Changes of Photosynthetic Characters and Canopy Agronomic Traits among Different Maturity Groups in Soybean Genetic Improvement
摘要
Abstract
Fifty-seven soybean cultivars released from 1923 to 2008 in Jilin province were divided into three soybean maturity groups(medium-early,medium and medium-fate) ,and evaluated the genetic improvement of soybean agronomic characters in different canopy and some leaf photosynthetic characteristics,as well as the correlation between these characters and yield. For different maturity soybeans, yield, 100-seed weight, plant height, leaf area per plant, petiole length, photosynthetic rate and SPAD value at R5 were positively correlated with released years, while numbers of branches was negatively correlated with released years;pod number,pod weight(P <0. 05) ,seed number and stem weight per plant were positively correlated with yield. As a whole,medium-early and medium-late maturity groups had the same evolution lendency,in which 100-seed weight,plant height, seed number per plant, leaf area per plant, petiole length, photosynthetic rate and. SPAD value at R5 were positively correlated with yields and released years,respectively;among all characters,SPAD value at R5 was the steadiest, and positively correlated with yield and released years respectively in each maturity group.关键词
