Insight Into

Abstract Cotton is an important textile crop whose gains in production over the last century have been challenged by various diseases. Because many modern cultivars are susceptible to several pests and pathogens, breeding efforts have included attempts to introgress wild, naturally resistant germplasm into elite lines. Gossypium stocksii is a wild cotton species native to Africa, which is part of a clade of vastly understudied species. Most of what is known about this species comes from pest resistance surveys and/or breeding efforts, which suggests that G. stocksii could be a valuable reservoir of natural pest resistance. Here we present a high-quality de novo genome sequence for G. stocksii. We compare the G. stocksii genome with resequencing data from a closely related, understudied species (G. somalense) to generate insight into the relatedness of these cotton species. Finally, we discuss the utility of the G. stocksii genome for understanding pest resistance in cotton, particularly resistance to cotton leaf curl virus.

Abstract The high-quality potato seed availability in Indonesia always to be attempted continuously by Indonesian governments to encourage national potato production optimization. One of the efforts is through aeroponic potato seed production. The G0 (zero generation seed) aeroponic potato produces a better yield and healthier tuber compare to G0 conventional potato production. IVegRI has undertaken studies related to G0 potato aeroponic. The results have been disseminated and some of them have been adopted by the potato producers in various regions in Indonesia. The study aimed to investigate the potato aeroponic seed production in Indonesia based on the producers’ perception of the benefits and challenges. The study was conducted from April to December 2017, in 8 districts from 6 provinces, engaging 18 G0 aeroponic potato producers. Data were analyzed descriptively. The resulting study showed that G0 aeroponic producers perceived the production of G0 aeroponic potato as more profitable compared to G0 conventional. The advantages covered: the production was higher, the yield tuber was healthier and sterile, and also it could be produced anytime. Meanwhile, challenges faced were: initially investment cost was quite expensive, electricity installation frequently was unstable and, the challenge concocted a suitable potato aeroponic nutrition.

The technological process of growing potato seed material begins with the acquisition of the source material and its accelerated reproduction to the required volumes. To include new perspective varieties and hybrids in seed programs, they must be released from a viral infection. Exemption from viruses is a responsible, time-consuming and costly process that requires professionalism, but in the absence of this stage, promising varieties cannot participate in the implementation of seed programs. Only in vitro, a material thoroughly assessed with regard to the presence of pathogens, the varietal typicality and severity of the main variety distinctive features can ensure the high quality of seed potatoes in basic seed production.

Enhanced fruit quality, plant health, and productivity are major objectives in apple breeding. The undesirable fruit quality traits frequently associated with pest- and disease-resistant cultivars may be related to resource allocation tradeoffs. The objective of the present study was to evaluate the association between insect resistance and fruit quality in apple. The studied ‘Fiesta’ × ‘Discovery’ apple progeny was characterized by reasonable fruit firmness and optimal sugar content and acidity but small fruit size. There was a positive correlation between codling moth (Cydia pomonella) fruit infestation and fruit firmness. Additionally, a positive correlation was detected between shoot infestation by green apple aphid (Aphis pomi), fruit number as well as sugar content. Infestation by the apple leaf miner moth (Lyonetia clerkella), the rosy apple aphid (Dysaphis plantaginea), the leaf-curling aphid (Dysaphis cf. devecta), and the apple rust mite (Aculus schlechtendali) was not significantly related to fruit quality traits. The positive relationship of increased infestation by some pest insects and quality-determining fruit characteristics such as firmness or sugar content points to a possibly increased necessity for plant protection measures in apple cultivars producing high-quality fruits. One possible explanation of higher pest infestation in cultivars producing fruits with high quality is a tradeoff between resource allocation to defensive secondary metabolites or to fruit quality. By identifying a relationship between pest infestation and fruit quality, the present study highlights the need to consider pest resistance when breeding for high-quality apple cultivars. The use of genetic markers for fruit quality and pest resistance in marker-assisted breeding may facilitate the combined consideration of fruit quality and pest resistance in apple breeding programs.

На основании результатов исследований в условиях дельты Волги на шести отечественных перспективных сортах: Вершининский, Жанна, Евгения, Валентина, Кисловодский и Волжанин (контроль), впервые установлен оптимальный срок летней посадки картофеля – III декада июля с густотой стояния растений от 54,9 до 71,4 тыс/га, обеспечивающий получение высококачественного семенного материала.Determining of the best summer planting time for obtaining the largest number of potato tubers of seed fraction with weight from 40 to 80 g is one of the main tasks of potato seed growing in the Volga delta, since the spring planting is not suitable for potato seed production. The researches were conducted with six domestic prospective varieties: Vershininskiy, Zhanna, Evgenia, Valentina, Kislovodskiy and Volzhanin, taken as a control variant. On the basis of our research, for the first time it was established the optimum summer planting time of potato – the third decade of July with plant density from 54,9 to 71,4 t/ha, ensuring the production of high-quality seed material.

The availability of a high-quality potato seed will affect the increasing of Indonesia potato production. Indonesia Vegetables Research Institute (IVegRI) attempts to produce various high-quality potato varieties. The potatoes are needed to be disseminated to users. Therefore, they could create benefits in terms of increasing farmers' production and revenue. The objective of the study was to identify West Java potato farmers' preference for the seven potato varieties that have been released by IVegRI. The survey was carried out in Garut district, West Java province, Indonesia. Total, 32 potato farmers, participated in the survey from January to September 2019. The Perceived Quality (PQ) was used to analyze data. The result indicates three potato varieties preferred by potato farmers were Dayang sumbi, Sangkuriang, and Medians, respectively. The result would be useful for the IVegRI to create better potato varieties in the future.
