Abstract

This study was carried out to estimate the broad-sense heritability for seed yield and some yield components of safflower (Carthamus tinctorius L.) cultivars. The experimental design was a randomized complete block design with three replications in the 2004 growing season in the Middle Black Sea Region conditions of Turkey. Three safflower cultivars (5-154, Dinçer and Yenice) were grown at five locations (Bafra, Ladik, Suluova, Gümüşhaciköy and Osmancik). The heritability for seed yield, plant height, first branch height, number of branch, head diameter, number of seed per head, 1000-seed weight and oil content were estimates as 35%, 93%, 99%, 45%, 21%, 69%, 81% and 59%, respectively. It was found that first branch height was the least affected trait over environments and followed plant height, thousand seed weight and number of seed per head. On the other hand, head diameter, seed yield, number of branch and oil content were the most affected traits versus environmental conditions. The first branch height, plant height and 1000-seed weight could be used to succeed in selection in early generation.

摘要

本研究旨在估算红花（Carthamus tinctorius L.）品种种子产量及一些产量构成因素的广义遗传力。试验设计为随机完全区组设计，于2004年生长季在土耳其中黑海地区条件下进行了三次重复。三个红花品种（5-154、Dinçer和Yenice）在五个地点（巴夫拉、拉迪克、苏洛瓦、居穆什哈吉克öy和奥斯曼奇克）种植。种子产量、株高、第一分枝高度、分枝数、头状花序直径、每头状花序种子数、千粒重和含油率的遗传力估计分别为35%、93%、99%、45%、21%、69%、81%和59%。结果发现，第一分枝高度是受环境影响最小的性状，其次是株高、千粒重和每头状花序种子数。另一方面，头状花序直径、种子产量、分枝数和含油率是受环境条件影响最大的性状。第一分枝高度、株高和千粒重可用于早期世代的成功选择。
