“…In the present study, cane yield (CY) and sucrose content (ERS) which both determine sucrose yield per unit area showed very frequently non-significant genetic correlations which were almost null in the three programmes (LM, SB and ES) and occasionally slightly negative in one programme only (VB). Such non-significant correlations between CY and ERS have also been observed by other authors (Milligan et al 1990(Milligan et al , 1996Sandhu and Saini 1997;Baffa et al 2014;Liu et al 2016). Therefore, selection pressure exerted on one trait does not affect the other one.…”

Sugarcane variety development programmes are costly and lengthy. It appears important to periodically assess their ability to select competitive genotypes for yield components and provide genetic gains. This article reports a 10-year retrospective analysis of successive variety trials conducted in four regional breeding programmes on Réunion Island in the most advanced regional selection stage. The four variety programmes were dedicated to the humid coastal zone (LM), the per-humid coastal zone (SB), the irrigated dry coastal zone (ES) and the dry high lands (VB) of the local industry. Using mixed linear models, the objective of the study was to (1) assess genetic variabilities available for yield components in this advanced selection stage; and (2) estimate trends of genetic gains achieved over the last decade across the four programmes. Yield components were: cane yield (CY), estimable recoverable sugar (ERS), fibre content (FIB) and economic index (EI). Broad-sense heritabilities were high (0.70-0.91) for all traits in each programme. Mean genetic coefficients of variation were about twice as high for CY (14.1%) and EI (15.5%) compared to ERS (5.7%) and FIB (6.6%). A higher probability of identifying superior varieties was found for CY and EI in two of the four programmes characterized either by thermal and hydric stresses (VB) or by an edaphic stress (SB). Simple linear regression of variety performances versus years of selection revealed trends in genetic gains for EI ranging between 0.53 and 1.81% increase per year that were highly significant (P \ 0.001) in the two programmes (LM and VB).

“…The evaluated genetic parameters and components were similarly expressed, regardless of the water regime, for all analyzed traits. Similar responses between well-irrigated and water-stress conditions have been reported, where the reduction due to water stress is up to 50% for cereals [1,28,29] and grasses [30,31].…”

To define breeding strategies, the understanding of trait inheritance is critical. The objective of this study was to determine the inheritance of popcorn under different water regimes. To this end, Hayman’s diallel methodology was used, with 8 parents and 28 hybrids. The experiment was carried out under well-watered conditions (WW) and water stress (WS). For popping expansion (PE) under both water regimes, the effects of complete dominance and greater importance of the components associated with the dominance effects were observed. In contrast, the number of dominant genes was zero and the determination coefficient in the narrow sense was >50%; additive effects were also present. For the number of grains per row (GR), ear length (EL), and grain yield (GY) under WS and WW conditions, the dominance effects were the most relevant, and the mean degree of dominance with overdominance effects and greatest relevance of the components associated with this effect were also observed. The same breeding methods can be applied under the studied WS and WW conditions. Exploiting heterosis for GY and related components is a promising way to adapt popcorn to WS. To be able to capitalize on additive and dominance effects, a reciprocal recurrent selection is recommended.

“…Dari beberapa faktor yang mempengaruhi produksi gula yang dihasilkan tanaman tebu, kondisi iklim pada lahan pertanaman tebu menjadi faktor kuat yang mempengaruhi produksi gula (Toharisman dan Triantarti, 2016;Zhao dan Li, 2015), termasuk kondisi iklim. Perubahan iklim berpengaruh pada panjang periode kering dan periode basah (Loo et al, 2015), yang berpengaruh pada laju pertumbuhan tanaman tebu (Jaiphong et al, 2016;Khonghintaisong et al, 2018;Liu et al, 2016). Beberapa usaha untuk meningkatkan produksi gula adalah perluasan area tanam tebu (Muhaimin dan Sari, 2017;Sari et al, 2015;Suryani et al, 2018), dan penerapan teknik budidaya tebu yang efektif-efisien meliputi pengaturan irigasi (Olivier dan Singels, 2015), dan waktu tanam yang tepat (Ramos et al, 2016;Sari dan Wegener, 2015).…”

Sugarcane productivity is naturally affected by climate variables and limited by the water availability. This study simulated a water balance model to estimate sugarcane water requirement and to estimate the best planting time as well based on its optimum productivity in Kediri Regency. Water requirement was estimated by water loss of evapotranspiration following FAO No. 24, while the productivity was based on mid-maturing sugarcane growth and development. Sugarcane rainfed area in Kediri Regency needs approximately 26-128 mm water per month based on its loss by evapotranspiration. The value varied due to the growth phase. More than 60% water was used in vegetative phase for developing buds and stem elongation of about 3-9 months after planting. The highest sugarcane productivity was obtained in July-September as the best planting time shown by simulation. Moreover, water deficiency during mid-season of sugarcane growth could decrease productivity by a significant amount. The work presented here could be used as a tool to help decision makers for irrigation management and select the best planting date.
