小海子垦区早中熟陆地棉28个品种比较

Comparison of 28 Varieties of Early-Mature Upland Cotton in Xiaohaizi Reclamation Area

通过田间试验,鉴定28个新品种(系)在小海子垦区的生育期、农艺性状、产量性状和品质性状,客观评价各品种(系)特性与生产利用价值。试验结果表明,SDS-6生育期129天,株高61.6 cm,单铃重6.1 g,衣分42.6%,籽棉产量6209 kg/hm^(2),绒长30.0 mm,比强度31.3 cN/tex,马克隆值4.8;SDS-5生育期128天,株高74.3 cm,单铃重5.1 g,衣分41.5%,籽棉产量5777 kg/hm^(2),绒长30.8 mm,比强度30.9 cN/tex,马克隆值3.9;棉城17生育期129天,株高64.6 cm,单铃重5.9 g,衣分42.4%,籽棉产量5919 kg/hm^(2),绒长33.5 mm,比强度31.4 cN/tex,马克隆值4.6。SDS-6、SDS-5和棉城17均可作为小海子垦区生产上的品种。

Through field experiments,the growth period,agronomic traits,yield traits and quality traits of new varieties(lines)in Xiaohaizi Reclamation Area were identified,and the characteristics and production and utilization values of each variety(line)were objectively evaluated.The results showed that the growth period of SDS-6 was 129 days,the plant height was 61.6 cm,the single boll weight was 6.1 g,the lint was 42.6%,the seed cotton yield was 6209 kg/hm^(2),the pile length was 30.0 mm,the strength is 31.3 cN/tex,and the micronaire value was 4.8;the growth period of SDS-5 was 128 days,the plant height was 74.3 cm,the single boll weight was 5.1 g,the lint was 41.5%,the seed cotton yield was 5777 kg/hm^(2),the pile length was 30.8 mm,the strength was 30.9 cN/tex,and the micronaire value was 3.9;the growth period of Miancheng 17 was 129 days,the plant height was 64.6 cm,the single boll weight was 5.9 g,the lint is 42.4%,the seed cotton yield was 5919 kg/hm^(2),the pile length was 33.5 mm long,the strength was 31.4 cN/tex,and the micronaire value was 4.6.SDS-6,SDS-5,and Miancheng 17 can be used as materials for the selection of production varieties in this region.
