Analysis of Growth and Development Characteristics and Lodging Resistance of Different Foxtail Millet Cultivars(Strains)
摘要
Abstract
In order to reveal the growth and development characteristics and lodging resistance of 42 foxtail millet cultivars(strains) from Henan,Hebei and Shandong provinces,totally 15 traits including days to heading, plant height, panicle length, ear diameter ( represented by ear circumference ) , grain weight per spike,panicle type,lodging index of the first node and so on were identified systematically. The results showed that among the 42 foxtail millet cultivars( strains) ,days to heading ranged from 33 d to 60 d, the shortest days to heading was Longgu 26 ( 33 d ) , followed by 8322-14 ( 36 d ) , the longest days to heading was Jigu 15,K325 and Jigu 29(60 d). Plant height ranged from 43. 72 cm to 81. 19 cm,the lowest was Jigu 28 ( 43 . 72 cm ) , the highest was An 04-4705 ( 81 . 19 cm ) . Panicle length ranged from 7. 71 cm to 16. 33 cm,the shortest was Jigu 28(7. 71 cm),the longest was An 04-5014(16. 33 cm). Ear diameter ranged from 3. 85 cm to 6. 18 cm,the thickest was Jigu 15(6. 18 cm),the finest was Jigu 27 (3. 85 cm). Lodging index ranged from 0. 18 to 0. 82,the strongest was Jigu 22(0. 18),the weakest was 200152. Comprehensively,Yugu 15 and Zheng 05-1 from Henan province,104 and 06-766 from other regions gave better performance with longer panicle,thicker ear,and stronger lodging resistance. Jigu 27 and Longgu 26 gave poorer performance with smaller panicle and weaker lodging resistance.关键词
