In muhipeint regional test, the average yield of Longli 1 was 2 100. （30 kg/hm2, which was increased by 9.6% compared to Jingle qulnoa. Langli 1 was a mid-late mature quinoa variety. The plant was brcom-shape, with the plant height of 181.2 - 223.6 cm, the growth period of 128 - 140 d, and the branch number of 23 - 27. The seeds were round pill shaped, with 1 000-grain weight of 2.40 -3.46 g. The contents of crude protein, fat, proline and total phosphorus in seeds were 171.5 -187.8, 56.5 -59.3, 5.5 -6.9 and 4.5 -6.8 g/kg, re- spectively. I_ongli 1 presented resistance against downy mildew and leaf spot, with strong disease-resistant ability. In multipeint regional test and production test, Longli 1 displayed lodging resistance with strong regeneration ability. It also presented resistance to cold, drought, saline and alkaline, and barren, with wide adaptability. Longh 1 was suitable for planting in mountains, plain field and irrigation area with frost-free period greater than 120 d, rainfall more than 250 mm, and altitude 1 500 -3 000 m. The application prospects of quinoa were also put forward in the paper.展开更多

Previous studies have shown that soybean varieties with dwarf features and a short petiole often exhibit a compact plant architecture which could improve yield through increased planting density, although previously reported short petiole accessions were ultimately not usable for breeding in practice. Here, we established a method to assess petiole length and identified an elite mutant line, M657, that exhibits high photosynthetic efficiency. The agronomic traits of M657 were evaluated under field conditions, and appeared to be stable for short petiole across seven locations in northern, Huang–Huai, and southern China from 2017 to 2018. Compared with the Jihuang 13 wild type, the mutant M657 was shorter in both petiole length and plant height, exhibited lower total area of leaf, seed weight per plant and 100-seed weight, but had an increased number of effective branches and the growth period was prolonged by 2–7 days. Using M657 as a parental line for crosses with four other elite lines, we obtained four lines with desirable plant architecture and yield traits, thus demonstrating the feasibility of adopting M657 in breeding programs for soybean cultivars of high density and high yield.展开更多

It is an early-maturing variety with wide adaptability,high yield,and good commercial breeding. The plant has strong growth vigor and high resistance to white powder mildew. The first fruit sets on the 4 ^th-5^ th section,and the fruiting ratio of cucumber is 60%-80%. The cylindrical fruit is about 30-35 cm in length,3. 2-3. 5 cm in diameter with light green skin and glossy appearance. This plant has demonstrated adaptability in early-spring and late-autumn planting as well as spring and autumn tunnel planting.展开更多

The requirement for new olive varieties increased markedly during the last 100 years as a result of a worldwide transformation changing from a traditional extensive to a modern intensive mechanized industry. The traditional olive cultivars still widely used are selections from the local autochthonous cultivars which are well adapted to their natural environment. However, the level of production of those is usually rather low and many of them failed to respond enough to modern intensification methods. The wild olive population is gradually diminishing in all regions thus, natural selection is not efficient enough for developing the cultivars required for the new intensive olive industry. Cross breeding between cultivars with specific characters became the basis for the required new cultivars. The genetic diversity in progenies of most olive cultivars is extremely wide and thus becomes the basic source for breeding of the needed new cultivars. However, the genetic information on olive heredity and identification of specific gene characteristics is still limited. Genomic information is required for rational choice of genitors in accordance with each breeding aim, particularly as most criteria required for the new varieties are of multi-gene nature. The availability of advanced genomic information will also serve as basis for molecular engineering when accepted for use in the olive commodity. Geographically isolated olive populations developed during generations of inbreeding in remote regions are another important genetic resource of characters required for breeding the cultivars for the new modern mechanized olive orchards. The use of molecular markers based on AFLP, SSRs, DArT and SNPs is important for the choice of genitors leading to a reduction of the progeny size required in olive breeding. Presently the newly released olive cultivars are still the result of classical breeding.展开更多
