A new sugarcane clone AEC86-347, was obtained from seed (fuzz), of a cross combination of NCo 310 x CP57-614, imported from ARS, USDA, Canal Point, Florida, USA. The genotype was evaluated for the stability of its performance for economic characters at six different locations in the Province of Sindh for the two consecutive years. Significant (P≤0.01) differences were observed in genotypes and locations x genotypes interactions for the three traits i.e., cane yield, commercial cane sugar and sugar yield. This phenomenon indicates the presence of genetic variability amongst the genotypes and their differential response to varying environments. High mean performance of AEC86-347 with 'b' values more than 1.00 for cane yield, sugar yield and CCS (%) indicated its potential to take advantage of favourable environmental conditions for yield under different locations.
ADAPTATION OF DIFFERENT SUGARCANE CLONES OF PHILIPPINE IN SEMI-ARID CONDITIONS OF PUNJAB, PAKISTAN
Present study was conducted at Surgarcane Research Institute, Faisalabad, Pakistan during 2018-19 to evaluate twelve (12) exotic sugarcane clones imported from Philippines for biometric traits and diseases resistance in local climatic conditions. These clones were put in preliminary yield trials (4 th stage) of varietal development program to evaluate their performance in comparison with local check varieties HSF 240 and CPF 249. The exotic genotypes along with local checks were subjected to randomized complete block design (RCBD) by keeping three replications during crop season 2018-19. Six biometric traits like germination%, tillers per plant, no. of canes, cane weight, cane yield and sugar contents along with resistance to two major diseases viz. red rot and smut of sugarcane were studied. Two-sided Dunnett's multiple test was used for comprehensive comparison among bimetric traits. The results of this study indicated that all the clones differed significantly for their agronomic traits. Although some varieties of Philippines showed better performance for cane yield (PSR 01-46, 184.7 t/ha) as compared to check varieties but they could not surpass them for sugar contents (11.54%) and also found susceptible to red rot and smut diseases. Only three exotic clones viz. PSR 01-28, PSR 98-11 and PSR 99-182 were promoted to next selection stage of varietal development program on the basis of higher or comparable cane yield (120.7, 141.7 and 105.3 t/ha, respectively) than check varieties and diseases reaction. However, the sugar contents of these exotic clones were found at par with check varieties and thus further testing and evaluation is required to improve adaptability and stability for consistent performance under local agro-ecological conditions.

Sugarcane is a main cash crop of Pakistan grown extensively in varying agro-climatic conditions. It confers a sound economic base to the sugar industry and also supports paper and chipboard manufacturing industry. The rapid human population growth in the country has increased the sugar demand. The present position of low yield and recovery in sugarcane stipulates the breeders to take realistic innovative attempts in varietal development programs to evaluate and release new sugarcane of high cane and sugar yield potential to fulfill the sugar demand in the country. Limited work regarding appraisal of variation in lately evolved sugarcane genotypes for morphological and quality-related characters has been reported in Pakistan. Evaluation of sugarcane genotypes for desired attributes acceptable to growers and sugar mills is necessary before releasing them as commercial varieties. The study was undertaken to evaluate variations in sugarcane genotypes employing four morphological (Cane thickness, cane height, millable stalks, and cane yield) and four quality-related (Brix, pol, purity, and commercial cane sugar percentage) traits. Experiments were conducted in plant crop for two consecutive years 2018-19 and 2019-20 during the autumn cropping season at Makli farm of PARC-National Sugar and Tropical Horticulture Research Institute (NSTHRI), Thatta, Pakistan. A total of four sugarcane genotypes i.e., YtTh-1701, YtTh-1705, YtTh-1707, and YtTh-1730 against standard variety Thatta-10 as check were tested. The genotypes were developed from the exotic fuzz of China. The trials were conducted under RCBD with three replications. The ANOVA exhibited significant (p≤0.05) differences among the genotypes for cane thickness, cane height, number of millable canes, and cane yield, whereas, non-significant (p≥0.05) variations were observed for brix%, pol%, purity% and commercial cane sugar percentage (CCS%). The mean data showed a maximum cane yield of 150.84 t ha-1 for YtTh-1705, followed by YtTh-1707 (145.42 t ha-1) and YtTh-1701 (142.29 t ha-1). Whereas, the minimum yield of 104 t ha-1 was recorded in YtTh-1730 against the check variety (137.09 t ha-1). Similarly, the maximum CCS of 12.08% was displayed by YtTh-1705, followed by check variety Thatta-10 with CCS of 11.73%. Whereas, the CCS% in other sugarcane genotypes was low as compared to check variety. Among the inspected sugarcane genotypes YtTh-1705 was found promising due to highly improved performance for quantitative and qualitative parameters. Therefore, can be included in the gene pool for further varietal development studies.

