Abstract

The cotton plant is a fiber plant that is commonly used as a raw material for textiles, beauty, and health products. To increase cotton production, the development of superior varieties using plant breeding methods in cross-analysis is necessary. The cross-analysis method is used to determine the agronomic traits that affect cotton production, by selecting yield through several other characteristics related to yield. The aim of this study was to identify which agronomic characters can be used as selection criteria to increase cotton production using cross-analysis. The research was conducted at Politeknik Negeri Jember, and included 12 independent variables and one response variable, namely cotton production. The method used in this study was to perform correlation analysis, cross-analysis, calculate direct and residual contributions, and select agronomic characters that can be used as selection criteria. The results showed that the number of fruit characters had the highest correlation with cotton production (RX9Y = 0.835). Cross-analysis was carried out, and the highest direct effect was found between the number of fruit characters and cotton production (PX9Y = 0.971). The highest direct contribution was found in the character of the number of fruit, which had a total contribution of 98.321% and residue of 1.679%. Therefore, the agronomic character that can be used as a direct selection criterion is the number of fruits.
棉花作物的农学特性(Gossypium sp)及其对棉花生产的影响使用交叉分析
棉花是一种纤维植物,通常用作纺织品、美容和保健品的原料。为了提高棉花产量,利用杂交分析中的植物育种方法开发优良品种是必要的。交叉分析法用于确定影响棉花生产的农艺性状,通过选择与产量相关的其他几个特性来选择产量。本研究的目的是通过交叉分析确定哪些农艺性状可以作为棉花增产的选择标准。这项研究在波兰国家理工大学进行,包括12个自变量和一个响应变量,即棉花产量。本研究采用的方法是进行相关分析、交叉分析,计算直接贡献和剩余贡献,并选择可作为选择标准的农艺性状。结果表明,果实性状数量与棉花产量的相关性最高(RX9Y=0.835)。进行了交叉分析,发现果实性状数量对棉花产量的直接影响最大(PX9Y=0.971),其总贡献率为98.321%,残留量为1.679%。因此,可作为直接选择标准的农艺性状是果实数量。
