, path analysis, heritability, selection index

A study was conducted to reevaluate 15 upland lines previously selected in a field experiment and nutrient culture experiment or tolerance to aluminum toxicity and potassium efficiency in the plastic house of Center for Crop Improvement Studies, Tajur, Bogor. The experiment was conducted in pot culture using Red Yellow Podzolic soil from Jasinga, Bogor. Two level of AI stress (no AI stress and AI stress with pH 4.8, Al saturation 80%, and exchangeable Al 16.6 mei/IOOg) and two levels of potassium fertilizer (6 kg K2Olha and 60 K2Olha) were applied. The study showed that the upland rice lines performed poorer under AI-tress condition compared to under non stress condition in plant heigl at harvest, total number of tiller, number of productive tiller, length of spikelet and grain weight/pot. The performance of the upland rice lines was also significantly different under different level of potassium fertilizer in total number off tiller and nun1ber of productive tiller. Lines that showed significant difference in its performance under AI-stress and non stress condition were consiidered as tolerant lines. The result showed that Lalantik Bamban, Sigundil,CT65 I 0-24-3- I, Hawara Bunar, Ketombol, and Grogol were classified as AI-tolerant and K-efficient lines. Key word: Upland rice, Aluminium, Potasium

Anther culture provides rapid route in obtaining pure lines in a single generation through producing green haploid plants that may be spontaneously doubled. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of eight F1s derived from crossess between upland and new plant types of rice and from their four parents through anther culture. Completely randomized design with 25 replications was used in this research. Treatments consisted of four parent lines/varieties i.e. P1 (Fatmawati and BP360E-MR-79-2), P2 (Fulan Telo Gawa and Fulan Telo Mihat) and eight F1s obtained from reciprocal crosses of P1 and P2. Callus induction medium was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1 kinetin + 10-3 M Putrescine, while regeneration medium was based on MS + 0.5 mg L-1 NAA + 2.0 mg L-1 kinetin + 10-3 M Putrescine. The result indicated that F1 derived from Fatmawati x Fulan Telo Gawa (5.00% green plants per total anther) and their reciprocal (3.80% green plants per total anther) crosses were the most responsive genotypes in rice anther culture (had high anther culture ability). The F1 genotypes were more effective to produce green and doubled haploid plants in rice anther culture than their parents. From this research, 161 double haploid plants (29.81%) from total acclimated green plantlets were obtained. Keywords: anther culture, upland rice, new plant type of rice

A study on physiological mechanism of sorghum to aluminum (Al) toxicity and phosphorous (P) deﬁ ciencies was conducted using several sorghum genotypes in rhizotron. The study was conducted in the greenhouse of the University Farm, Bogor Agricultural University from August to October 2009. The experiment was carried out as a Factorial experiment in a Completely Randomized Design with three replications. The ﬁ rst factor was sorghum genotypes consisted of Numbu (tolerant) and B-75 (sensitive), and the second factor was combination of lime and phosphorous fertilization consisted of: no lime-no P (R1), no lime-low P (R2), no lime-sufﬁ cient P (R3), lime-no P (R4), lime-low P (R5) and lime-sufﬁ cient P (R6). The results showed that all variables were signiﬁ cantly affected by the interaction of media and genotype, except for length of shoot and total P uptake. Under low P and Al toxicity, sorghum variety Numbu showed a higher nutrient efﬁ ciency than B-75 with ability of forming greater dry mass. The sensitive genotypes showed a higher nutrient uptake but a lower P nutrient use efﬁciency under Al toxicity and P deﬁ ciency. Total P uptake and P nutrient use efﬁ ciency were highly correlated with root growth and dry material accumulation. Keywords: sorghum, Al toxicity, P deﬁ ciencies, P nutrient use efﬁ ciency, P uptake

The objective of the research was to identify RAPD markers linked to QTL related to agronomic traits of soybean under low-light intensity condition. The genetic material used in the QTL analysis based on RAPD Markers were Ceneng, Godek, and F6 RILs derived from hybridization between Ceneng (tolerant parent) and Godek (sensitve parent). The results of molecular analysis showed that 9 primers were polymorphic and linked to the tolerant parent. Primers produce 14 RAPD markers which were polymorphic and linked to the tolerant parent. The markers were distributed into a linkage group that containing seven markers. RAPD Markers (OPE15-800, OPM20-800) were linked to two QTL controlling number of productive node and seed weight, respectively. The marker linked to the tolerant parent could be used as a marker assisted selection for high-yielding soybean lines under low-light intensity
