“…The low availability of water to plants is due to osmotic stress which causes a reduction in cell elongation and division process therefore by lowering cell growth and the turgor pressure as a result, there is a corresponding decrease in dry mass and biomass. (Farooq et al, 2015;Sagar, 2017;Roy et al, 2018;Ashaduzzaman et al, 2020;Islam et al, 2018). The ANOVA showed (Table 3) significant variance among treatments whereas non-significant among genotypes for seedling height.…”

“…The highest GSTI was found in NRPC 7 (68) and the lowest (10) in NRPC 3 and NRPC 8 at 15% PEG concentration. The water potential in the osmotic solution decreases as PEG concentrations rise because there is less oxygen available for the seed to germinate (Purbajanti et al, 2019;Ashaduzzaman et al, 2020). ANOVA showed (Table 3) significant result among treatments for seedling fresh weight, within treatment significant and between genotypes non-significant.…”

Among various abiotic stresses causing serious impact on crop growth, drought poses a significant reducing stress towards crop yield and its stability over the time and locality. In terms of sensitivity to this environmental stress, rice, which is a drought-sensitive crop, exhibits notable varietal variability. for the estimation of elite coarse rice lines to withstand against the drought stress especially during early plant developmental phases and germination and seedling stage, an experiment was carried out from June to July

“…Germination percentage, vigor index, radicle and plumule length were studied at 4, 6, 8 days after sowing (DAS). Besides these, stress tolerance indices of these variables were also evaluated at 8 DAS using formula stated in Sagar et al, (2019;2020) and Huqe (2021).…”

Aluminium stress is one of the major problems of wheat production that significantly reduces the growth and development. Al toxicity can be recovered by exogenous application of different growth inducing nutrient elements. Thus, this study was conducted to evaluate the ameliaration effect of B under Al toxicity. Therefore, a petri dish and hydroponic culture experiment of wheat was conducted at Crop Physiology Laboratory, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during the period from January 2016 to February 2017 to investigate the effect of boron on amelioration of aluminium toxicity in germination and seedling stage. Both the experiments were designed in completely randomized design (CRD) with three replications. The experiments were comprised of four levels of boron and aluminium concentrations viz., 0 µM B + 0 µM Al (control), 0 µM Al + 40 µM B, 200 µM Al + 40 µM B and 0 µM B + 200 µM Al and five wheat varieties viz; BARI Gom-23, BARI Gom-24, BARI Gom-28, BARI Gom-27 and BARI Gom-30. Results indicated that germination percentage, radicle and plumule length, root and shoot length, leaf length, fresh and dry mass plant-1 were greater in 0 µM Al + 40 µM B treated plants than 0 µM B + 200 µM Al induced conditions. It indicates that wheat seedlings are susceptible to aluminium and boron can ameliorate aluminium toxicity. However, among the studied varieties, the reduction of dry mass under aluminium stress was minimum in BARI Gom-28 followed by BARI Gom-23 indicating BARI Gom-28 was more tolerant to aluminium stress than the other varieties. On the contrary, the varieties, BARI Gom-27 and BARI Gom-24 were more susceptible to aluminium stress. So it indicates that aluminium stress severely affects the growth and developments especially in the sensitive varieties and tolerant varieties have the self-ability to grow and develop even under aluminium stress condition.

“…Some selection methods that can be used to obtain upland rice genotypes that are resistant to drought checks are the use of polyethylene glycol (PEG) solution (Sunaryo et al 2016;Sagar et al 2020), leaf rolling and leaf drying score (IRRI 2013), evaluation of efficiency degree of drought tolerance (DTD Method) (Zu et al 2017). The assessment in the critical period became an efficient selection in obtaining a superior drought-tolerant upland rice cultivar (Adhikari et al 2019).…”

Abstract. Mustikarini ED, Lestari T, Santi R, Prayoga GI, Cahya Z. 2022. Short Communication: Evaluation of F6 generation of upland rice promising lines for drought stress tolerance. Biodiversitas 23: 3401-3406. Water is important in metabolic processes affecting rice crop growth and development. Drought stress can decrease rice production, necessitating the development ofdrought-tolerant varieties. Selection of drought-tolerant can be done during the critical period plant booting phase. Thisresearch aimed to determine promising linesof upland rice tolerant to drought stress. This research was conducted from December 2019 toMay 2020 at the experimental farmofthe Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The research was laid out in a completely randomized design with a single-factortreatment. The treatment was rice genotypes consisting of 10 lines and 2 checkvarieties; each was 3 replicates. The results showed that the droughtstressin the plant booting phase of rice plants significantly affected the plant heigh character of the plant, grains number per panicle, the weight of grain per panicle, the age of flowering, and harvest time, but gave no significant effect on the number of leaves, the number of productive tillers, roots length. The upland rice lines 23A-56-30-25-1, 23A-56-30-25-12, and 23A-56-30-25-13 showed good drought stress tolerance based on leaf rolling, leaf drying, crop yield, and plant growth percentage.
