Research on oil fruit evaluation of Camellia chekiangoleosa Hu Germplasm
摘要
Abstract
For breeding and popularization of Camellia chekiangoleosa Hu,and to screen the clones with high oil fruits,this paper investigated 10 clones of C.chekiangoleosa(numbered as H1-H10)planted in the oil tea germ-plasm base of Forestry Science and Technology Extension Centre of Hubei Province.The 13 traits of mature fruits were tested and analyzed,followed by comprehensive ranking using principal component analysis.Results included the following parts.Fruit color of H5 and H8 were cyan-red,H3 was red,and the rest were red-cyan.Fruit shape in-dex was from 0.84 to 1.06,the fruit shape of H3,H8 and H10 were orange-shaped,the rest were spherical.Fresh fruit's transverse diameter was from 44.05 to 54.65 mm,their longitudinal diameters were from 38.21 to 53.56 mm.Fresh weight of single fruit was from 24.37 to 38.26 g.Moisture content of fresh fruit was from 41.64%to 52.15%,with seed rate of fresh fruit from 35.91%to 61.71%,kernel rate of dry seed from 48.00%to 63.94%,dry kernel oil content from 38.10%to 51.00%,fresh fruit oil content from 5.02%to 7.82%,and unsaturated fatty acid content from 87.51%to 89.16%.Four principal components with eigenvalue more than 1 were extracted,and the cumulative contribution rate was 86.222%.Comprehensive evaluation based on principal component analysis showed the rank of fruit oil value from high to low was:H8>H3>H4>H5>H9>H10>H1>H2>H7>H6.Clones H8,H3 and H4 showed the best overall performance and might be used as candidate germplasm for further breeding.关键词
