“…Subsequently, these genotypes showed higher grain yield at normal terminal drought situation than the grain yield at corresponding irrigated and KI sprayed environments. This is inconsistent with the findings of Zhu et al [17] that increased grain yield in rice varieties tolerant towards lodging.…”

Lodging status of rice is an important consideration for determination of grain yield and acceptability of the genotype among the rice farming community. In this communication, 59 local genotypes of rice were screened for lodging tolerance under three different cultivation environments. Boichi and Seshaphal were found to be highly lodging tolerant under all the three situations. Majority of the local genotypes were reported to be susceptible to lodging. The numbers of highly susceptible local genotypes towards lodging were 55, 29 and 15 at irrigated, drought created by spraying potassium iodide (KI) under irrigated condition and normal terminal drought environments, respectively. Lodging was more frequent in irrigated condition than the normal terminal drought condition or drought situation created by spraying of KI along with normal irrigation. The mean reduction in yield was more in the drought situation created by spraying of KI along with normal irrigation (20.62%) than the normal terminal drought (18.66%). The average lodging susceptibility also reduced in normal terminal drought condition (3.58) as compared to the drought situation created by spraying of KI along with normal irrigation (6.32). It has been reported that in most of the cases lodging caused remarkable yield loss.

“…Structural crop parameters, such as crop height, can also affect the lodging resistance of a variety and have been a central focus of seasonal crop lodging risk management (Pinthus, 1974). In the event of lodging, the plant structure is destroyed such that the stem is inclined at a certain angle, and plant height is reduced (Setter et al, 1997;Murakami et al, 2012;Zhu et al, 2016). Setter et al (1997) reported a reduction of 75% in rice canopy height under lodged conditions, which consequently lowered the photosynthesis rate by 60-80% relative to nonlodged rice.…”

Rapid and quantitative assessment of crop lodging is important for understanding the causes of the phenomena, improving crop management, making better production and supporting loss estimates in general. Accurate information on the location and timing of crop lodging is valuable for farmers, agronomists, insurance loss adjusters, and policymakers. Lodging studies can be performed to assess the impact of lodging events or to model the risk of occurrence, both of which rely on information that can be acquired by field observations, from meteorological data and from remote sensing (RS). While studies applying RS data to assess crop lodging dates back three decades, there has been no comprehensive review of the status, potential, current approaches, and challenges in this domain. In this position paper, we review the trends in field/lab-based and RS-based studies for crop lodging assessment and discuss the strengths and weaknesses of current approaches. Theoretical background on crop lodging is presented, and the scope of RS in assessing plant characteristics associated with lodging is reviewed and discussed. The review focuses on RS-based studies, grouping them according to the platform deployed (i.e., ground-based, airborne and spaceborne), with an emphasis on analyzing the pros and cons of the technology. Finally, the challenges, research gaps, perspectives for future research, and an outlook on new sensors and platforms are presented to provide state-of-the-art and future scenarios of RS in lodging assessment. Our review reveals that the use of RS techniques in crop lodging assessment is still in an experimental stage. However, there is increasing interest within the RS scientific community (based on the increased rate of publications over time) to investigate its use for crop lodging detection and risk mapping. The existing satellitebased lodging assessment studies are very few, and the operational application of the current approaches over large spatial extents seems to be the biggest challenge. We identify opportunities for future studies that can develop quantitative models for estimating lodging severity and mapping lodging risk using RS data. 1.2. The role of remote sensing The past few decades have witnessed considerable growth in the use of sensors on-board Earth-Observation (EO) systems for agricultural monitoring applications. Today, crop biophysical properties such as leaf

“…The brown color of rice seed pericarps is known to be related to the Rc gene, which encodes a trans-acting regulatory factor with a basic helix-loop-helix motif (Furukawa et al 2006). Unlike shattering habit and seed color, lodging habit is affected by quantitative traits such as culm length, culm thickness, culm stiffness, culm fresh weight, and internode diameter (Ookawa et al 2010;Zhu et al 2016). In rice, the semi-dwarf gene, sd1, increases yield by enhancing lodging resistance (Ashikari et al 2002).…”

Previously, we showed that qCdp7, an allele identified in the high-Cd-accumulating indica rice variety 'Jarjan,' is associated with effective phytoextraction of Cd from paddy soils. However, 'Jarjan' may not be practical for phytoextraction because it is susceptible to seed shattering and culm lodging, which are unfavorable traits for mechanical rice harvesting. In this study, to develop a practical rice line for phytoextraction, we introduced the qCdp7 allele into 'Tachisugata,' a rice variety with a nonshattering habit and lodging resistance, to produce a new high-Cd-accumulating rice line designated 'TJTT8.' This line inherited high-Cd accumulation and brown pericarps from 'Jarjan' and a nonshattering habit and lodging resistance from 'Tachisugata;' all of these traits are necessary for rice intended for Cd phytoextraction in Japan. Backcross inbred lines (BILs) were produced by two backcrosses to 'Tachisugata' after a cross between 'Jarjan' and 'Tachisugata.' 'TJTT8' was selected from the BILs by means of markerassisted selection and phenotypic evaluation. When 'TJTT8,' the parents, and 'Cho-ko-koku' which is a high-Cd-accumulating indica variety were cultivated in Cd-contaminated paddy fields in four locations in Japan, 'TJTT8' exhibited lodging resistance and shattering resistance that were higher than those of 'Jarjan' and 'Cho-ko-koku' and equivalent to those of 'Tachisugata.' 'TJTT8' accumulated Cd in the aerial parts of the plants at concentrations ranging from 6.5 to 22.7 mg m −2 : it showed significantly higher Cd accumulation than 'Tachisugata' and was equivalent to 'Jarjan' and slightly superior to 'Cho-ko-koku.' Soil Cd concentration was estimated to have been reduced by 8.7-33.6% based on the amount of Cd accumulation in the aerial parts of the plants. Thus, we succeeded in using the qCdp7 allele to produce a practical rice line for Cd phytoextraction by improving several agronomic traits for compatibility with Japanese cultivation systems.
