摘要/Abstract

摘要： 【目的】筛选出优良籽瓜品种(系),挖掘新疆籽瓜生产潜力。【方法】选择12个籽瓜品种(系)的生育期、经济产量共11个指标,利用主成分分析进行综合评价。【结果】参试品种中全生育期时间最长的为品系1612,平均119.33 d,生育期最短的是品系1607、1608,分别平均为112.00 d。品系1614的百粒重最高(24.53 g)。主成分分析结果表明,经济产量得分最高的是品系1614、1612;生育期因子得分最高的是品系1614;营养生长决定因子得分最高的是品系1618;综合得分最高的是品系1612,其次是品系1614。【结论】籽瓜生长发育过程中经济产量与其各个生长发育时期紧密相关,百粒重与全生育期呈显著正相关,粒数与始花期呈显著负相关;粒重与始花期呈显著负相关;参试品种(系) 1614、1612综合评价分别排名第1名、第2名,其生育期适当、经济产量优良,具有丰产潜力,可作为重点材料加以利用。

Abstract: 【Objective】 To further screen out fine seed-watermelon varieties (lines), and exploit the development potential of Xinjiang seed-watermelon.【Method】In this study, the growth period and economic yield of 12 seed-watermelon varieties (lines) were recorded by 11 indexes, and comprehensive evaluation was carried out by principal component analysis.【Result】The longest period of whole growth period was 1612, the average was 119.33 d, the shortest growth period was 1607, 1608, and the average was 112 d. The weight of the line 1614 was the highest (24.53 g). The results of principal component analysis showed that the highest score of economic output was 1614 and 1612, the highest score of growth period factor was 1614, the highest score of nutrition growth determinant was 1618, the highest score was 1612, followed by 1614.【Conclusion】The growth period is closely related to the growth and development of economic output and the seed melon, 100 grain weight and whole the growth period was positively related to the grain number and flowering period was negatively correlated with flowering; grain weight was negatively correlated; varieties (lines) 1614, 1612 comprehensive evaluation respectively ranked first and second, respectively, which proved that they can be used as a key material for its proper growth period, good economic yield and high yield potential.

Key words: seed-watermelon; growth period; economic yield; principal component analysis
