不同育成年代大豆品种光合速率及农艺性状分析 总被引:2,自引:0,他引:2
为筛选出具有高光效和农艺性状优良的大豆种质资源,对黑龙江省和吉林省育成的140份大豆品种进行了光合速率和农艺性状的变化分析。结果表明:随着年代的推移,不同年代品种在始荚期(R3)、始粒期(R5)、鼓粒期(R6)3个时期光合速率平均值呈递增趋势;各熟期组间光合速率的平均值差异不显著,但熟期组内变异系数较大,说明可以从不同熟期组中筛选光合速率高的材料作为高光效、高产优异的品种资源利用,例如:黑河27、黑河38和黑农41等品种;生育日数有缩短趋势;株高和主茎节数有增加趋势;单株荚数、单株粒重和百粒重随年代递增,是产量随年代增加的主要因素。 相似文献

QTL Analysis of Major Agronomic Traits in Soybean 总被引:4,自引:0,他引:4
CHEN Qing-shan ZHANG Zhong-chen LIU Chun-yan XIN Da-wei QIU Hong-mei SHAN Da-peng SHAN Cai-yun HU Guo-hua 《中国农业科学(英文版)》2007,6(4):399-405
Soybean is a main crop, and most agronomic traits of soybean are quantitative; therefore, there is vely important studying and applying value to locating these traits. A F2:10 RIL population containing 154 lines, derived from the cross between Charleston as female and Dongnong 594 as male parent, were used in this experiment. A genetic linkage map was constructed with 164 SSR primers, which were screened with the two parents and amplified on the 154 lines. 12 agronomic traits different between the two parents were investigated, and QTLs of all the traits were analyzed using the software Windows QTL Cartographer V2.0. The agronomic traits included quality traits: protein content, oil content, and content of protein and oil; yield traits: pods per plant, seed weight per plant, and 100 seeds weight; and other agronomic traits: plant height, days to maturity, branches, nod number in main stem, average leaf length, and average leaf width. The results showed that 68 QTLs in total were found for the 12 agronomic traits. The number of QTLs per trait varied from 3 for the average leaf width to 11 for 100 seeds weight and plant height, and was 5.8 on average. Good accordance was seen in many QTLs between the results of this study and the results obtained by other similar studies; therefore, these QTLs may be valuable for molecular marker assistant selection in soybean. In this study, 68 major QTLs of 12 important traits of soybean were analyzed. 相似文献

Effect of Preplant Fertilizer on Agronomic and Physiological Traits of Soybean Cultivars from Different Breeding Programs 总被引:1,自引:0,他引:1
Understanding the changes in agronomic and physiological traits associated with yield genetic gain is important for soybean production and future breeding strategy. The objective of this study was to compare the older and modern cultivars to learn whether the yield improvements depend on preplant fertilizer or the plant productivity improvement, A set of older cultivars, with their modern counterparts derived from breeding programs in Liaoning and Ohio were evaluated for their agronomic and physiological traits under different fertilizer levels from 2004 to 2006. There was no improvement of response to N and P preplant fertilizer for genotypes. After more than 70 yr breeding, soybean breeders made some improvements in agronomic and physiological traits that contribute to yield increase. When compared to older cultivar, modern Liaoning and Ohio cultivars were shorter and more resistance to lodging, had greater leaf density, higher harvest index, more leaf area per plant, and greater photosynthetic rate, transpiration rate and stomatal conductance at the beginning of seed development. Ohio cultivars were more resistant to lodging as if selected for easy harvest by combine, even under high N and P preplant fertilizer level, which resulted in Ohio cultivars with higher and stable yield productivity. 相似文献
