“…Many studies show that the service life, pesticide and fertilizer usage, stress resistance, and yield stability of semiwild races are better than those of annual species in the ratoon cultivation of cotton ( Figure 3 ), and the annual species could be ratoon cultivated for ~3 years (Evenson, 1970 ; Plucknett et al, 1970 ; Chen et al, 2010a , b ; Zhang et al, 2020a , b ). It is worth noting that ratoon cultivation of hybrids between upland cotton and sea island cotton has been performed, which was helpful for fixing the interspecific heterosis of cotton (Komala et al, 2018a , b , c ). The benefits of ratoon cultivation of perennial cotton mainly come from three features: (1) the perennial root system, which can save costs for seed and tillage, shorten the vegetative growth period, and provide monetization from an earlier harvest; (2) the low pruned stem, which can reduce plant height and increase the number of fruiting branches; and (3) infinite inflorescences, which can extend the flowering period and increase boll number and yield ( Table 2 ).…”

Cotton production is challenged by high costs with multiple management and material inputs including seed, pesticide, and fertilizer application. The production costs can be decreased and profits can be increased by developing efficient crop management strategies, including perennial cotton ratoon cultivation. This review focuses on the role of ratoon cultivation in cotton productivity and breeding. In areas that are frost-free throughout the year, when the soil temperature is suitable for cotton growth in spring, the buds of survived plants begin to sprout, and so their flowering and fruiting periods are approximately 4–6 weeks earlier than those of sown cotton. Due to the absence of frost damage, the ratoon cotton continues to grow, and the renewed plants can offer a higher yield than cotton sown in the following season. Moreover, ratoon cultivation from the last crop without sowing can help conserve seeds, reduce labor inputs, and reduce soil and water loss. In this review, the preservation of perennial cotton germplasm resources, the classification and genome assignment of perennial species in the cotton gene pools, and effective strategies for the collection, preservation, identification, and utilization of perennial cotton germplasms are discussed. Ratoon cultivation is the main driver of cotton production and breeding, especially to maintain male sterility for the utilization and fixation of heterosis. Ratoon cultivation of cotton is worth adopting because it has succeeded in Brazil, China, and India. Therefore, taking advantages of the warm environment to exploit the indeterminant growth habit of perennial cotton for breeding would be an efficiency-increasing, cost-saving, and eco-friendly approach in frost-free regions. In the future, more attention should be given to ratooning perennial cotton for breeding male-sterile lines.

“…Compared with seed-sown cotton, ratooned annual cotton has four major advantages in terms of perennially producing hybrid cotton seeds: (1) preservation of the original root system, which reduces the time needed for root morphogenesis so that the weak seedling stage can be avoided (Chamy, 1979) and the growth duration becomes shortened (Chamy, 1979;Komala et al, 2019), allowing earlier vegetative growth of ratoon cotton when the temperature is suitable and resulting in fewer weeds because of earlier canopy closure (Plucknett et al, 1970;Fontes et al, 2006) and in lower costs associated with cultivation (Komala et al, 2018a); (2) indeterminate flowering habit, which is advantageous by extending the pollination time (Macharia, 2013;Muhammad et al, 2015) and thus results in increased seed yields (Zhang et al, 2015a;Komala et al, 2018b); (3) RA, which offers opportunities for observing annual plant performance (Kumar et al, 2011;Komala et al, 2018c), testing the effects of field chilling on mature plants (Sachs and Zilkah, 1985;Zhang et al, 2008), preserving pathogens over the long term (Mihail et al, 1987;Seo et al, 2006), and assessing combining ability and heterosis (Thomson and Luckett, 1988a,b;Komala et al, 2018bKomala et al, , 2019; and (4) the perennial maintenance of male sterility in the absence of a matched maintainer (Zhang et al, 2013;Zhou, 2016), which reduces the cost of F 1 seeds (Zhang et al, 2015a,b). Therefore, the use of ratooned male-sterile lines to produce low-cost hybrid cotton seeds has good application prospects.…”

This paper reviews an important topic within the broader framework of the use of ratoon cotton for the development of a cost-saving and efficient method for the perennial production of hybrid cotton seeds. Cotton has a botanically indeterminate perennial growth habit and originated in the tropics. However, cotton has been domesticated as an annual crop in temperate areas worldwide. Ratoon cultivation has an important application value and is important for cotton production, breeding, and basic research. In particular, ratooned male-sterile lines have four advantages: an established root system, an indeterminate flowering habit, ratooning ability, and perennial maintenance of sterility in the absence of a matched maintainer. These advantages can help reduce the costs of producing F1 hybrid cotton seeds and can help breed high-yielding hybrid combinations because ratooning is a type of asexual reproduction that allows genotypes to remain unchanged. However, ratooning of cotton is highly complex and leads to problems, such as the accumulation of pests and diseases, decreased boll size, stand loss during severe winters, and harmful regrowth during mild winters, which need to be resolved. In summary, ratoon cotton has advantages and disadvantages for the production of hybrid cotton seeds, and future prospects of ratooning annual cotton for the perennial utilization of heterosis are promising if the mechanization of seed production can be widely applied in practice.
