摘要
1998～2005年,在鲁甸县利用"七五"、"八五"南北核桃2大种群杂交育种评选出的云新高原、云新云林、云新90301、云新90303、云新90306号5个核桃杂交新品种进行试验,经过对7 a生树的生长、物候特性、抗寒性能、结果习性以及坚果品质的分析评价,综合性状表现较好,其树体矮化,具有早实、丰产、优质、耐寒的优良性能,在某些特性上又有各自的优点。可初步确定为适于鲁甸县相同条件下核桃生产的优良杂交品种。
Cultivation experiment of five walnut hybrids named Yunxin gaoyuan＇,Yunxin yunlin＇,Yunxin 90301＇,Yunxin 90303＇ and Yunxin 90306＇ were conducted in Ludian County of Yunnan Province from 1998 to 2005.Through observation on growth,phenology,cold resistance,fruiting and nut quality for seven years,these five hybrids were appraised to have promising comprehensive performance,moreover,the trees were dwarfed,and with good quality of early-fruiting,high yield and cold resistance.Based on the experimental results,these hybrids were preliminarily defined as good hybrids for Ludian County.
