不同数学方法对板栗授粉组合的评价与筛选

Comprehensive evaluation and screening of different pollination combinations of chestnut based on different evaluation methods

以河北省迁西地区板栗主栽品种‘燕山早丰’和‘大板红’为材料,选用燕山地区8个优良品种(系)进行授粉试验,通过调查不同授粉组合产量和测定果实品质等指标,并采用直接排序法和平均隶属度法进行评价,筛选最适授粉组合。结果表明:与对照比较,采用直接排序法对产量和品质进行综合评价,‘燕山早丰’授粉组合中只有‘燕山早丰’ב迁西15号’和‘燕山早丰’ב大板红’排在对照之前,而‘大板红’授粉组合中优于对照的有‘大板红’ב迁西14号’‘大板红’ב遵玉’‘大板红’ב迁西15号’‘大板红’ב燕龙’‘大板红’ב燕山早丰’;采用平均隶属度法对产量和品质进行综合评价,‘燕山早丰’ב迁西15号’‘燕山早丰’ב大板红’和‘燕山早丰’ב遵玉’排在对照之前,而‘大板红’授粉组合排名与直接排序法非常相近。综合分析认为:在迁西地区‘燕山早丰’的最适授粉亲本为‘迁西15号’和‘大板红’;‘大板红’的最适授粉亲本为‘迁西14号’‘遵玉’和‘迁西15号’。

In order to improve the yield of chestnut in Qianxi County of Hebei Province and select the optimum pollination combinations, eight excellent chestnut varieties were selected as paternal pollinators, two main varieties in Qianxi County as maternal parent. Direct sorting method and subordinate function method were employed to evaluate different pollination combinations based on the investigation of yield and fruit quality. The results indicated that only ＇ Yanshanzaofeng＇ × ＇ Qianxil5＇ and ＇ Yanshanzaofeng＇ × ＇ Dabanhong＇ ranked higher than that of control among pollination combinations with ＇ Yashanzaofeng＇ as female parent using direct sorting method. Five pollination combinations ranked higher than that of cont,＇ol among pollination combinations with ＇ Dabanhong＇ as female parent. The five pollination combinations were ＇ Dabanhong＇ × ＇ Qianxil4＇, ＇ Dabanhong＇ × ＇ Zunyu＇, ＇ Dabanhoug＇ × ＇ Qianxil5＇, ＇ Dabanhong＇ × ＇ Yanlong＇ and ＇ Dabanhong＇ × ＇ Yanshanzaofeng＇ , respectively. Using subordinate function method, ＇ Yanshanzaofeng ＇ ×＇ Qianxil5 ＇ × ＇ Yanshanzaofeng ＇ x ＇ Dabanhong ＇ and ＇ Yanshanzaofeng＇× ＇ Zunyu＇ all ranked higher than that of control among pollination combinations with ＇ Yashanzaofeng＇ as female parent. The ranking of pollination combinations with ＇ Dabanhong＇ as female parent was similar to that of using direct sorting method. Through comprehensive analysis, we can conclude that ＇ Qianxil5 ＇ and ＇ Dabanhong＇ , are the best pollination varieties for ＇ Yanshanzaofeng＇. ＇Qianxil4＇ , ＇Zunyu＇ and ＇Qianxil5＇ are the optimum pollination varieties for ＇Dabanhong＇.
