Sugarcane ( spp., hybrids (2 n=100–130)) is one of the industrial crops cultivated mainly for sugar in the tropical and subtropical regions. It has earned the attention of many countries as a prominent energy crop owing to its exceptional biomass production potential. Energy cane is a hybrid of commercial and wild sugarcane, which was bred for high fiber content and low sucrose. Average energy cane biomass production potential is much higher, and brix levels are lower, compared with commercial sugarcane. A total of 138 spp. hybrids representing 99 interspecific hybrids (ISH) and 39 intergeneric hybrids (IGH) derived from intercrossing of species clones of , and wild genus, were evaluated along with the commercial hybrids for their cane growth and quality parameters, fibre and biomass traits. In general, the ISH and IGH clones recorded higher fibre per cent with maximum of 32% (ISH-562) and maximum biomass yield of 396.16 t/ha (ISH-571), lower values for quality characters such as juice brix 10.68% (ISH-571), sucrose 6.65% (ISH-579) and commercial cane sugar (CCS) 3.66% (ISH-579). Total biomass showed a significant positive correlation with the number of tillers (‘000/ha) at 120 days (r =0.176), number of shoots (‘000/ha) at 240 days (r = 0.129), number of stalks (‘000/ha) at 360 days (r = 0.249), cane height (r = 0.163) and single cane weight (SCW) (r = 0.508) and positive correlation with quality traits indicates the possibility of simultaneous improvement for biomass and quality traits. However, the fibre per cent has showed a significant negative correlation with quality traits ., extraction % (r = −0.616), juice brix % (r = −0.419), sucrose % (r = −0.422), CCS % (r = −0.409), cane diameter (r = −0.600) and SCW (r = −0.475) suggests difficulty in combining both the traits. In the cluster analysis, the cluster III with 12 clones is more similar to commercial cultivars for juice quality (20.16% juice brix and 18.08% of sucrose) and cane traits, however the cluster V consist of 4 clones (ISH-557, ISH-563, ISH-571 and ISH-572) recorded highest total biomass yield of 368.72 t/ha and a mean fibre of 19.50% could be exploited for green energy purposeor as parental stocks in breeding programme.

破译源自甘蔗和花茅属早期杂交种的种间和属间杂交种的生物量贡献性状。作为生物质和生物能源的潜在来源

甘蔗（spp.，杂交种（2 n=100–130））是热带和亚热带地区主要种植糖料的经济作物之一。由于其非凡的生物质生产潜力，它作为一种重要的能源作物赢得了许多国家的关注。能源甘蔗是商业甘蔗和野生甘蔗的杂交品种，是为了高纤维含量和低蔗糖而培育的。与商业甘蔗相比，能源甘蔗的平均生物质生产潜力要高得多，而白利糖度水平要低得多。共有138种。对代表 99 个种间杂种 (ISH) 和 39 个属间杂种 (IGH) 的杂种进行了评估，这些杂种源自 和野生属的物种克隆的杂交，并与商业杂种一起评估了甘蔗生长和质量参数、纤维和生物量性状。一般来说，ISH 和 IGH 克隆的纤维百分比较高，最高可达 32% (ISH-562)，最大生物量产量为 396.16 吨/公顷 (ISH-571)，果汁糖度等品质特征值较低，为 10.68%（ ISH-571)、蔗糖 6.65% (ISH-579) 和商业蔗糖 (CCS) 3.66% (ISH-579)。总生物量与 120 天时的分蘖数 ('000/ha) (r = 0.176)、240 天时的芽数 ('000/ha) (r = 0.129)、茎数 (') 呈显着正相关。 000/公顷）在360天（r = 0.249），甘蔗高度（r = 0.163）和单甘蔗重量（SCW）（r = 0.508）与品质性状呈正相关，表明生物量和品质性状同时改善的可能性。然而，纤维百分比与质量性状呈显着负相关。提取率％（r = -0.616），果汁糖度％（r = -0.419），蔗糖％（r = -0.422），CCS％（r = −0.409）、甘蔗直径（r = −0.600）和 SCW（r = −0.475）表明将这两个性状结合起来很困难。在聚类分析中，具有 12 个克隆的簇 III 在果汁品质（20.16% 果汁糖度和 18.08% 蔗糖）和甘蔗性状方面与商业品种更相似，但簇 V 由 4 个克隆组成（ISH-557、ISH- 563、ISH-571 和 ISH-572）记录的最高总生物量产量为 368.72 吨/公顷，平均纤维含量为 19.50%，可用于绿色能源目的或作为育种计划中的亲本种群。
