“…These characters show additive gene action and improvement through direct selection could be possible for these characters. These results are in accordance with the earlier findings of Pandey et al, (2018), Negi et al, (2017b) Bora et al, (2014) and Chaudhary (2001.…”

“…The significant differences among entries for all the traits studied implies the presence of substantial variation which provides ample scope for the selection of superior and desirable clone and gives an opportunity to a plant breeder for improvement of these traits through breeding. Earlier workers Pandey et al, 2018 andBairwa et al, 2017 reported high variability for these traits in sugarcane. The genetic variability parameters studied in C2 clonal population are presented in Table 2.…”

“…Heritability denotes the proportion of phenotypic variance that is due to genotype, i.e., heritable and is act as a tool to predict the gain from selection in a population i.e., genetic advance. Genetic advance is also important as it indicates the magnitude of the expected genetic gain from one cycle of selection (Pandey et al, 2018). Knowledge about all these selection parameters plays a crucial role to improve any trait of sugarcane.…”

“…Plant height is often highly heritable and controlled by a few genes with large effects [72]. In contrast, sugarcane height, which is highly influenced by the environment, has low heritability and few genetic determinants [73,74]. The number of tillers and millable canes have moderate heritability and modest genetic effect and are instead influenced by the environment [74].…”

The high stalk weight sugarcane cultivar has a special mechanism to obtain greater growth, which was inherited from its parents. Thus far, comparisons of the high stalk weight sugarcane cultivar growth with its parents and cultivars with a low stalk weight have never been reported. The purpose of this research was to reveal the growth mechanism of the high stalk dry weight cultivar KK3 by comparing its physiological, anatomical, and morphological traits to those of a low stalk dry weight cultivar (UT12) and their four parental cultivars under hydroponic conditions. Their growth characteristics were evaluated at 15-day intervals from 30 to 90 days after planting. The root traits were measured at 2 months after planting (MAP), whereas the anatomical and physiological parameters were collected at 3 MAP. Biomass was recorded at 1, 2, and 3 MAP. KK3 had similar anatomical root traits to its female parent, whereas it had similar aboveground morphological traits to its male parent. The comparison between UT12 and its parents revealed that almost all its root anatomical traits were similar to the female parent, but it did not differ in leaf anatomy and root system size. Some physiological traits of KK3 were not different from those of its parents. In contrast, the net photosynthesis rate (PN), height, tiller number, stem dry weight, and stomatal density of UT12 were lower than those of its parent. For KK3, its small root stele and vessel size and high root length, surface area, and volume supported water uptake. The increase in stomatal density and decreased stomatal pore length may be appropriate characteristics for reducing water loss in this drought-resistant cultivar. Furthermore, KK3 exhibited a high water use efficiency (WUE) to promote biomass accumulation and growth despite its low transpiration and photosynthesis rates. This basic knowledge will be useful for selecting the parents based on their characteristics to create new sugarcane cultivars with a high stalk dry weight for drought stress during the early-growth-stage breeding programs and predicting their performance.
