Maize is grown by millions of smallholder farmers in South Asia (SA) under diverse environments. The crop different seasons a year with varying exposure to weather extremes, including high temperatures at critical growth stages which are expected increase climate change. This study assesses the impact current and future heat stress on maize benefit heat-tolerant varieties SA. Annual mean maximum may 1.4–1.8 °C 2030 2.1–2.6 2050, large monthly, seasonal, spatial variations across extent...
Unpredictable weather vagaries in the Asian tropics often increase risk of a series abiotic stresses maize-growing areas, hindering efforts to reach projected demands. Breeding climate-resilient maize hybrids with cross-tolerance drought and waterlogging is necessary yet challenging because presence genotype-by-environment interaction (GEI) lack an efficient multi-trait-based selection technique. The present study aimed at estimating variance components, genetic parameters, inter-trait...
An association mapping panel, named as CIMMYT Asia (CAAM) involving 396 diverse tropical maize lines were phenotyped for various structural and functional traits of roots under drought well-watered conditions. The experiment was conducted during Kharif (summer-rainy) season 2012 2013 in root phenotyping facility at CIMMYT-Hyderabad, India. CAAM panel genotyped to generate 955, 690 SNPs through GBS v2.7 using Illumina Hi-seq 2000/2500 Institute Genomic Diversity, Cornell University, Ithaca,...
Abstract With progressive climate change and the associated increase in mean temperature, heat stress tolerance has emerged as one of key traits product profile maize breeding pipeline for lowland tropics. The present study aims to identify genomic regions with tropical maize. An association mapping panel, called tolerant (HTAM) was constituted by involving a total 543 inbred lines from diverse genetic backgrounds, test-crossed phenotyped across nine locations South Asia under natural...
Thirty rice genotypes comprising land races, pure lines, somaclones, breeding lines and varieties specifically adapted to costal saline environments were characterized by SSR markers morphological characters in this study. Out of 35 primers markers, 28 found be polymorphic. The PIC value ranged from 0.064 (RM 274) 0.72 580) with an average 0.46. Jaccard’s similarity coefficient 0.42 0.90. At the genetic 56% grouped into five clusters. PCA components explained 41.6% variation. There was...
Abstract Rapid cycle genomic selection (RC‐GS) helps to shorten the breeding and reduce costs of phenotyping, thereby increasing genetic gains in terms both cost time. We implemented RC‐GS on two multi‐parent yellow synthetic (MYS) populations constituted by intermating ten elite lines involved each population, including four drought waterlogging tolerant donors commercial lines, with proven value. Cycle 1 (C ) was based phenotypic top 5% 500 S 2 families derived from MYS test‐crossed...
Abstract Maize is rapidly replacing traditionally cultivated dual purpose crops of South Asia, primarily due to the better economic remuneration. This has created an impetus for improving maize both grain productivity and stover traits. Molecular techniques can largely assist breeders in determining approaches effectively integrating trait improvement their existing breeding pipeline. In current study we identified a suite potential genomic regions associated two major quality...
Erratic rainfall often results in intermittent drought and/or waterlogging and limits maize (Zea mays L.) productivity many parts of the Asian tropics. Developing climate-resilient germplasm possessing tolerance to these key abiotic stresses without a yield penalty under optimal growing conditions is challenge for breeders working stress-vulnerable agro-ecologies region. Breeding stress-resilient rainfed stress-prone ecologies identified as one priority areas CIMMYT-Asia program. We applied...
Spring maize area has emerged as a niche market in South Asia. Production of during this post-rainy season is often challenged due to heat stress. Therefore, incorporating stress resilience an important trait for incorporation hybrids selected deployment season. However, the significant genotype × environment interaction (GEI) effects under stress, major challenge lies identifying genotypes with improved stable performance across locations and years. In present study, we attempted identify...

Climate change is now-a-days a great concern for many scientists, researchers and policy makers as the implications of climate perceived are detrimental adverse to survival mankind.The present environmental on suggests in global climate.The United Nations Framework Convention Change (UNFCC) states that due human activities.The few impacts were warming, melting glaciers, rise sea levels, sub-mergence coastal areas, floods increase frequency heavy rainfalls.The state our understanding even...
Indian summer monsoon rainfall exhibits inter-seasonal variations in the time scales of 2-7 years which are linked to quasi-biennial oscillations and El nino-Southern Oscillation phenomenon also intra-seasonal time-scale 30-60 days activity MJO emerged as a dominant mode addition other modes low frequency oscillations. In this scenario, inter intra seasonal variability 29 meteorological sub-divisional rainfalls has been investigated by correlating indices at 10 different longitudes covering...
Heat stress resilience in maize hybrids is emerging as an important trait germplasm targeted for cultivation the post-rainy season spring South Asia. One of major challenges breeding these agro-ecologies differential response genotypes to heat across locations during season. This study at identifying environmental variables that contributed genotype × (GEI) yield variations observed among grown stress. The trial dataset used this constitutes 46 trials location combinations spread over a...
Most parts of the Asian tropics are hotspots climate change effects and associated weather variabilities. One major challenges with is uncertainty inter-annual variability in conditions as crops frequently exposed to different extremes within same season. Therefore, agricultural research must strive develop new crop varieties inbuilt resilience towards variable rather than merely tolerance individual stresses a specific situation and/or at stage. C4 known for their wider adaptation range...

Being a widely cultivated crop globally under diverse climatic conditions and soil types, maize is often exposed to an array of biotic abiotic stresses. Soil salinity one the challenges for cultivation in many parts lowland tropics that significantly affects growth reduces economic yields. Breeding strategies integrated with molecular approach might accelerate process identifying developing salinity-tolerant cultivars. In this study, association mapping panel consisting 305 inbred lines was...
