Stability analysis and performance of promising sugarcane varieties for yield and quality traits

Abstract

Four promising varieties of sugarcane, along with the commercial variety, GT54/9 were evaluated for yield, yield components, and quality traits. The environments were different ages of harvest time (11, 12, and 13 months old) of two plant cane crops (2-years) at El-Mattana Agriculture Research Station farm during (2018-2019 and 2019-2020 seasons). The stability analysis of studied traits was performed. The results indicated that the promising varieties, environments, and their interaction had a highly significant effect on all studied traits in both the seasons except the age at the harvest time on purity in both seasons, the effect of the interaction on sucrose as well as a pol in second season only and on fiber in the first season only. It is obvious from the results that none of the tested varieties was superior to GT 54/9 for cane and sugar yield and stable implying the necessity of widening the genetic base to produce improved promising varieties. The stability analysis showed that GT 54/9 variety was stable for stalk height, stalk diameter, brix, reducing sugar, and fiber and recorded the highest cane yield and sugar yield. G2003/49 was stable for cane yield, sugar yield, brix, pol, and fiber. It ranked third in cane yield and the second sugar yield. The variety G2003/47 was stable for stalk diameter, sucrose, sugar recovery, and fiber and ranked fourth for cane yield and the third rank for sugar yield. G2004/26 was stable for stalk diameter, cane yield, reducing sugar, and fiber. It occupied the second and third ranks for cane yield and sugar yield respectively. G84/47 variety was stable for cane yield, sugar yield, brix, sucrose and fiber and ranked last for cane and sugar yield.

CoPb 14185: A midlate sugarcane variety for North West Zone of India

“…IVT was conducted during 2017-18 in NWZ at nine locations over five states (details given in the materials and methods section). Based on the ongoing research on sugarcane, a wide range for CCS (t/ha), cane yield, CCS %, sucrose % and other contributing traits have been well documented (Anonymous, 2018;2020;Singh et al, 2021) that cane yield contribution is more than sucrose content in the improvement of CCS t/ha (commercial cane sugar) (Gonzales and Galvez, 1998;Jackson, 2005;Abuellail et al, 2021;Saravanan et al, 2021). Clone CoPb 14185 exhibited higher per se performances for cane yield as well as sucrose %, both, when compared with standards (Table 1 and 2 All the 13 test clones along with standards were screened (Ali et al, 2007;Kaur et al, 2016).…”

“…During the 2018-19 crushing season, sugar recovery of India was reported to be improved with 11.01 % (Sugar statistics, 2021); because of the changes in varietal scenarios and post-harvest management practices especially in Uttar Pradesh of subtropical India. These differences in state wise cane production, productivity and sugar recovery reveal the possibility of huge potential gain for increasing cane & sugar productivity through improved cultivar (Abuellail et al, 2021;Saravanan et al, 2021). Henceforth, it is a need to develop high yielding cultivars which could boost provincial as well as national cane sugar yields.…”

Biplot analysis of non parametric measures of stability for long term evaluation of fababean genotypes

“…Faba bean (Vicia faba L.) is cultivated in almost seventy countries for its beneficial nutritious properties for human food and feed worldwide (Sarah et al, 2009;Khazaei et al, 2021;Sharan et al, 2021). Development of high yield and stable genotypes by breeders for large scale cultivation across the diverse environmental conditions for their adoption by farmers needs not to be elaborated (Tekalign et al, 2019;Papastylianou et al, 2021;Abuellail et al, 2021). Long term evaluation trials are to be conducted before the release of genotypes for specific and general adaptations of the promising genotypes as climate change sets new challenges to major crop species especially to faba bean for their successful adaptation to stressful environments (Tadele et al, 2017;Raiger et al, 2021).…”
