“…The mean value obtained is 4.07, with variant values and standard deviations of 0.218 and 0.467, respectively. This aligns with studies by Akos et al (2019), Dar et al (2021), andAhmad et al (2022) that found that selecting quality rice seed varieties can increase crops' resistance to abiotic and biotic stress. Increasing crop resistance to various stresses positively impacts productivity, thus increasing farmers' income and food security.…”

“…Thus, introducing varieties that tolerate abiotic stress through mutation breeding is one of the most efficient approaches (Ahmad et al, 2022). A study by Mokhtar et al (2012) focused on the MR276 and MR219 varieties and found that MR276 showed better resistance than MR219 in a two-week flood situation.…”

Farmers’ use of subpar rice seed has a substantial impact on the production of rice harvest since it may result in the spread of disease and pests, the incapacity of crops to adapt to climate change, poor soil quality, and bad plant structure. In this context, the situation mentioned earlier has a detrimental impact on farmers' financial earnings as well as an escalation in expenses related to input procurement and crop management, thereby influencing the overall welfare of farmers. Therefore, this study was carried out to identify the selection of rice seed varieties within five seasons of cultivation among farmers and the effect of using quality rice seed varieties on rice cultivation activities. The study employed the descriptive quantitative research approach, and the survey instruments were administered to a sample of 95 rice farmers residing in the AFO F-IV Sungai Limau MADA area, Yan, Kedah. The results of the study found that most respondents used the MR297 rice seed variety for each planting season due to their confidence in the agronomic characteristics of the variety. The findings also indicate the impact of using quality varieties recommended by agricultural agencies. These include increased production, crop tolerance to weather factors, higher resilience, and resistance to disease attacks. This situation has real impacts, including increased farmers' income, lower costs of purchasing production inputs, and farmers’ well-being. This has several consequences for technological advancements in creating high-quality rice seed varieties and their usage by farmers, which can boost rice output, the economy, and the well-being of the farmers, in addition to assuring the security of the nation's rice supplies.

Rice, a staple crop that feeds more than one-third of the world’s population, encounters a wide range of biotic and abiotic stresses due to climate change. Rising temperature is one of the significant abiotic stresses affecting rice productivity worldwide. The development of heat-tolerant rice cultivars is critical in this regard. Weedy rice could potentially serve as a natural resource for genes conferring agronomically important traits beneficial to cultivated rice. However, heat tolerance in both cultivated and weedy rice is still understudied. This study screened a set of 180 weedy rice accessions for heat stress tolerance and further characterised them using genome-wide single-nucleotide polymorphisms (SNPs) analysis. Five heat-tolerant (HT) accessions (MU244, MU235, MU249, MU260 and MU237), along with five heat-susceptible (HS) accessions (MU100, MU114, MU264, MU251 and MU005), were subjected to relative electrical conductivity (REC) test and reactive oxidative species assay (ROS). These tests verified that the five HT accessions performed better under heat stress than their HS counterparts. In addition, whole-genome sequences of three HT (MU235, MU237 and MU066) and four HS (MU100, MU114, MU022 and MU005) accessions were selected for the genome-wide SNPs comparison, revealing substantial amino acid variation in the heat-tolerance-related genes between the HT and HS rice groups. The proposed genes and genome-wide SNP markers may help rice breeders better understand how different rice cultivars respond to heat stress.
