红花含油率选择方法的研究

我们选用9个栽培红花品种为试验材料,进行含油率选择方法的研究。结果表明:诸性状中,对含油率的影响以种壳率最大,其次是分枝高和株高。通过种壳率进行间接选择,可有效提高含油率。这3性状综合选择,对提高含油率的效果大于单性状相关选择的作用。采用分枝高、百粒体积、始花开花天数、种壳率4性状构成的选择指数对含油率进行选择时的效果最好。用该选择指数对9个参试品种评审结果表明,油酸李德是综合性状优良的最佳油用型品种,夫里奥和AC—1次之。UC—26和张掖无刺是综合性状最差的低含油率品种。

A STUDY OF A METHOD FOR SELECTION OF OIL-BEARING RATE IN SAFFLOWER

This experiment was carried out with nine cultivars of safflower used as materials.The results showed that hull rate had a greatest influence on oil-bearing rate among 5 characters,next were the plant height and branches.The oil-bearing rats could be raised effectively,with indirect selection of hull rate.The complexive selection of three characters mentioned above had a better effect on raising oil-bearing rate than the selection of single character.The selection index,which consisted of branch height,one-hundred-seed volume,the number of days during initial blossom and hull rate,had a best effect when they were usad for selection of oil-bearing rate.When above nine safflower cultivars were appraised with the selection index,the results showed that "Oleic Leed" was a best variety with fine complexive characters,while "UC-26" was a variety of low oil-bearing rate with the poorest complexive characters.
