摘要
较详细研究了1980年引进的运河点(CP 系)甘蔗品种作杂交亲本的利用价值,结果表明杂交后代表现早熟、高糖、丰产、宿根性好,从中选育出如粤糖83/271、83/257、83 /251等优良的甘蔗新品种。在所研究的新 CP 亲本中,CP 72/1210表现最为突出,是个优良的母本;CP 57/614是个早熟高糖遗传性特强的父本,但后代茎型不太理想且容易开花,回交利用价值较大;CP 67/412的后代早生快发,生势旺盛,植株高大,糖份、产量及宿根性较突出,但孕穗开花及空蒲心较重;另 CP 65/357、72/1312等的后代也均有良好表现。选择大茎丰产、较难开花的栽培品种与这批新 CP 亲本杂交,选育出适应于水田、旱地及有雷冻等各类型蔗区种植的早熟、高糖丰产、宿根性强的优良品种,是能够达到目的的。
The useful value as crossing parents on the new CP varieties intro- duced in 1980 were detailed studied.The results indicated that their hybrid progenies had the characteristics of early maturing,high sugar content, high yield and excellent ratooning ability.From these progenies,many good varieties,such as Yuetang 83/271,83/251,83/257,had been selected.Of the CP parental varieties studied,CP 72/1210 performs best and it can be used as good female parent;CP 57/614,a desirable male parent,easily transmits its attributes of early maturing and high sugar content to its progenies,but has undesirable stem characters and easily flowers,its breeding value will be greater by back-crossing;the progenies of CP 67/412 exhibit early,quick,vigorous growth,tall plant height,high sugar content, high yield and excellent ratooning ability,but many individuals are eared of flowering,have hollow or pithy stems;the progenies of CP 65/357 and CP 72/1312 also perform well.It is suggested that the CP parental varieties should be crossed with the thick stalk,difficult flowering cultivars,in order that the early-maturing,high sugar content,good ratooning power varieties adapted to various sugarcane districts of march field.non-irrigated land,frost area,can be developed.
