2 ANNUAL REPORT [CROP IMPROVEMENT] All the 8 research trials programmed for the year conveyed by the Project Coordinator, AICRP(S), Lucknow were laid down as per the technical programme and monitored by the team constituted by the Project Coordinator during Sept, The results of various trials received under crop improvement are detailed below: 1. Initial Varietal Trial Early (IVT-E) Nine test clones and two standards were evaluated in this trial for different cane yield and quality traits and data generated is appended in Table 1. The top three clones for cane yield in this trial were CoPb 13181(90.99 ), CoH (89.01 ) and CoPant (88.64 ) that were comparable to high scoring standards Co 0238 (89.65 ). The promising clones for stalk length were CoPant 13121, CoLk 13202, CoPant and Co while for stalk diameter and single cane weight were CoLk 13202, Co 13033, CoPant The standard Co 0238 was superior for these traits in comparison to test clones. For CCS (), three clones CoS 13231, CoPb and Co recorded higher values for this trait and are in comparison with both the standards. Sucrose (%) among test entries ranged from Two clones Cos (18.63%) and Co (17.63%) were better than CoJ 64 (17.22 %). Both these clones exhibited higher CCS % ( months) than the best standard CoJ Advance Varietal Trial Early I Plant (AVT-E I Plant) In this trial, four test clones along with two standards were evaluated at for cane yield and quality traits (Table 2). None of the clone surpassed the best standard CO 0238 (91.19 ) for cane yield. However, two clones namely Co (90.24 ) and CoPant 12221(87.79 ) were at par with Co 0238 for this trait. For quality traits viz: CCS % ( months ) and Sucrose % ( months), and Pol % cane, two clones Co (17.46,11.68,12.85) and Co 12027(18.15, ) respectively reflected better/ comparable performance with both the standards. 3. Advance Varietal Trial Early II Plant (AVT-E II Plant) Among four test clones and two standards evaluated for cane yield and component traits in this trial, clone CoLk (88.92 ) performed slightly better than Co 0238 (

3 ) and clone CoLk 11202(87.33 ) was at par with this standard for cane yield. Both these clones showed desirable traits like stalk length and stalk diameter (Table 3). Clone CoLk ranked first for quality traits Sucrose at month (18.0%), CCS% at months (12.69), Pol % cane, month (14.28) and Fibre % month (13.31) closely followed by CoLk for these traits, that is comparable to both the standards. 4. Advance Varietal Trial Early Ratoon In advance varietal trial early ratoon, none of the test clones surpassed the best standard CO 0238 (83.24 ) for cane yield. However clone CoLk (79.17 ), was found at par closely followed by CoLk (75.35 ).The cane characteristics like NMC, stalk length (m), stalk diameter (cm) of clone CoLk were comparable with high yielding standard Co 0238 (Table 4). For quality traits, CoLk recorded the highest CCS () (.01) followed by CoLk (9.65) and CoLk (9.63) which is comparable to both the standards. The clone CoLk was found promising for sucrose per cent (19.37 %), Pol % cane (14.08 %) and CoH fo CCs % at harvest. (13.87 %). MID LATE TRIALS 5. Initial Varietal Trial Mid-Late (IVT-M/L) Thirteen test clones along with three standards were evaluated for cane yield and component traits in this trial. Among the test clones, the top four promising clones for cane yield were CoH (97.22 ), CoLk (93.02 ), CoPant (91.26 ) and CoPb (91.78.) that were superior to all the standards. Two clones Co (2.83 cm) and Co (2.68 cm) for stalk diameter and seven clones were superior for single cane weight than high scoring standards (Table 5).Six clones exhibited higher CCS () than best standard CoPant (9. ) and among the top three clones for CCS (), CoPb (.57) ranked first followed by CoH (.45) and Co (.12).For sucrose and CCS %, clones CoH (19.31,13.58), Co (18.70, 13.13), Co (18.66, 13.) and CoH (18.59,13.01) were top performers. 3

