Abstract

Abstract:

【Objective】To study the differences in female fertility of RN-type soybean cytoplasmic male sterile lines (A-lines) and maintainer lines (B-lines), determine whether there is a decline in female fertility in RN-type soybean cytoplasmic male sterility lines, and explore the correlation between female fertility and outcrossing rate in male sterile lines. 【Method】 Firstly, 6 pairs of sterile lines and maintainer lines were selected from more than 200 RN-type cytoplasmic male sterile lines; outcrossing rates among these lines were different. Second, the outcrossing rate of male sterile lines was evaluated using honeybee pollination in net cages. Third, six male sterile lines were pollinated by non-removing stamen test, with male parents of the same restorer line, to determine whether there were differences in fertilization and podding. Finally, the differences in survival rate between sterile lines and maintainer lines were studied by removing stamens and non-removing stamens parallel cross test with the same restorer line used as the male parent. 【Result】 The outcrossing rates in cages were significantly different among the six sterile lines tested: the highest outcrossing rate was 49.46% and the lowest outcrossing rate was 15.94%. there were significant differences among survival rates of artificial crosses of six sterile lines tested: the survival rate of sterile lines with a high outcrossing rate were significantly higher than that of medium and low outcrossing rate sterile lines and the survival rate of sterile lines with medium outcrossing rate were significantly higher than that of low outcrossing rate sterile lines. For crossing survival rate after artificially removing stamens, A-lines with high and medium outcrossing rates were significantly higher than that with low outcrossing rates; there were no significant differences among B-lines with high, medium, or low outcrossing rates; there were no significant differences among high A-lines, middle A-lines, and their corresponding B-lines, while A-lines with a low outcrossing rate were significantly lower than their corresponding B-lines. For crossing survival rate by artificially not removing stamen, A-lines with a high outcrossing rate were significantly higher than that with medium or low outcrossing rates; there were no significant differences among B-lines with high, medium and low outcrossing rates; there were no significant differences among high A-lines, middle A-lines, and their corresponding B-lines, while A-lines with low outcrossing rate were significantly lower than their corresponding B-lines. 【Conclusion】 For RN-type cytoplasmic male-sterile lines of soybean, female fertility of A-lines with high outcrossing rates were normal and female fertility of a few A-lines with low outcrossing rates were poor, affecting their seed setting. Female fertility of B-lines with different outcrossing rates were all normal, the outcrossing rate of A-lines in cages were significantly positively correlated with their crossing survival rate following artificial stamen removal and in plants where the stamen was not removed, the outcrossing rates of A-lines in cages were not correlated with their B-lines’ crossing survival rate. All parallel crosses by removing and non-removing stamens can thus be used to evaluate female fertility of A-lines.
