不同大豆品种(系)低钾耐性的差异
Difference of Tolerance to Low Potassium in Soybean Varieties (Lines)
摘要
Abstract
For the servere actuality of potassium resources deficiency in China, seventy-two soybean varieties (lines) from three northeast provinces were used in the field experiment with low potassium stress and adequate potassium supply. Difference of tolerance to low potassium was evaluated by yield from 2006 to 2008. The objectives were to explain the mechanism and genentic characters of tolerance to low potassium, and to supply the reference for breeding in soybean. The results showed that genotypic difference of yield and relative yield of soybean varieties (lines) were significant. Most of soybean varieties (lines) showed the medium adaptability, whereas some varieties (lines) were tolerance or sensitive to potassium deficiency. According to relative yield, these soybean varieties (lines) were divided into three types: (1) Relative yield more than 0.90 was tolerance to low potassium, such as 94001, T40, Tiefeng 33, Fuhei 1 and Jiunong 20. (2) Relative yield of 0.70-0.90 was moderate to low potassium, such as Xin 8, Tiefeng 31, Tie 96027, Dandou 11, Qingpidou and GD3264. (3)Relative yield less than 0.70 was sensitive to low potassium, such as GD1575, GD8521, shi 2.GD2910 and 94133.关键词
