1988～1990年在保定地区自然条件下。对145个国内外不同来源的低酚棉品种(系)的生育特性、产量表现和纤维品质进行了研究。结果表明,多数品种的熟性差异不大,从播种到吐絮135～140天的品种占91.72％。产量性状中,铃重、衣分、子指和衣指的变异度较小,而子棉和皮棉产量的变异潜力较大。纤维品质性状的变异程度较产量性状小。国内品种与国外引进品种相比,具有较早熟、衣分高、子指小、产量高、纤维长、细度好的特点,而国外品种的棉铃大、纤维强度高。通过鉴定和筛选,获得了数十份具有丰产、大铃、高衣分、长纤维、高强度和细度好等不同种质特性的优异种质资源。 1988 ~ 1990 in Baoding area under natural conditions. The growth characteristics, yield performance and fiber quality of 145 low-phenolic cotton varieties from different sources at home and abroad were studied. The results showed that there was no significant difference in the maturity of most varieties, which accounted for 91.72% of the varieties from 135 to 140 days after seeding. Among the yield traits, the variation of boll weight, lint percentage, sub-index and index finger was smaller, while the variation potential of lint cotton and lint yield was larger. The degree of variation of fiber quality traits was smaller than that of yield traits. Compared with imported varieties, domestic varieties have the characteristics of earlier ripening, high apparel points, small sub-fingers, high yield, long fiber length and good fineness, while the bolls of foreign varieties are large with high fiber strength. Through the identification and screening, we obtained dozens of excellent germplasm resources with different germplasm characteristics such as high yield, big bell, high coat, long fiber, high strength and fineness.
