本文总结了我国育成早熟品种的亲本有 CP49/50、F108、崖城红皮、CP28/11、CP34/120,N:Co310、POJ3016、Co997、Co281、CP29/320、CP34/120。育成品种最多的是极为早熟高糖的 CP49/50。自育优良早熟高糖亲本有粤糖59/65、华南56/21、粤糖59/624、粤糖62/79,育成品种最多的是粤糖59/65。 本文提出对甘蔗早熟高糖亲本应具备的条件,并根据这些条件的要求,选育了一批早熟高糖亲本,比较突出的有崖城79/277、卡1和特1,这3个亲本12月的蔗糖分分别为18:850 % 、17.652%和7.674%:它们大茎、生势强、不感染黑穗病。在选育过程中有9个品系经过一系列的选种程序试验,它们不仅具备了早熟高糖亲本的条件,而且达到早熟优良品种的要求(11月蔗糖分在13呱以上,产量不低于F134).它们正在分期分批参加海南区试品比。已有2个(崖城77/109崖城77/ 11的经过两年试验.结果,表现很好,正在进行表证和加速繁殖。
This paper summarizes the parents of cultivars of early maturing varieties in China are CP49 / 50, F108, Yacheng red skin, CP28 / 11, CP34 / 120, N: Co310, POJ3016, Co997, Co281, CP29 / 320 and CP34 / 120. The most cultivated varieties are extremely precocious high-sugar CP49 / 50. Good self-prizing high-sugar parents of the original sugar 59/65, 56/21 South China, Guangdong sugar 59/624, Guangdong sugar 62/79, the most widely cultivated varieties of Guangdong sugar 59/65. In this paper, the conditions for the early sugar cane parents should be established. According to the requirements of these conditions, a number of early-maturing high-sugar parents were bred. Among them, Yacheng 79/277, Card 1 and Special 1, the three parents The cane sugar content in December was 18: 850%, 17.652% and 7.674%, respectively: they were bulky and had strong growth potential without smut. In the breeding process, 9 strains have been tested by a series of selection programs. They not only have the conditions of early maturity high sugar parents, but also achieve the requirements of good early maturing varieties (in November, the yield of sucrose is above 13g, and the yield is not less than F134) They are participating in stages in batches than in Hainan. There have been two (Yacheng 77/109 Yacheng 77/11 after two years of the test results, performed well, are undergoing card and accelerated reproduction.
