Abstract

Field experiment was conducted during 2017-18 at Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study the effect of row spacing on yield and quality of early maturing sugarcane genotypes. Treatment included two row spacing (90 and 120 cm) and five genotypes viz., ‘CoLk 12207’, ‘CoP 12436’, ‘CoSe 12451’, ‘BO 130’ and ‘CoSe 95422’. Significantly higher plant population, leaf area index (4.18), dry matter accumulation (34.8 t/ ha) and millable canes (126, 200/ ha) were recorded with 90 cm row spacing gave significantly highest cane (96.2 t/ ha) and sugar yield (11.6 t/ ha). Results showed that genotype CoSe 95422 superseded other genotypes in growth and yield attributing characters. Maximum cane yield (104.4 t/ ha) was noticed due to the genotypes CoSe 95422. However, maximum brix (20.3%), pol (18.13%) and CCS percent (12.60%) were noted with the genotype CoLk 12207 which was statistically similar to BO 130. Significantly higher sugar yield (12.4 t/ha) was obtained with the genotype CoSe 95422 which was statistically comparable to CoLk 12207 and CoSe 12451.

甘蔗(Saccharum spp. hybrid complex)早期新基因型的行距影响

2017- 2018年，在比哈尔邦萨玛斯提普尔普萨的Rajendra Prasad博士中央农业大学甘蔗研究所进行了田间试验，研究了行距对早熟甘蔗基因型产量和品质的影响。处理为2个行距(90和120 cm)， 5个基因型(CoLk 12207、CoP 12436、CoSe 12451、bo130和CoSe 95422)。行距为90 cm时植株数量、叶面积指数(4.18)、干物质积累量(34.8 t/ ha)和甘蔗产量(12.26 200 t/ ha)显著增加，甘蔗产量(96.2 t/ ha)和糖产量(11.6 t/ ha)显著增加。结果表明，CoSe 95422基因型在生长性状和产量性状上优于其他基因型。由于基因型CoSe 95422，甘蔗产量最高(104.4吨/公顷)。而CoLk 12207基因型与bo130基因型差异有统计学意义，其最高白度(20.3%)、最高检出率(18.13%)和最高检出率(12.60%)。基因型CoSe 95422的糖产量(12.4 t/ha)显著高于CoLk 12207和CoSe 12451。
