ABSTRACT.
The potato crop (Solanum tuberosum L.) is of great importance in the Uruguay economy, being the major vegetable in volume of trade. Uruguay imports some amount of potato seed annually. The National Institute of Agricultural Research (INIA) has been engaged for the last decades to obtain cultivars more adapted to country agroecological conditions, easier to multiply locally for replacing imported seed cultivars such as 'Chieftain'. In this sense, promising cultivars including 'INIA-Iporá' were developed. The objective of this work was to study the morpho-physiological and yield modifications of two potato cultivars ('Chieftain' and 'INIA-Iporá') under different irrigation managements. The experiment was carried out during 2006 and 2007 growing seasons under a rainout shelter, at the Experimental Station INIA Las Brujas, in Uruguay. These two varieties were studied under two irrigation managements: (i) irrigated treatment (2003/04 rainfall + irrigation according to daily crop ETc) and; (ii) deficit irrigated treatment (2003/04 rainfall + one irrigation of 25 mm when the accumulated maximum daily crop evapotranspiration reached 90 mm). The maximum daily crop evapotranspiration was estimated using the FAO Penman-Monteith equation. The experimental design was a completely randomized split plot. The leaf area index, the total plant photosynthesis and the crop yield better responded to the irrigation regime. The two potato cultivars showed differences in length of growing season, leaf area, number of mainstems, plant height and plant transpiration rates. The yield components were modified by the irrigation managements, and differences in commercial yield and total number of plant tubers were observed between the 'Chieftain' and 'INIA-Iporá' cultivars.

ABSTRACT.
Heat stress negatively impacts the reproductive performance of dairy cows. The main objective of this study was to dissect the genetic basis underlying dairy cow fertility under heat stress conditions. Our first goal was to estimate genetic components of cow conception across lactations considering heat stress. Our second goal was to reveal individual genes and functional gene-sets that explain a cow?s ability to conceive under thermal stress. Data consisted of 74 221 insemination records on 13 704 Holstein cows. Multitrait linear repeatability test-day models with random regressions on a function of temperature?humidity index values were used for the analyses. Heritability estimates for cow conception under heat stress were around 2?3%, whereas genetic correlations between general and thermotolerance additive genetic effects were negative and ranged between ?0.35 and ?0.82, indicating an unfavorable relationship between cows? ability to conceive under thermo-neutral vs. thermo-stress conditions. Whole-genome scans identified at least six genomic regions on BTA1, BTA10, BTA11, BTA17, BTA21 and BTA23 associated with conception under thermal stress. These regions harbor candidate genes such as BRWD1, EXD2, ADAM20, EPAS1, TAOK3, and NOS1, which are directly implicated in reproductive functions and cellular response to heat stress. The gene-set enrichment analysis revealed functional terms related to fertilization, developmental biology, heat shock proteins and oxidative stress, among others. Overall, our findings contribute to a better understanding of the genetics underlying the reproductive performance of dairy cattle under heat stress conditions and point out novel genomic strategies for improving thermotolerance and fertility via marker-assisted breeding.