4 6. Advance Varietal Trial Mid-Late I Plant (AVT-M/L I Plant) This trial consisted of six test clones and three standards which were evaluated for cane yield and quality attributes. The data appended in table 6 showed that all test clones were superior to high yielding standards CoS 8436 (72.56) for this trait, however top three clones for cane yield were Co (86.40 ), CoLk (84.28 ) and CoPant (83.02 ). High stalk length, stalk diameter and single cane weight were recorded for clone CoH (2.95 m,2.67 cm and 1.66 kg respectively). Top three significantly superior clones for CCS% and sucrose per cent were CoPant (12.87, 18.52), CoLk (12.71, 18.25) and CoS (12.38,17.94). Similar trends were observed for CCS () for these clones.among test clones, Pol % cane and Fibre % was highest for clone CoLk which is comparable with standards CoS 8436 having Pol % cane (14.40) and Fibre % (14.46). 7. Advance Varietal Trial Mid-Late II Plant (AVT-M/L II Plant) In advance varietal trial mid-late II Plant, nine clones including six test and three standards were assessed for cane yield and quality parameters during The most promising clones for cane yield were CoS (89.45 ) followed by CoLk (83.18 ) and CoPb 11214(82.23 ) and all these clones were significantly superior to the standards for cane yield.. The top three clones for single cane weight were Co 127 (1.34 kg), CoH (1.23 kg) and CoLk (1. kg) (Table 7). For CCS () clone CoLk ranked first (9.60) followed by CoS and CoPb All are comparable with Standard CoS 767 (8.40). All the test clones were comparable with standards for stalk diameter. The highest CCS % were recorded for CoPb (12.59) and clone CoH (12.29). CoH (17.90 %) recorded highest sucrose % among the test clones followed by CoPb (17.78) and CoLk (17.57).while standard CoPant recorded the highest Sucrose % at 12 months in this trial. 8. Advance Varietal Trial Mid-Late Ratoon (AVT-M/L Ratoon) Advance varietal trial mid-late ratoon conducted with six test clones along with three standards showed that cane yield among clones ranged from to The promising clones for cane yield were CoPb (76.47 ) followed by CoS (74.31 ) and CoLk (70.46 ) and were comparable with standards. 4

5 Two clones viz: Co 127 (2.62, 1.27) and CoH 11263(2.90, 1.) were found promising for cane diameter and single cane weight, while Co 127 and CoS were superior for stalk length among the test clones.. Clones CoPb, (9.38), CoS (9.04) and CoLk (8.46) were found superior to CoS 767 (8.17) for CCs (). Clone CoLk excelled for CCS % (12.52 %) and other three clones CoPb 11214, CoS and CoLk were comparable with all the standards (Table 8). None of the test clones surpassed the high scoring standards CoS 8436 and CoPant for Sucrose % at harvest. (Table 8). CCS % of the clone CoLk (12.52) was found to be comparable with the standards. 9. Fluff supply programme 9.1 Sowing of Fluff From 2016 crossing programme, fluff of 62 cross combinations (Bips. PCs, GCs amd Selfs) was received from SBI, Coimbatore in March and was sown in April, Thirty seven cross combinations exhibited good germination while 14 crosses did not germinated. Remaining eleven crosses showed 4-5% germination. Final count of seedlings (Table 9) and their survival in the field after transplanting will be communicated in due course of time. 9.2 Ratooning of seedling From fluff of 2015 hybridization programme, 8530 seedlings were transplanted in field during July, 2016 and were ratooned in December, These seedlings are showing good sprouting and shoot formation. Their cane characteristics and Brix data will be recorded in October-November, 2017 and selection will be made for their advancement to clonal stage I. 9.3 Clonal Stage 1 During 2016, 433 clones selected from (C0) seedlings of different cross combinations were scored for different cane traits and brix using hand refractometer. The range of data recorded is appended in Table. Based on brix and cane traits 119 clones were selected and advanced to clonal stage I for further evaluation in crop season. 9.4 Clonal Stage II One hundred seventy two clones (172) advanced from Clonal stage I were evaluated in Clonal stage II for cane traits and brix during crop season Data revealed sufficient variability among and within cross combinations for these traits (Table 11). Seventeen clones 5

6 (17) were selected for earliness and thirty (30) for midlate maturity groups and put in preliminary yield trial (PYT) for their evaluation to cane yield, its components, quality traits and disease resistance in station trials.. Technical programme During , eight (8) research trials programmed for the year conveyed by the Project Coordinator, AICRP(S), Lucknow were laid down as per the technical programme in the month of Feb-March, All trials are in progress and data on germination, tiller count has been recorded.
