VARIABILTY AND STABILTY OF TUBER YIELD OF JERUSALEM ARTICHOKE (Helianthus tuberosus L.) / VARIABILIDAD Y ESTABILIDAD DEL RENDIMIENTO DE TUBERCULOS DEL TOPINAMBO / VARIABILITÉ ET STABILITÉ DU RENDEMENT DU TUBERCULE DE TOPINAMBUR

SUMMARYThe objective of this paper was to estimate the genetic and ecological variation as well as the stability of tuber yield per plant, tuber number per plant and tuber size of Jerusalem artichoke based on the results of a variety trial carried out with 20 different Jerusalem artichoke varieties during the period of 1994-2000. Significant genetic as well as ecologycal variation was observed for all of the traits studied. The most promissing varieties showing high tuber yield combined with high yield stability were “BT-4”, “Violet Rennes” and “UKR 4/ 82”. It is encouraging that the highest yielding varieties exibited a rather stable performance over environments.

SUMMARYPotato is an important source of food and income in the highlands of East Africa. Identification of superior genotypes for improved agronomic characteristics will enhance tuber yield. Seven promising clones from population B potato selections (quantitative resistance to late blight) obtained from the International Potato Center, two genotypes from population A (qualitative resistance) and three control cultivars were evaluated for three cropping seasons at four locations in western Uganda in order to determine performance and yield stability. The additive main effects and multiplicative interactive (AMMI) model was used for the analysis. The analysis of variance of yield data for genotypes × locations, genotypes × seasons and genotypes × locations × seasons was significant (p < 0.05) showing the variable response of genotypes and the need for stability analysis. The AMMI statistical model showed that the most stable genotypes were 392618.250 (B5) and 392127.270 (B6) (high yield) and 392618.256 (B1), 391049.255 (B2) and 392127.256 (B7) (low yield) and had negligible interactions with the environments. Across environments, the ranking of genotypes for tuber yield was not consistent. The clones 381471.18 (A2), 387121.4 (A1) and cultivar Victoria had high average yields, but these yields were below average in a few environments. Selective deployment of cultivars can improve tuber yield in the highland tropics.Note: Mention of trade names or commercial products in this publication is solely for the purpose of providing specific information and does not imply recommendation for endorsement by the US Department of Agriculture, Makerere University or Kachwekano Agricultural Research and Development Center.

The Stability

Reports on biased interpretation for the stability of the genotypes under AMMI analysis, considering only the first two interaction principal components, has been observed in recent past. Simultaneous use of yield and stability of genotypes in a single measure had been advocated for identification of highly productive and broadly adapted genotypes. The performance of superiority index, allowed variable weighting mechanism for yield and stability, has been compared with AMMI based measures. For the first year (2018-19) Superiority index, weighting 0.65 and 0.35 for yield and stability, found UAS3002, MP3336 and HI1633 as of stable performance with high yield. Recent analytic measures the relative proportion of genotypic value (PRVG) and Harmonic mean of the relative proportion of genotypic value (MHPRVG) selected CG1029, HI1634 and HD2932 wheat genotypes. Indirect relations were expressed by Superiority Index (SI) with other stability measures. Superiority index saw stable performance along with high yield of HD2864 and HI1634 for the second year 2019-20. PRVG as well as MHPRVG measures observed suitability of CG1029 and HD2864 while MP3336 as unstable wheat genotypes. Values of SI measure had expressed only indirect relations of high degree with stability measures except with yield, PRVG and MHPRVG values. Stability measures by the simultaneous use of AMMI and yield would be more meaning full and useful as compared to measures consider either the AMMI or yield of genotypes only.

Introduction: It is not known precisely the introduction of this species in our country, most research indicates XVI century but there are opinions that consider that this species is present in our country since the Dacian times.Until now has not been cultivated on a large area and it has not been obtained a distinct biological Romanian variety. It can be said that this species has been neglected until now as vegetable crop. This crop gives a high yield in tubers, it grows better in poor soils than most crops, and it is resistant to pests and common plant diseases as well as to cold temperatures (Kosaric, N.,1994). Selection for high yield, inulin content and other economically important traits are useful for improving this crop (Mullin, W. J.,1994). Unlike most crops that store carbon as starch, a polymer of glucose, in the Jerusalem artichoke carbon is stored as inulin, a fructose polymer (Kays, 2007).Aims: The research started in 1996, aimed to obtain biological stabilized and genetically distinct varieties with reduced variability of the main characters, developing specific technology culture in accordance with DUS and rehabilitation of species through the promotion and expansion as vegetable crops in order to revaluate its many uses.Materials and Methods: It was evaluated the local genetic heritage in this species, representing valuable germplasm base composed of 24 genotypes. After purchasing the basic biological material, the evaluated genotypes were collected and 3 of them were detained as progeny. The breeding method used was the clonal selection.Results: The researches were completed with a valuable germplasm collection in this species, were obtained three varieties with distinct characteristics: L1, which shows pink-brown tubers with a tubers yield of over 3.8 kg / plant and a vegetative mass with a height of 2,5 m, L2, white tuber variety with an yield potential of 3.4 kg / plant and a rich vegetative mass with a height of over 2.8 m and L3 that shows pink tubers with an average yield of 2.4 kg / plant and an average plant height of 0.8 m.Conclusion: The research ended with the evaluation of a valuable germplasm collection. Three stabilized genetically varieties with distinct phenotypic characteristics were obtained. Among them, L1 was patented and the other two will be submitted in 2017. It was developed a specific technology for each variety and has been promotional offered improved material to growers with the aim of extending these varieties as vegetable crops.References Kays, Stanley J., and Stephen F.

Columbia Jerusalem artichoke (Helianthus tuberosus L.) exhibited satisfactory tolerance to preplant incorporated applications of ethalfluralin, trifluralin, pendimethalin, EPTC and chloramben in field experiments conducted from 1983 to 1985. Applications of metribuzin resulted in chlorosis and necrosis of leaf margins, and reduced plant height. Yield of tubers did not differ significantly between the hand-weeded and the weedy check plots indicating a high tolerance of Jerusalem artichoke to weed interference.Key words: Helianthus tuberosus L., weed control, crop tolerance, tuber yield

Drought Effects

Abstract Drought sensitivity of potato leads to a reduction in total tuber yield and marketable yield. An investigation of drought effects on tuber yield attributes will facilitate our understanding of how to reduce such huge yield losses. We have evaluated tuber yield, tuber size distribution and marketable yield of a set of 103 European commercial potato cultivars under irrigated and non-irrigated conditions in the field. The multi-year results from two locations, Connantre, France (2013–2015) and Nieuw-Namen in Zeeland, The Netherlands (2013–2014), were analysed. We used Normal and Gamma Distribution models to describe the tuber size distribution of tuber fresh weight and tuber number, respectively. The interactions among parameters of tuber size distribution and total/marketable tuber yield traits were analysed using correlation matrices and biplots. Finally, we used a 14K Infinium SNP marker array to find associations between the parameters or traits and genetic loci on the potato genome. Late foliage maturity facilitated a wider spread of tuber size distribution in favour of larger-sized tubers. Drought effects on total yield were representative of their impact on marketable yield, however, absolute values of total tuber number may not be indicative of marketable number of tubers. We found significant marker-trait associations between a region on chromosome 3 and the spread of tuber number distribution, size class with maximum tuber number and marketable fractions of tuber number and tuber weight. These findings will contribute to improvement and selection for drought tolerance in potato.
