“…Sari et al (2019) and Akshaya (2020) reported that the plant height on grain yield had a high positive indirect effect through flag leaf length. However, Afrin et al (2017) reported negative indirect effects through days to fifty50 per cent flowering, panicle length, plant height and the number of productive tillers per plant.…”

“…Traits such as RI, AVI, AGP, SL, RL, and HSW had a high genetic advance as a percentage of mean (GAM) coupled with high heritability. High heritability plus high genetic advance would be the best genotype selection indicators ( Afrin et al., 2017 ). Thus, these traits should be given highest priority in improving anaerobic germination potential during crop breeding programs.…”

Direct-seeded rice (DSR) is a promising alternative to the traditional puddled rice system. It has become more popular among rice growers as a result of socioeconomic shifts and global climate change. Although DSR offers advantages, rice plants experience greater anaerobic stress at sowing from unpredicted rainfall. Rice is unique among cereals in its ability to germinate under anaerobiosis. The coleoptile of rice rapidly elongates above the water surface to obtain more oxygen and enhance vigorous seedling growth. A panel of 115 landraces and four check varieties were subjected to anaerobic stress with a water level of 10 cm for up to 15 days. The present study observed significant variation in anaerobic germination percentage (AGP) (10%–100%) and anaerobic vigor index (AVI) (150–4,433). Landraces Karuthakar, Poovan samba, Mattaikar, Edakkal, Manvilayan, and Varappu kudainchan were identified as genotypes tolerant to early water submergence. The shoot and root length of susceptible landraces were significantly lower than the tolerant landraces under hypoxia condition, implying that landraces with longer shoots and roots had a higher survival rate. The response index substantiated this. The results clearly show that tolerant and moderately tolerant landraces possessed higher mean values for root and shoot lengths than susceptible landraces. The landraces grouped under the long–bold category had superior AGP and AVI scores to other grain type groups. This raises the possibility that differences in kernel breadth, which is linked to grain type, could affect anaerobic germination potential. Molecular confirmation using gene-specific markers, viz., DFR, TTP_G4, RM478, RM208, and RM24161, for which the polymorphic information content (PIC) value ranged from 0.36 (RM478) to 0.68 (RM206) suggests that this diverse panel of landraces must be assessed further using advanced molecular tools to precisely clarify the genetic mechanism behind this phenomenon. The tolerant landraces thus identified may become donors in breeding programs. The introduction of these traits would contribute to the development of rice varieties tolerant to anaerobic stress, resulting in sustainable yields. This solution could promote the DSR system across the world.

“…It highlighted the potential of low-cost methods to increase flood tolerance and productivity in flood-prone regions. Afrin et al, (2017) evaluated morphological and production traits in submergedtolerant rice genotypes, identifying traits positively correlated with production. It suggested breeding submerged-tolerant rice genotypes as a promising approach for improving yield.…”

This internship reported titled as “The effect of Aminocyclopropane Carboxylic acid (ACC) and Silver Nitrate (AGNO3) on green super rice seedlings for submergence tolerance” aimed to identify submergence tolerant rice genotypes and the role of two chemicals i.e. Aminocyclopropane Carboxylic acid (ACC) and Silver Nitrate (AGNO3) in enhancing submergence tolerance of rice. The trial comprised a pot experiment that was conducted at the experimental field of National Agriculture Research Council (NARC) to evaluate the effect on various newly developed lines of green super rice for submergence tolerance. The experiment was designed in randomized complete block within three replications. The treatments consisted of eleven rice genotypes and two chemicals. Five plants of each genotype were transplanted in to pots which were then treated with ACC, AGNO3 or control (without any chemical). Both these chemicals were applied after one week of transplantation. The data were collected before submergence, after seven days of submergence and after fourteen days of submergence on various agronomic parameters including plant height, leaf length and number of leaves. The results indicated that plant height of genotype NRPC-7 resulted in the tallest plants among all the tested genotypes. Greater leaf length was observed in NRPC-9 in control treatments while maximum number of leaves under the treatment of ACC was observed in genotype NRPC-8. It was concluded that the above-mentioned genotypes were highly tolerated to submergence and can be used in breeding program for submergence tolerant variety development
