“…North American germplasm plays an important role in China's corn yield potential, and their genetic contribution to Chinese corn has been increasing [5][6]. Using American maize germplasm is an effective way to improve the diversity of Chinese maize germplasm for identified and screened favorable allele donors due to its clear genealogical origin and abundant genetic variation [7]. Previous studies have shown that the growth period, the silking stage, the ear height, the plant height, and the kernel moisture concentration at the R6 stage could be used to determine a maize germplasm suitable for mechanical harvesting [8].…”

In China, there are increasing needs for greater genetic diversity of maize (Zea mays L.) germplasm and for hybrids appropriate for machine harvesting. to test and distinguish American maize inbred lines with exceptional combining ability, Four Chinese maize inbred lines (Chang7-2, Zheng 58,four-144 and four-287) were used to judge combining ability and heterosis of 16 U.S.A inbred lines by a NCII genetic mating method. The result showed: Among the American inbred lines, 6M502A,LH208,NL001,LH212Ht,PHW51,FBLA and LH181 showed excellent GCA for yield characteristics; while RS710,PHP76,FBLA,and PHJ89 showed excellent GCA for machine harvesting characteristics. In hybrid combinations, NL001×Chang7-2,LH212Ht×Chang7-2,FBLA×four-144,LH181×four-287,PHK93×four-287 had better SCA for yield characteristics; while NL001×Chang 7-2,6M502A×Chang7-2,LH212Ht×Chang7-2,LH181×four-287,PHW51×Chang7-2 were better than the check for machine harvesting characteristics. NL001×Chang7-2, 6M502A×Chang7-2,LH212Ht×Chang7-2,LH181×four-287,PHW51×Chang7-2 showed excellent total combined advantages compared to the check and potential for future utilization in Inner Mongolia corn production.

“…Cuban Flint is also called Cateto in Brazil, which combines well with Tuxpeño, but it is susceptible to viral diseases (Wang et al, 1998). Germplasms from CIMMYT include more than 200 populations, among them Pop33 which is a medium-maturity subtropical population improved by backcrossing from Pool 33 (Wang et al, 1998) and Pop45 which is a subtropical population that contains germplasm of BSSS (Iowa Stiff Stalk Synthetic), Tuxpeño, Cuban Flint, and Puerto Rico (Yong et al, 2013). Since 2000, many germplasms from CIMMYT have been introduced into China and intensively studied, which has helped broaden the Chinese maize germplasm base and improve grain yield (Chen et al, 2000a(Chen et al, , 2000bFan et al, 2005Fan et al, , 2008aFan et al, , 2008bFan et al, , 2009.…”

Combining Ability Estimation for Grain Yield of Maize Exotic Germplasm Using Testers from Three Heterotic Groups

Combining ability estimates of lines to be used in breeding are useful for maize (Zea mays L.) breeders. The objectives of this study were to (i) evaluate combining ability of 25 improved exotic germplasm using different numbers of testers (1 to 3) from Suwan1, Reid, and non‐Reid heterotic groups; (ii) study differences in combining ability estimates obtained with different number of testers from the same vs. different heterotic groups; and (iii) determine the appropriate segregating (‘S’) generation in which line selection should be done to obtain stable general combining ability (GCA) estimates of lines. The results showed that three testers (one from each of the three heterotic groups) were economically best for estimating GCA effects of lines, and if a tester from one of the three heterotic groups was missed, GCA estimates for some lines were biased when compared with GCA estimates with testers from all three heterotic groups. Second, the specific combining ability (SCA) effects of test‐crosses were quite similar regardless of whether one or two testers were used from each of the three heterotic groups. Thus, to obtain reliable SCA estimates, at least one tester would need to be used from each of the heterotic groups. Third, the SCA effects were different among crosses between different lines and testers, and to obtain stable estimates of GCA effects for a line, S4 or S5 generation should be the earliest generation in which to begin selection. However, to select lines with diverse genetic backgrounds, S3 should be the key generation for selection.

“…Analysis on Current Situation of Beijing E-Waste Recycling Network. As economically advanced city in China, Beijing's per capita amount of e-waste is much higher than the national average, and it has entered the peak of waste electrical and electronic products since 2003 [2]. Accompanied by the process of urbanization, sustainable growth of population size and upgrade of consumption structure, the amount of e-waste in Beijing increased rapidly.…”

China has been actively promoting the national “urban minerals” demonstration bases, which brings great opportunities to upgrade the e-waste recycling network. This paper analyzed two problems of Beijing e-waste recycling network: lack of fundamental data and inefficiency of resources utilization, revealing that informationization is the effective way to promote scientific management and high-efficient operation of the e-waste recycling network. The main content of informationization is to build an information management system, and its primary objective is to informationize business processes. According to requirement analysis, system functions are preliminarily designed. The information management system would improve operating efficiency of the recycling network, as well as act as a basic tool of supervision, and also provide a reference for the development of e-waste recycling network of Beijing and other cities of China.
