“…Although antioxidants are normally expected to increase in response to stress injury (Purbajanti, Kusmiyati, & Fuskhah, 2017) to counteract the oxidative stress caused by drought (Lum, Hanafi, & Rafii, 2014), by high temperature (Kumar, Shankhdhar, & Shankhdhar, 2016) or by low temperature (Zhang, Chen, Wang, Hong, & Wang, 2014), the results of this study showed that the total antioxidant capacity was mainly cultivar-dependent. Also in previous research (Mukamuhirwa et al, 2018(Mukamuhirwa et al, , 2019, "Mpembuke," "Ndamirabahinzi"…”

“…Although antioxidants are normally expected to increase in response to stress injury (Purbajanti, Kusmiyati, & Fuskhah, ) to counteract the oxidative stress caused by drought (Lum, Hanafi, & Rafii, ), by high temperature (Kumar, Shankhdhar, & Shankhdhar, ) or by low temperature (Zhang, Chen, Wang, Hong, & Wang, ), the results of this study showed that the total antioxidant capacity was mainly cultivar‐dependent. Also in previous research (Mukamuhirwa et al, , ), “Mpembuke,” “Ndamirabahinzi” and “Nemeyubutaka” showed the highest TAC values, indicating the high genetic impact on this character as similar results were found independent of field or biotron cultivation or site and drought treatments.…”

The climate change will contribute drought and temperature extremes to rice growing systems, especially when cultivated in equatorial regions. To evaluate opportunities to cultivate and breed drought‐tolerant rice, seven rice cultivars were evaluated in Rwanda for recurring morphological drought scores, grain yield and components, and quality characteristics. The cultivation conditions, that is site and drought treatment, impacted morphological drought scores, growth and yield attributes, while cultivar affected quality attributes. Thus, site showed a higher impact on grain yield and components than drought and cultivar, with generally a reduced grain yield at the low‐temperature site, as a result of low spikelet fertility. Morphological drought scores were generally increased by drought, while drought at the reproductive stage at the high‐temperature site was negative for yield and its components. The cultivars “Intsindagirabigega” and “Jyambere” were adapted to high‐temperature site conditions. The cultivar “Intsindagirabigega” had the highest amylose content, and “Mpembuke,” the highest antioxidant capacity. Thus, climate change with increased temperature and drought extremes may increase rice productivity in cool areas, while especially drought at reproductive stage will be detrimental in low altitude areas with high temperature. Cultivar variation indicated opportunities for selection and breeding of climate change tolerant rice cultivars which should be of immediate priority.

“…These priming methods, require specific standard methods to validate the moisture stress generated under field conditions (Singh et al, 2017b). Other studies on drought resistance in rice have frequently used indirect selection indicators such as morphological and physiological responses (Fukai and Cooper 1995;Rahman et al, 2002;Yue et al, 2006;Farooq et al, 2010;Kumar et al, 2015;Singh et al, 2017b;Purbajanti et al, 2017). Nevertheless, such indirect selection methods are more labor and resource intensive, as many characters need to be evaluated and the selected tolerant genotypes may not necessarily be high yielding.…”

The purposes of this study were (1) to assess the effectiveness of drought tolerance indices for selection of drought tolerance in upland rice, and (2) to identify the most suitable drought tolerance indices to select for drought tolerant, high yielding upland rice genotypes. This study employed a Split Plot design consisting of irrigation levels as the main plots, and rice genotype as the sub-plot treatments. There were three main plots: 100% field capacity (FC); 75% FC; and 50% FC level. The subplot treatments consisted of 40 upland rice genotypes. Grain yields under no-stress and stressed conditions were used to calculate drought tolerance indices. There were significant variations in grain yields and drought tolerance indices between different rice genotype treatments. The indices from the literature found to be most suitable for the selection of drought tolerant upland rice cultivars were STI, GMP, MRP, HARM, REI, ATI, YI, SNPI. Ten genotypes from among the 40 tested-namely HK-07, ADN-04, PMK-01, ADN-05, NGR-022, ALR-02, HK-06, and KMD-01-were selected as combining drought tolerance with high yield potential.

“…Ionic stress occurs when salt enters the plant reaching toxic levels, and may lead to a reduced ability to maintain water uptake, which is reffered to as the osmotic or water-deficit effect of salinity [3]. Water deficit or drought stress is one of the limiting factors which affect the numerous metabolic procces of crop [4]. Increasing salinity stress from 4 to 7 dS m -1 (1 dS m -1 = 700 mg L -1 ) reduced soybean production by 20 -60% [5].…”

Abstract. Narrow genetic diversity is a main problem restricting the progress of soybean breeding. One way to improve genetic diversity of plant is through mutation. The purpose of this study was to investigate effect of different dose of gamma rays as induced mutagen on physiological, morphological, and anatomical markers during seed germination and seedling growth of soybean. Seeds of soybean cultivars Dering-1 were irradiated with 11 doses of gamma rays (0, 5, 10, 20, 40, 80, 160, 320, 640, 1280, and 2560 Gy [Gray]. The research design was arranged in a completely randomized block design in three replicates. Results showed that soybean seed exposed at high doses (640, 1280, and 2560 Gy) did not survive more than 20 days, the doses were then removed from anatomical evaluation. Higher doses of gamma rays siginificantly reduced germination percentage at the first count and final count, coefficient of germination velocity, germination rate index, germination index, seedling height and seedling root length, and significantly increased mean germination time, first day of germination, last day of germination, and time spread of germination. However, the effects of gamma rays were varies for density, width, and length of stomata. The LD 50 obtained based on survival percentage was 314.78 Gy. It can be concluded that very low and low doses of gamma rays (5-320 Gy) might be used to study the improvement of soybean diversity.
