河南省花生材料观察试验及主要性状相关性分析

为了筛选出适合我国北方广大花生产区种植的产量高、品质好、出油率高及适应性、抗逆性强等综合性状优良的花生品种,选出8个花生材料,以花育19为对照,通过不同试验比较,观察其生育期、抗病性、生物学性状、各品质指标及产量指标。结果表明:L15-3产量高,稳产性好,2015-2016年连续2a试验平均产量比对照品种花育19提高34.31%,居所有参试材料第一位;在8个参试花生品种中,L15-3蛋白质含量最高达到26.5%,居所有参试品种第一位,粗脂肪含量最高达到57.6%;出油率高达56.4%,属于高含油量类型。L15-3不仅高产稳产,而且品质好出油率高。随着人们生活的改善,对花生品质粗脂肪及高蛋白优质花生品种需求逐步提高,L15-3选育成功,很好解决了我国大果花生高产与品质、大果与品质呈负相关的矛盾,集大果、高产、稳产、品质好、出油率高于一身。适宜在我国北方广大花生产区推广种植。

Comparative Test and Correlation Analysis of New Peanut Varieties of Henan

In order to screening the good peanut varieties with high yeild,good quality,high oil yield,strong adaptability and resistance suitable for peanut production areas in the north of China,a comparisive trial of 8 new introduced peanut varieties was conducted under natural conditions.The results showed that the pod and grain seed yields of L15-3 was the best of all.The landraces from 8 new peanut varieties possessed medium protein contents together with relatively high oil content and oleic acid content on average.However,the protein content of L15-3 was over 26.5%,oil content was over 56.4%,and the crude fat contentst was over 57.6%.The correlation analysis on main characteristics and the single plant productivity showed that the filled pod number were very significantly correlated with the filled pod number in single plant.It solved the big fruit peanut yield and quality in our country.The contradiction between large fruit and negatively was correlated with the quality.It was big fruit,high yield and stable yield,good quality and yield efficiency higher than a suit.In a word,L15-3 was suitable for planting in northern.
