Hydration of the endosperm is a critical part of the malting process that ensures proper modification of the grain. However, little is known about the genetic controls of endosperm hydration and its relationship to agronomic and malt quality traits. The extent of endosperm hydration is estimated through hydration index (HYI). We measured HYI, agronomic, and malt quality traits on a 169-line subset of the NSGC Barley Core Panel, which includes global malt lines, some dating from the inception of European breeding programmes. Utilizing GWAS, 61 QTLs were identified for HYI, dormancy, agronomic, and malt quality traits. Of these, six were found to be related to HYI and were located on 1H, 2H, 3H, 6H, and 7H. We found HYI QTLs cosegregating with kernel size and hardness (1H and 3H), malting quality (2H and 6H), and dormancy (2H and 6H). These results indicate that endosperm hydration after steeping can be improved by selecting high HYI alleles on 2H, 6H, and 7H, positively impacting malting quality without negatively impacting kernel size or dormancy. 相似文献

Ascochyta blight, caused by Didymella rabiei, affects both domesticated chickpea and its congeneric wild relatives. The aim of this study was to compare the aggressiveness
of D. rabiei isolates from wild and domesticated Cicer spp. in Turkey and Israel on wild and domesticated hosts from both countries. A total of eight isolates of D. rabiei sampled from C. pinnatifidum, C. judaicum and C. arietinum in Turkey and Israel was tested on two domesticated chickpea cultivars and two wild Cicer accessions from Turkey and Israel. Using cross-inoculation experiments, we compared pathogen aggressiveness across the different
pathogen and host origin combinations. Two measures of aggressiveness were used, incubation period and relative area under
the disease progress curve. The eight tested isolates infected all of the host plants, but were more aggressive on their original
hosts with one exception; Turkish domesticated isolates were less aggressive on their domesticated host in comparison to the
aggressiveness of Israeli domesticated isolates on Turkish domesticated chickpea. C. judaicum plants were highly resistant against all of the isolates from different origins except for their own isolates. Regardless
of the country of origin, the wild isolates were highly aggressive on domesticated chickpea while the domesticated isolates
were less aggressive on the wild hosts compared with the wild isolates. These results suggest that the aggressiveness pattern
of D. rabiei on different hosts could have been shaped by adaptation to the distinct ecological niches of wild vs. domesticated chickpea. 相似文献

We evaluated mid- to long-term outcomes with respect to function and complications in dogs undergoing canine unicompartmental elbow (CUE) arthroplasty for treatment of medial compartment disease of the elbow. This prospective multicenter case series is the first group of clinical cases to receive CUE arthroplasty. Cases (each elbow that underwent CUE performed by a participating surgeon) were enrolled into an electronic database and prospectively followed to determine and record all associated complications, as well as functional outcomes. There were 103 cases from 18 surgeons. Final follow-up time ranged from 6 to 47 mo with a mean and median of 10 mo. Canine unicompartmental elbow was associated with 1 catastrophic (1%), 11 major (10.7%), and 28 minor (27.2%) complications. Outcomes following CUE were reported as full function in 49 cases (47.6%), acceptable function in 45 cases (43.7%), and unacceptable function in 9 cases (8.7%). We conclude that CUE arthroplasty is an appropriate consideration for treatment of medial compartment disease of the elbow in dogs. 相似文献

不同耕作方式对宁南旱地土壤团聚体的影响 总被引:5,自引:0,他引:5
在宁南旱区对试验耕地定位实行连年传统翻耕(CT)、隔年免耕—深松(NT→ST)及深松—免耕(ST→NT)三种不同处理。用干筛法和湿筛法对连续3年处理后土壤团聚体的变化进行测定,分析结果表明,干筛法中NT→ST处理在0~40 cm土层中0.25 mm的机械稳定性团聚体比处理前和CT处理分别高33.11%、29.51%;ST→NT处理在0~40 cm土层中0.25 mm机械稳定性团聚体含量比处理前和CT处理分别高40.51%、36.91%。湿筛法中NT→ST处理在0~30 cm土层中0.25 mm的水稳性团聚体含量比处理前高7.33%,NT→ST处理在0~10 cm土层0.25 mm的水稳性团聚体比CT处理高1.47%,而在10~40 cm土层NT→ST处理和CT0.25 mm的水稳性团聚体含量差异不显著;ST→NT处理在0~40 cm土层中0.25 mm水稳性团聚体含量比处理前和CT处理分别高10.75%、10.12%。分析结果同时说明,采用深松—免耕(ST→NT)轮耕方式更有利于土壤团聚体含量和稳定性的增加。 相似文献
