“…Genotype, TCGS-1694 (253.00) showed the highest SLA value and lowest in (Fig 1D). Recent findings were also similar to results of the present study, where a drought-tolerant genotype had higher RW C than the susceptible genotypes (Khar et al, 2022).…”

Background: Drought is a leading abiotic factor limiting groundnut production globally. Therefore, the screening and development of moisture stress tolerant groundnut genotypes is a key issue towards sustainable agriculture. Methods: An experiment was laid in a split plot design taking two conditions, control (T1) and moisture stress (T2) as main treatments and 7 genotypes of groundnut as sub treatments. Several morpho-physiological traits like dry matter production, dry matter partitioning, photosynthetic traits, relative water content, were measured after 10 days of stress imposition. Yield and yield attributes were also recorded at harvest along with drought tolerance index and principal component analysis. Result: Results showed significant differences among the genotypes at moisture stress and control conditions. Significant decrease was observed in chlorophyll content, total dry matter production, dry matter partitioning efficiency, relative water content, photosynthetic traits, except specific leaf area among all the genotypes. TCGS-1694 have been identified as moisture stress-tolerant genotypes in principal component analysis with higher efficiency interms of total dry matter production, photosynthetic rate, dry matter partitioning to pods, stress tolerance index, yield and yield attributes while Kadiri-6 has been identified as susceptible genotype.

“…Drought stress has serious impact on onion production, in order to develop varieties resilient to drought, onion breeders focus on selecting effective germplasm (Gedam et al, 2021). Central Asia is the hub of diversification for the Allium species and breeders' top priority is to create climatesmart cultivars and superclass onion that can withstand abiotic stresses (Khar et al, 2022). Sources of resistance for different abiotic stresses have been presented in Table 7.…”

Onion is a long-cultivated vegetable crop that originated in Central Asia. Almost everywhere in the world, onions are cultivated because of their culinary, nutritional, medicinal and health benefits. Using traditional breeding methods, breeders and farmers have been working to enhance onion yield for years. While it is currently difficult to meet growing customer demand and deal with unfavorable climate conditions. Due to its biennial life cycle, cross-pollination and inbreeding depression, it has been challenging to characterize significant traits. Consequently, the recently available onion genome sequence and the use of contemporary molecular breeding techniques will help researchers to overcome those challenges and speed up the development of the onion crop.

“…The main challenges are the impact of diseases caused by pathogens, such as fungi and bacteria [4,5], as well as the presence of insect pests that affect plant health and bulb quality [6,7]. Moreover, abiotic stress, such as adverse weather conditions and water availability, can negatively influence the growth and development of the onion crop [8,9]. The quality of crops are fundamental aspects to guarantee food safety [10].…”

Indole-3-acetic acid (IAA) is a key plant hormone that plays crucial roles in plant growth and development. This study investigated the effects of exogenous application of IAA as a growth regulator in onion cultivation (Allium cepa L.). Various IAA concentrations were evaluated to determine their effects on onion growth and chemical parameters. Several agronomic properties and chemical parameters, including total fresh weight, plant height, chlorophyll content, nitrates, total phenols, and antioxidant capacity (DPPH), were analyzed. The results revealed that the exogenous application of different concentrations of IAA had a significant impact on onion growth and quality. Specifically, it was found that certain concentrations of IAA fostered a significant increase in fresh bulb weight and a notable elevation in the levels of phenolic compounds. However, the onion’s response to IAA was concentration dependent. In conclusion, the present study offers evidence that the exogenous application of IAA as a growth regulator can enhance onion growth and quality. These findings hold relevance for the advancement of sustainable agricultural practices and can be directed towards crop enhancement.
