细长粒粳稻新品种云粳优1号选育及特性研究

云粳优1号是用细长粒型粳稻新品系银条粳作母本,高产、高抗稻瘟病、耐寒的合系34号作父本进行杂交,经过5年7代选育而成。选育过程中从集团单株选拔开始,每年都对高产性、品质、稻瘟病抗性、耐寒性进行同步鉴定,作为选拔的科学依据。与此同时,对云粳优1号的丰产性、适应性、品质特性、抗病性、耐寒性进行研究,并提出了相应的栽培措施。

Identification of Macropterous Individual of Cixiopsis punctatus(Hemiptera:Fulgoroidea:Tropiduchidae) Based on Morphological and Molecular Data

The macropterous individual of Cixiopsis punctatus Matsumura is recognized based on morphological comparison and the mitochondrial COI gene sequences.The pairwise distances among the specimens examined ranged from 0 to 0.0228.Mean distance between macropterous female（Cixiopsis sp.） and 5 brachypterous specimens of Cixiopsis punctatus is 0.0161,which was close enough to consider the macropterous female and brachypterous specimens to be the same species.The external morphology of macropterous female of Cixiopsis punctatus is firstly illustrated and described.
