Abstract

The objective of this work was to select black oat genotypes using the MGIDI for simultaneous selection, comparing it with the Smith-Hazel index. The experiment was carried out in Frederico Westphalen/RS and Pato Branco/PR, in a randomized block design, with three replications, with 9 genotypes tested. Days from emergence to flowering and maturation; cutting and plant height; number of tillers; panicle length; tiller, plant, panicle, panicle seed mass, green and dry; and seed yield were obtained. MGIDI selected the genotypes UFSMFW 2-01 and UFSMFW 2-04 for Frederico Westphalen and UFSMFW 2-07 and UFSMFW 2-04 for Pato Branco, which varied compared to the Smith-Hazel index in both environments. MGIDI was efficient in selecting the best black oat genotypes, showing desirable selection gains for most traits.

利用MGIDI指数选育优质黑燕麦品系

本工作的目的是利用MGIDI进行同时选择，并将其与Smith-Hazel指数进行比较。试验采用随机区组设计，3个重复，共检测9个基因型。从萌芽到开花和成熟的天数;切割和株高;分蘖数;圆锥花序长度;分蘖，植株，圆锥花序，圆锥花序种子块，绿色和干燥;得到了种子产量。MGIDI为Frederico Westphalen选择了UFSMFW 2-01和UFSMFW 2-04基因型，为Pato Branco选择了UFSMFW 2-07和UFSMFW 2-04基因型，与两种环境下的Smith-Hazel指数相比有所不同。MGIDI在选择最佳黑燕麦基因型方面是有效的，在大多数性状上表现出理想的选择增益。
