The Evolutionary Trend of Important Traits of the Tibetan Hulless Barley Core Parent Kunlun 1 and its Derivatives
摘要
Abstract
Hulless barley is an important cereal crop worldwide,especially in Tibet of China.Here we compared important agronomic traits of the Tibetan hulless barley core parent Kunlun 1 and its derivatives.Relative to Kunlun 1,three derived varieties showed an in-crease in plant height (by 8.17%,18.77%,and 14.74% respectively;but reductions in leaf length,leaf width,and flag -leaf size, whose compact leaf shape favors high yielding.Moreover,the derived varieties were significantly greater than Kunlun 1 in spike length, effective spike number per plant,grain quality,and yield of unit area.But there were no notable differences in spike number between Kunlun 1 and its derivatives.Besides,the derived varieties had slightly lower 1000 -kernel weight than Kunlun 1.According to the correlation analysis of the derived varieties,their yield was positively correlated with their spike weight and effective spike number of per plant to a significant degree;but negatively correlated with their effective spike number,spike length,and plant height to a signifi-cant extent,whereas their yield had no close relationship with their spike number and weight.The derived varieties inherited the high-yielding traits of Kunlun 1 such as bigger spike and higher 1000 -kernel weight.关键词
