摘要:

为了解‘冈0996’产量潜力,确定产量与其构成因素关系,确定影响高产栽培的主要因素。以2016、2017年长江流域中熟组棉花区试和2018年长江流域中熟组生产试验中数据为基础,利用变异系数法、高稳系数法、相关性分析及通径分析等对‘冈0996’稳产性、丰产性、产量及其构成因素进行分析。结果表明,‘冈0996’产量综合表现好,稳产性、丰产性好,具有高产的潜力。‘冈0996’增产点率高达91.50%,表现出较好的环境适应性。相关性分析和通径分析结果表明铃数较其他产量构成因素对皮棉产量产生直接效应最大,且通过其他产量构成因素对皮棉产量产生间接效应值最大。‘冈0996’具有强的稳产性,丰产性好、适应性强特点,在生产中要统筹好铃数与密度之间的矛盾,合理的种植密度,力争保证单株铃数,稳定单铃质量,确保衣分是实现高产的主攻途径。

Abstract:

The objectives of this study are to understand the yield potential of ‘Gang 0996’, determine the relationship between yield and its components, and clarify main factors affecting the high-yield cultivation of the cultivar. Based on the data from the regional experiment of medium-ripe cotton group in 2016 and 2017 and the production experiment of medium-ripe cotton group in 2018 of the Yangtze River Basin, the variation coefficient, high stability coefficient, correlation analysis and path analysis were used to analyze the yield stability, yield potential, and yield and its components of ‘Gang 0996’. The results showed that ‘Gang 0996’ had good comprehensive yield performance, high yield stability and great yield potential. In the regional test, the increase point rate of ‘Gang 0996’ was as high as 91.50%, and ‘Gang 0996’ showed better environmental adaptability than other cultivars. The results of correlation analysis and path analysis showed that boll number had the largest direct effect on lint yield, and constituted the largest indirect effect through other yield components. According to the yield performance of ‘Gang 0996’, in its cultivation, the contradiction between boll number and planting density should be coordinated. Reasonable planting density, enough number of bolls per plant, stable single boll quality, and proper lint percentage are the main ways to achieve high yield.
