Correlation and Path Analysis on Main Agronomic Characters of Garlic (Allium sativum)
摘要
Abstract
Taking 21 garlic (Allium sativum L. ) varieties (lines) for sprout use as the tested materials, through correlation analysis and path analysis, the relationships between the duration from sowing to sprout harvest and other 12 agronomic characters were studied, and these 13 agronomic characters were evaluated. The correlation analysis indicated that the correlation coefficients between the duration from sowing to sprout harvest and leaf length, leaf width, cauloid height, cauloid thickness, sprout length, sprout diameter reached extremely significant level, being 0. 54, -0.61, -0.79, -0.67, -0.76 and - 0. 69 respectively. The results of path analysis and regressive equation indicated that the leaf length and cauloid thickness had greater influences on the duration from sowing to sprout harvest, and they were the main factors affecting the harvest of garlic. Therefore, these two characters could be taken as the selection characters for breeding early - maturing garlic variety for sprout use.关键词