28-05-2022, 2021
Current study was conducted at Sugarcane Research Institute, Faisalabad during 2019-20. Preliminary Yield Trials is an important stage of varietal development program comprising on 4 th year of study. Current study was conducted to evaluate the performance of twenty six clones in comparison to two check varieties deploying randomized complete block design (RCBD) using three replications. All these clones were developed from fuzz imported from Srilanka as natural conditions are not conducive for flowering and hybridization of sugarcane in country. The data was subjected to principle component analysis based on five parameter (tillers per plant, no. of canes per hectare, yield (t/ha), sugar recovery (%) and single cane weight) and analysis of variance. The characters tillers per plant, no. of canes per hectare and single cane weight had positive association with yield per hectare. These character should be focused during selection process. The data was interpreted based on 66 percent information contained in PC-2. The linkage cluster analysis placed the clones into six major groups which were genetically different. The variation in cluster can be utilized in breeding program for further improvement. Based on superior performance, nine clones were selected and promoted to next selection stage named semifinal varietal trial for further evaluation. A clone S-2016-SL-284 outclassed all the clones in term of performance of all parameters under study which will be bright future hope to be recommended a variety for commercial release in coming years. The clone was from the fuzz of local parents exchanged with Srilanka, so local germplasm should be given key importance while choosing the parents for crossing purpose in breeding program of sugarcane. Local hybridization program may serve the purpose of desired parents having suitability in adaptation in local climatic conditions.

In an experiment, 16 early maturing sugarcane clones along with 2 checks were planted in Randomized Block Design with three replications during spring season 2016-17 at Dr. RPCAU, Pusa, Bihar to study the genetic parameters for productive traits in early maturing sugarcane clones and select the superior clones. The productive traits under studied were germination percentage at 45 & 90 days after planting (DAP), number of shoots at 120 & 240 DAP (000/ha), plant height at 150 days, 240 days (cm) & 300 days(at harvest), cane diameter (cm), fibre per cent, single cane weight (kg), number of millable cane (000/ha), juice quality traits viz, brix, pol & purity per cent at 8 & 10 th months stage, respectively, CCS per cent, cane and sugar yield (tonne/ha) at harvest. Analysis of variance revealed that highly significant differences among the clones for all the productive traits under study. Maximum range was found for the trait plant height at 150 days followed by plant height at 240 days and cane yield. The phenotypic coefficient of variance was greater than genotypic coefficient of variance for all the traits. The traits namely, cane yield, sugar yield, single cane weight, number of shoots at 120 DAP, cane diameter and germination percentage at 90 DAP showed high heritability coupled with high genetic advance as per cent of mean. On the basis of per se performance of six productive traits the clones namely, CoP 15437, CoP 14436 CoP 11437, CoLk 12207 and CoP 12437 were selected as superior early maturing genotypes. All these clones can be utilized by the farmers as well as Sugar Factories to get high yield and high sugar in early phage of crushing and also its can be further utilization for sugarcane crop improvement programme.

The remaining twenty clones were rejected due to disease susceptibility, pith and poor growth characteristics.
Yield Characteristics and Stability of Sugarcane Mutant in Three-Location Trials
Universal Journal of Agricultural Research
Bululawang (BL) has been cultivated annually under the increasing environmental pressure caused by global climate change. This condition often decreases the genetic ability and yields of agricultural products. Meanwhile, point 2.4 SDGs, specifically in sugarcane, can be achieved through a breeding program to improve and increase the genetic quality of several varieties of the plant in Indonesia. Mutation breeding to produce superior species has also been carried out by the Plant Breeding Laboratory, University of Jember, and this helped to increase the national sugarcane production. Therefore, this study aims to obtain new high-yielding varieties using the BL as the parent plant. The mutation breeding was carried out using the EMS mutagen, and this led to the production of three selected genotypes, namely M1.4, M2.4, and M3.4, which were further developed and tested for multilocation. The three selected locations for this study include Sukorambi-Jember, Arjasa-Jember, and Pakem-Bondowoso Districts. Based on the LSI test, M1.4, M2.4, and M3.4 showed the highest agronomic performance and yield in all locations compared to BL. M1.4 and M3.4 were identified to have high yield stability in the multi-location trials, hence, they were recommended as new stable superior genotypes. Therefore, M3.4 was declared as a site-specific adaptive species, which can be planted in the Arjasa and Sukorambi areas, based on the stability tests of Finlay and Wikinson, Eberhart, Russell, and AMMI.
Strategy for developing sugarcane cultivars: selecting for both broad & specific adaptations
Philippine Journal of …, 2003
New statistical tools like AMMI provide quantitative understanding of the differences in plant adaptation associated with the differences in performance and, in particular, the genotype-environment interaction (GxE). AMMI presents an analysis of the GxE that extends the classical additive main effect model for genotype and environments (ie, ANOVA) by including multiplicative terms for interactions (ie, principal component analysis). A study was conducted in four major sugarcane-growing areas in Luzon and Visayas, namely Tarlac, Tarlac; Balayan, Batangas; La Carlota, Negros Occidental; and Victorias, Negros Occidental. Twelve sugarcane varieties were evaluated using morpho-physiological parameters during the entire growth period of the plants, namely Phil56-226, vmc90-239, Phil84-77,
