摘要/Abstract

摘要：

【目的】研究加工番茄早熟突变体主要农艺性状对前期产量性状的直接作用、间接作用和决定系数,为加工番茄优良早熟品种的选育提供理论依据。【方法】对4份加工番茄早熟突变体的 11个主要农艺性状进行相关性、回归及通径分析。【结果】株高、始花节位、果实横径、果实纵径、单果重和一二穗结果数的变异系数较大,分别为 18.1%、12.1 %、12.9 %、13.9%、29.1%和22.7%,其可选择性较强,易于通过育种、栽培等方式得到较大程度的提高和改善。对照组单果重与前期产量呈极显著正相关,相关系数为0.892^**;一二穗结果数与前期产量呈显著性正相关,相关系数为0.822^*;处理组单果重和一二穗结果数与前期产量均呈极显著性正相关,相关系数为0.770^**和0.958^**;单果重越大、一二穗结果数越多、前期产量越高;现蕾期、始花期越早、开花至成熟天数越短,早熟性指数越高。单果重、一二穗结果数对前期产量的直接作用为正向,且相关系数为极显著正相关,在加工番茄早熟品种选育时,应结合单果重和一二穗果数2因素直接、间接作用进行选择,其中一二穗结果数起决定性因素。【结论】在加工番茄早熟品种选育过程中,要提高早熟性指数和前期产量,考虑单果重、一二穗结果数、现蕾期、始花期、开花至成熟天数等农艺性状,着重考虑一二穗结果数和单果重等农艺性状。

Abstract:

【Objective】To determine the direct, indirect and determination coefficients of the main agronomic traits of processing tomato early-maturing mutants on early yield traits, and to provide a theoretical basis for the selection and breeding of excellent early-maturing tomato varieties. 【Methods】Correlation, regression and path analysis were performed on 11 main agronomic traits of 4 processing tomato early-maturing mutants. The larger the single fruit weight, the more the number of the first and the second ears, the higher the early yield; the earlier the budding period, the early flowering period, and the shorter the number of days from flowering to maturity, the higher the premature index. 【Results】The coefficients of variation of plant height, first flower node position, fruit transverse diameter, fruit longitudinal diameter, single fruit weight and number of the first and second ears were relatively large, which were 18.1%, 12.1%, 12.9%, 13.9%, 29.1% and 22.7%, respectively, showing that there was strong selectivity and was not difficult to be increased or improved to a large extent through breeding and cultivation. The results of correlation and variability analysis showed that the weight of a single fruit in the control group was significantly positively correlated with the previous yield, with a correlation coefficient of 0.892; the number of the first or the second ears was significantly positively correlated with the previous yield, with a correlation coefficient of 0.822; the weight of a single fruit in the treatment group, the number of the first and second ears were significantly positively correlated with the previous yield, the correlation coefficients were 0.770 and 0.958; The path analysis showed that the direct effect of single fruit weight and one and two ears results was positive on the early yield. The coefficient was a very significant positive correlation. In the selection of early maturity varieties of processing tomato, the selection should be built on the direct and indirect effects of the weight of single fruit and the number of the first and second ears. Among them, the number of the first and second ears was the decisive factor. 【Conclusion】In the process of breeding early maturity varieties of processing tomato, it is necessary to increase the early maturity index and the early yield, mainly considering the agronomic traits such as single fruit weight, number of the first and second ears, budding period, initial flowering period, and flowering to maturity days, focusing on the agronomic traits such as number of ears and fruit and weight of single fruit.
