对苏鲁两省沿海地区10个产地苦楝Melia azedarach果实长、果实宽、果实长宽比、果实千粒质量、核果长、核果宽、核果长宽比和核果千粒质量8个果实性状进行测定和分析.结果表明,各性状在产地间和产地内家系间存在显著差异,产地间变异系数为2.15%~18.53%,均小于产地内家系间变异系数.产地间广义遗传力为59.68%~96.06%,亦均小于产地内家系间的广义遗传力.说明苦楝产地间和产地内家系间存在丰富的遗传变异,且产地内家系间变异>产地间变异.相关分析结果表明,供试苦楝产地果实性状受经度和纬度双重影响,主要呈现以纬度为主,以经度为辅的变异模式,聚类分析结果进一步验证了这一判断.苦楝产地内和产地间丰富的遗传变异为选育抗风耐盐等优良品种提供了资源基础.图1表4参9
對囌魯兩省沿海地區10箇產地苦楝Melia azedarach果實長、果實寬、果實長寬比、果實韆粒質量、覈果長、覈果寬、覈果長寬比和覈果韆粒質量8箇果實性狀進行測定和分析.結果錶明,各性狀在產地間和產地內傢繫間存在顯著差異,產地間變異繫數為2.15%~18.53%,均小于產地內傢繫間變異繫數.產地間廣義遺傳力為59.68%~96.06%,亦均小于產地內傢繫間的廣義遺傳力.說明苦楝產地間和產地內傢繫間存在豐富的遺傳變異,且產地內傢繫間變異>產地間變異.相關分析結果錶明,供試苦楝產地果實性狀受經度和緯度雙重影響,主要呈現以緯度為主,以經度為輔的變異模式,聚類分析結果進一步驗證瞭這一判斷.苦楝產地內和產地間豐富的遺傳變異為選育抗風耐鹽等優良品種提供瞭資源基礎.圖1錶4參9

Eight characteristics(i. e. length, width, and length. width ratio of both drupes and stones along with weight per 1 000 drupes and 1 000 stones)for ten producing areas of Melia azedarach in coastal areas of Jiangsu and Shandong Provinces were measured and analyzed using correlation and cluster analyses. Results showed that each index differed significantly between families both for all producing areas(P<0. 05)and within each area(P<0. 05). In addition, the coefficient of variation for all producing areas was 2. 1%-18. 5%which was less than between families within each producing area. The broad hefitability for all producing areas was 60. 0%-96. 1%which was also less than between families within each producing area. Correlation and cluster analyses showed that both latitude(r=0. 632)and longitude(r=0. 549)influenced fruit characteristics. Results suggested that there was abundant genetic variation between families for all producing areas as well as within each area. [Ch, 1 fig. 4 tab. 9 ref. ]
